Ubuntu :: Read Host CPU Temp From Guest OS?
May 16, 2010
Is it possible to read the host cpu's temperature from a virtual guest?
(1) Where host = ubuntu desktop and guest = ubuntu server, and
(2) Where host = windows xp and guest = ubuntu server?
Typically I would read the contents of /proc/acpi/thermal_zone/THRM/temperature on host ubuntu desktop. I guess its more tricky when running ubuntu on windows host. What I am trying to do is shutdown guest if host cpu temperature is greater than certain value.

I have a web server whos DocumentRoot is:/tmp/wwwNow, /temp/www/fake/ is a directory that contains a series of other files/folders.What I want to do is access the files in /temp/www/fake as if they were in the root directory (/temp/www/)For example:
could either be located in "/temp/www/test.php"
-or-
located in "/temp/www/fake/test.php"
so "http://127.0.0.1/test.php" would essentially call both directories. Is this possible? Whould I do this through apache or through the actual file system somehow? (Like some sort of symbolic link?) I would love to hear your input.

I'm running Ubuntu 10.10 desktop in a VirtualBox VM on a Windows 2008 host machine. The end goal is join the the Ubuntu VM to a Windows 2008 domain. I've downloaded likewilikewise-open_5.4.0.42111-2ubuntu1.2_i386.deb se-open_5.4.0.42111-2ubuntu1.2_i386.deb to get the joining of the VM to the domain. But from this point forward, I'm completely lost.
1) How do I implement this likewise package?
2) How do I get files from my Windows 2008 host to the Ubuntu guest VM?
The likewise file is burned to a DVD. When I try to read the DVD, I get the "My Disk" icon but only one file gets displayed. In other words, the DVD the likewise file is burned to has a ton of files. Ubuntu doesn't see any of them expect one .exe file. The /etc/fstab had no entry for cdrom, so I put a line in that says
/dev/hdc /media/cdrom0 udf,iso9660 user,noauto 0 0 rebooted and that didn't do squat. There is no entry /etc/cdrom but there is directory /etc/My Disc. And I suppose that's what gets mounted because I can see one file on that disc. So then I thought, to hell with the DVD drive and I'll just get the Linux guest to see a "shared drive" on the host. I shared out a folder on the host via the Virtualbox "shared folders". But how I get the Ubuntu guest to see this shared folder is as big a mystery to me as is the creation of life.

I have a host with 4 VMs on it. How do I move them to another host? The first host is dying and I want to move the VMs to another host. I tried to copy the files under /vms from one host to another and then copy the files under /etc/libvirt/qemu to the other host. I then ran "virsh" and it does not see them.

My Windows guests see my VMware Host Only folders as \.hostShared Folders. But when I try to see them from a Linux guest, all I get is frustrated. No permutation of that seems to work. Because the Windows guests see the shared folders I know the host is doing its part in providing them. After two days of not finding an answer on the VMware Workstation forum I finally figured out that the problem really is how to look for them with Linux. With Linux I can turn off all NICs accept the Host Only NIC, put smb://172.16.138.1 into the address bar and see all the shares on the host, but not the folder designated as the host only folder. How to look for the shares with Linux?

I have installed Red Hat Eterprise Linux as a Guest OS using VirtualBox on the Host OS Windows XP SP 2 on my PC. I want to access my local / intranet web site from this Guest OS which is running on the top of on Windows XP, the Host OS. I am not sure as to what IP Settings I need to do. Though I am able to access Internet from both the OSes. The IP of this Guest OS is:
Code:
[root@localhost ~]# ifconfig eth0
eth0

I have installed Microsoft Self Loop Adapter (Autoconfiguration IP Address: 169.254.25.129) on the Host OS Windows XP. There is another adapter: VirtualBox Host-Only Network whose IP Address is: 192.168.56.1. So, how can we access intranet web site from the Host OS to Guest OS and vice versa. I also want to access this virtual Red Hat machine /console from within windows XP using PUTTY application. From Windows XP the Red Hat machine is pinging. But when I use the IP to access the machine through PUTTY it doesn't work.

Migrating Virtual Guest to Native Host
I have been using ubuntu server and desktop on virtual box for a while now. I have come to enjoy it more than being in Windows. I would like to install it natively. I am wondering. is there any way I can take my virtual machine and apply what I have done there to a new ubuntu install?
I have a ntfs hard disk, will ubuntu resize that for me at install?
Any good apps for backing up all my my firefox data and then applying that to my firefox in ubuntu?
I need to keep windows for some stuff for work, and for some games I like.

I just upgraded to the newest VirtualBox, version3.2.4.r62467 and installed Ubuntu 10.4/64 guest on an Ubuntu 9.10/64 host. I installed the guest additions and set 3 shared drives. I can see them in the "machine folders" names, paths and access modes in the "shared folders" dialog. But, when I try to write to them, I always get Permission Denied!
I mounted it as root:
mount -t vboxsf tera /vb/tera
It shows up in mtab:
root@ubu-10:/vb# grep tera /etc/mtab
tera /vb/tera vboxsf rw 0
I can see the listing:
root@ubu-10:/vb# ls /vb/tera
bak Recycled <snip>
But, the permissions are wrong and can not be corrected. Chmod and chown are ignored?!
root@ubu-10:/vb# ll /vb | grep tera
drwxr-xr-x 1 root root 12288 2010-05-04 09:42 tera/
root@ubu-10:/vb# chown brianp /vb/tera
root@ubu-10:/vb# chmod 775 /vb/tera
root@ubu-10:/vb# ll /vb | grep tera
drwxr-xr-x 1 root root 12288 2010-05-04 09:42 tera/
I am running as root:
root@ubu-10:/vb# whoami
root
The VB shared folders dialog, machine folders shows /tera with access Full. /etc/mtab confirms that it is rw
I own it on the host:
brianp@trex:~$ ll / | grep tera
drwxr-xr-x. 16 brianp root 12K 2010-05-04 09:42 tera
Why can't I write to it?

I have VirtualBox v3.1.0 r55467 running on f12 2.6.31.6-162.fc12.i686. The guest is Windows XP SP3. I need to enable bridged mode for the virtual network interface on the guest. Everytime I enable bridge mode the following error occurs.
Quote:
Failed to start the virtual machine Windows XP. Failed to open/create the internal network 'HostInterfaceNetworking-wlan0' (VERR_SUPDRV_COMPONENT_NOT_FOUND). One of the kernel modules was not successfully loaded. Make sure that no kernel modules from an older version of VirtualBox exist. Then try to recompile and reload the kernel modules by executing '/etc/init.d/vboxdrv setup' as root (VERR_SUPDRV_COMPONENT_NOT_FOUND). When I run '/etc/init.d/vboxdrv setup' i get the following compilation error:

I have tried a few times already the following procedures: start a new installation (each time, I create a new VBox VM) with the Fedora 12 DVD iso attached to the DVD drive of the VM. I select the default setting, like US english, US keyboard, local time (GMT +8), standard installation ... etc). The installation process had been smooth to the screen the system asking for a reboot after installing something like 1100+ packages. Then I click the reboot button offered. The VM restarted