Ubuntu Servers :: VMWare Guest - VFS Unable To Mount
Jul 21, 2010
I've built a customized 2.6.32 kernel over Ubuntu 10.04 server (physically) -note: it is the same version that comes with the livecd-. Then I added my stuff, cloned the disk, applied it to 3 different hardware boxes and it works perfectly. But when I put that image on a VMWare Workstation 7.1 or VirtualBox machine it doesn't load... I get a "kernel panic: not syncing vfs unable to mount root fs on unknown-block 0,0". So, I've created a new vm, I've installed ubuntu and it booted without a problem.
I ran my kernel patching as I did on the physical machine, but when I rebooted with the new kernel, I got the same error. So, the problem seems to be something in the customized kernel, but specifically going over virualized copies. By the way - In a previous version, specifically Debian 5 with kernel 2.6.18, I did the same stuff about a year ago and the machine loads perfectly in any virtualized environment. Then, the only thing left to think about my problem is that some grub parameter or kernel driver or something is messing up with booting. The customization of the kernel is only the patching for IMQ stuff.

I'm running VMWare Server 2.0 on WindowsXP as host.I have guest O/S Linux Fedora 8. i cannot access USB drives on my VM. USB drive shows up on the VMware console window as part of my devices, like CD/RW drive, etc. But for the usb drive, it is GREYED OUT./proc/partitions never shows a USB device upon connection of the drive. I have tried googling this to death and found no solution that works.

I'm a NOOB to CentOS and Linux in general. I've been trying to find a way to mount my USB flash drive (FAT32) so I can see my files. I've been told that I need to add a USB controller. My CentOS is running as a VMWARE guest in WS7 loaded on a Vista host. My physical hardware is a Toshiba Satellite notebook. I've been told I have to add a USB controller before I can mount. Can anybody give me some direction with this?

When I run as a VMWare Player guest (Win7 host), I sometimes lose keystrokes (several times a minute) or have repeat keys like thissssssssssssssssss (not as often).This doesn't happen with WinXP guest on the same VMWare installation, or Suse running outside VMWare on the sam hardware, so I suspect the combination of Suse guest + VMWare Win7 host.

I can no longer drag files from my ubuntu host into my XP guest. I have vmware tools installed in XP and up until recently I could simply drag whatever I wanted back and forth between the systems. When I try to drag a file across into XP the cursor has the plus sign like it would normally to drop a file in, but now it also makes a selection box on the XP desktop. Same problem in Workstation and Player. I haven't posted on the vmware forums yet, I figured someone here probably has had the same problem. I don't think it was a kernel update. I restarted ubuntu with 2.6.31.18 which was fully functional before, still with the same problem.

Not sure if this post belongs here, but here it is.
Host: Win server 2003
Guest: Ubuntu server
Host: IS able to ping guest. Firewall is OFF. NOT able to access guest (which is a web-server) at browser.
Guest: NOT able to ping host. Running a web server, you can check the website: (pegajosa.com) is running under that virtual Linux server.
Problem: guest needs to access host's sql database and/or any resources.
Network: is bridged.
At the Linux box ifconfig -a code...

I have annoying problem. My setup is the following: debian Linux, 64 bits, VMWare workstation 7 host, with Windows XP running as guest. From Firefox, or Internet Explorer, I am unable to access few sites, for example nvidia.com, osdir. Basically get connection timed out, on the other hand ping works to those sites. Moreover, Slashdot loads very very slow and sometimes gets horrible text-only version.
everything works fine on Linux host
I suspect it has something to do with routing on Linux, I recall having similar problem long time ago, which was fixed by setting something in /proc.
I tried setting MTU and TCP window size on Windows lower, but did not help

I have been using VMware Player for some time to host Fedora VMware images on Windows XP. I have been using Fedora 11 and 12 (both 32 and 64 bit) and recently started to use Fedora 13.
I use as a base the images provided by thoughtpolice. http://www.thoughtpolice.co.uk/
I usually install VMware tools and also keep the images updated (yum update) which sometimes changes the kernel.
I have recently had problems with the snapshots not having a network when I restore them. So far I don't have the problem with Fedora 11 and do have it with Fedora 12 (but used not to). I do have it with Fedora 13.
In each case the problem goes away when I uninstall the VMware tools and comes back when I install them again.
One of the symptoms is that SElinux complains about not being able to do something with /var/run/vmware-active-nics.
It looks to me that something is incorrect in the actions being taken when the snapshot is being restored. It does not happen every time and sometimes the network restores itself.
The network can be restored by rebooting the image.

shall explain my problem step by step! so that you all can understand!
1. Out of 120gb hardisk, i created an 100mb in the first cylinder of the harddisk and installed the "symantec boot magic" for dual boot option after switching on the system.
2. Next 70gb is for windows and installed the same.
3. Rest were for "Linux" !! In which i created on 100mb for "/boot" loader files, then one 1gb for "swap" area and the rest of the memory for "/" mounting point.
4. After all, i installed the "VMWARE" in windows, and while selecting the mount of linux, i selected the respective linux portion, and did the other settings.
5. Once done with this, i powered on the machine in vmware, but it was saying "BTMAGIC" not able to find, install again..
6. Cant we not mount the linux via "vmware" which is installed in windows, as i had used "symantec boot magic" for mounting windows/linux??

I recently started to use Ubuntu in VWware player on my windows-XP. I installed ubuntu 10.04 few days ago, It was working fine.
Yesterday, I compile a new kernel, kernel 2.6.33 in my vmware ubuntu 10.04. Everything went well till I did reboot. before reboot I use the command "update-grub" to make it compatible to the new kernel. BUT... after rebooting, I have a problem in loading a grub correctly. it gives me following message " [2.149136 ]kernel panic - not syncing: VFS: unable to mount root fs on unknown-block(0,0)" and I can not proceed further. I have my all data on it. I also tried to boot it from live CD but unfortunately, I can't mount the hard disk on it in order to get those data from my old Ubuntu set up.

Can anyone help me with how to create an init.d script that will startup a vm machine in virtualbox at boot? I found this script:[URL]..But it is for ubuntu. I am running fedora 12 x386 and using it as an Amahi server. Very cool, but it would be extra cool if I had a virtual windows machine startup when I booted up this server. Then I could just rdp into it when I needed something in windows.

I'm trying to install the Guest Additions for a VM running a guest Lucid Lynx Server. The problem I'm encountering is this: The vboxadd-install.log for vbox says it "couldn't find the sources of your current Linux kernel" and to "Specify KERN_DIR=<directory> and run Make again."

I am installing VMware-server-2.0.2-203138.i386 on FC 12
Have an error when executing vmware-config.pl initially. When I try again it has the message:-
start of messages;
The following VMware kernel modules have been found on your system that were not installed by the VMware Installer. Please remove them then run this installer again.
vmmemctl
vmci
vmxnet
vmhgfs
vmblock
I.e. - 'rm /lib/modules/2.6.31.12-174.2.3.fc12.i686/misc/<ModuleName>.{o,ko}'
Execution aborted.
End of message
I tried remove them using modprobe e.g.
modprobe -r -v vmemctl the response was "WARNING: All config files need .conf: /etc/modprobe.d/anaconda, it will be ignored in a future release."
Subsequently I tried vmware-config.pl, but have the same error.

I'm running Ubuntu 9.1 i386 in test with Vmware 2.0.2. I used Radu Cotescu's patch and instructions to get vmware installed. Everything seems to be running fine in the guest machine (CentOS 5), except I can't ssh from the Ubuntu host to the guest machine.
This guest is a clone of one that is running under on my Ubuntu 8.1 host and networking is fine there. I'm wondering if there were changes to routing or bridging in Ubuntu 9.1 to cause this. I've been digging through google for a while, but haven't seen others reporting any issues. This is definitely particular to Karmic Koala though.
The host's routing table is:
Code:
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 * 255.255.255.0 U 2 0 0 wlan0
192.168.0.0 * 255.255.255.0 U 0 0 0 vmnet3
[code]....
My routing table on the Ubuntu 8.1 host differs by the link-local line only, and the guests are exactly the same.I can ssh from the guest into the host, as 192.168.0.2 is the hosts ip on the vm network. The host should be able to ssh to the guest as it does in Ubuntu 8.1.

Red Hat Enterprise Linux 5 kernel supports four I/O schedulers:
- cfq (Completely Fair Queuing)
- deadline
- noop
- anticipatory
I read in documentation that the recommended kernel line settings for 64-bit Red Hat Enterprise Linux 5 running as a VMware guest are:
divider=10 notsc iommu=soft elevator=noop
But for single instance databases with dedicated storage the deadline scheduler is recommended. The deadline scheduler reorders I/O to optimized disk heads movement and caps maximum latency per request to prevent resource starvation for I/O intensive processes. I have an Oracle instance on RHEL5 running as a VMware(ESX) guest with dedicated storage. What scheduler is better in my case?

I have a new public mail server running under Vmware Server 2.0 installed on Windows Server 2008. I'm not satisfy about performance, virtual machine has got 3gb of ram and 2 virtual cpu. Physical machine has got one intel xeon cpu 2.4ghz quad core, 8 gb of ram and 3 hdd 500gb raid5. I already set this option: Fit all virtual machine memory into reserved host RAM. How can I increase performance? Are there any kernel build for virtual installation?

I am trying Lubuntu 10.04 as a guest in VMWare Workstation 6.5.4. My host is a Windows XP SP3 PC (soon to move to Ubuntu 10.04). The installation went fine and the vm seems to be working perfectly - all latest updates were applied and all the supplied software works.
However, the only item that is annoying is that Lubuntu always start up with 800x600 screen resolution. I can set the resolution to the one I want (1152x864) using Preference -> Monitor Setting but when I restart the vm again, Lubuntu always defaults to 800x600. BTW, my LCD monitor has a native resolution of 1920x1080 - a screen resolution of 800x600 is simply too small for my needs.
I note that there is no xorg.conf in the /etc/X11 directory and after researching the internet, I also found out that this is normal for the version of X that Lubuntu uses. I also tried out the 'xrandr' command on a console - this also works in setting the screen resolution to 1152x864 but it also is NOT persistent across restarts.how do I make the vm always start up in the resolution I want - 1152x864? I don't want to fiddle around in xorg.conf if this can be avoided.

[There are quite a few outdated guides relating to older versions of Fedora, so I figured that I'll write it up specifically for Fedora 12 to make life easier for others]
This guide is based on a fully patched Fedora 12 distribution as of Feb 5 2009.
A default install of Fedora 12 as a VMware Image (Guest) will generally fail to install VMware Tools for the following reasons (In the Fedora 12 Guest Image):
1. GCC and related packages are not installed
Make sure that 'yum list gcc*' has at least the following packages installed (these are not installed by default unless you select developer configuration).
[root@localhost ~]# yum list gcc*
Loaded plugins: presto, refresh-packagekit
Installed Packages
gcc.i686 4.4.2-20.fc12 @updates
gcc-c++.i686 4.4.2-20.fc12 @updates
2. Correct kernel-devel packages are not installed. This generally manifests itself via the following prompt:
'What is the location of the directory of C header files that match your running kernel?'
Fedora 12 installs kernel-PAE by default instead of the normal kernel rpm for the i386 distribution. Consequently, the header files required by vmware-config-tools.pl are found in 'kernel-PAE-devel' and not 'kernel-devel'.
[root@localhost ~]# yum list kernel*
Loaded plugins: presto, refresh-packagekit
Installed Packages
[code]...
The symlink /lib/modules/2.6.31.12-174.2.3.fc12.i686.PAE/source should work if the correct kernel-*-devel package is installed. vmware-config-tools.pl seems to only check this link to determine if it has found a legitimate kernel header directory.

I'm trying to install the vmware tools in Fedora 13. I've run the following commands as root:
yum install gcc -y
yum install kernel-devel -y
./vmware-install.pl
...
when it asks for the location of the directory of the C header files that match my running kernel I entered:
/usr/src/kernels/2.6.33.4-95.fc13.i686/include
but vmware-install.pl says:
The path to "/usr/src/kernels/2.6.33.4-95.fc13.i686/inc" is not valid..

I have VMWare on a notebook, guest Windows running on Linux host. The network in that virtual machine is configured as NAT. I want to share/transfer files from Linux (host) to Windows (guest). So I leave sshd always running on the notebook, I go into Windows and run an SSH/SFTP program. My Wifi router has address 192.168.1.1, my desktop has address 192.168.1.2 and my notebook has address 192.168.1.3. On the notebook, that SSH/SFTP program connects to 192.168.1.3 (i.e. the notebook itself) and everything works fine. But it's a notebook, and when I leave home with it, 192.168.1.3 is no longer accessible. How can I let the guest OS connect to the host OS when I'm away from my Wifi network?

we are running dedicated server with CentOS. We installed VMware in order to run a win2003 server. the problem is we need to access that server from outside (public).
1. the centos server has 2 NIC cards: eth0, eth1, eth2 with 2 public ips.
2. when vmware was installed we bind it to eth1.
3. we tried assigning eth1's public IP to the vmware machine and its not able to access anything outside.
4. tried to use NAT, bridged and host-only and no luck.

I have debian8.2 installed in VMware 12 with gnome desktop as guest os.
It boot into gnome successfully. But it will not boot into CLI mode and recovery mode. While boot into CLI, It is stucked in a blank screen, no cursor, after long long boot log splash in the screen.
To boot into CLI rather than gnome, I just set default.target into multi-user.target for systemd. I checked the syslog for boot into CLI, found that systemd execute getty 1~6, but it seemed to no success log and it seem to no other log for systemd. Is it failed to getty?
I check the grapyical.target and multi-user.target in systemd, find multi-user.target is the only one target required by graphical.target. Multi-user.target can be execute successfully during boot into graphical mode, while it will not be successfully execute during boot into CLI mode. That's is so unpredicted. Is there something else I missed?

I am running VMware workstation on a Linux host and WinXP guest using NAT. I have shared a folder on WinXP, and I am able to mount it on the linux host with:
mount -t smbfs -o username=Administrator,password=mypasswd //192.168.100.129/Shared /mnt/tmp
This works fine. However, I want to mount the same folder from a different linux machine (not the host).
I added port forwarding in /etc/vmware/vmnet8/nat/nat.conf:
[incomingtcp]
#445 = 192.168.100.129:445
If I run:
mount -t smbfs -o username=Administrator,password=mypasswd //external_ip_number/Shared /mnt/tmp
I am getting:
mount error 112 = Host is down
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)
It doesn't work even if I try the above command from the linux host itself. It only works if I use the internal IP number. I suspect vmware is not forwarding port 445 but I am not sure how to verify it. I am not running smbd on the linux host, in case that make any difference. I didn't think that was required because the server is really on the WinXP and the linux is just a client.
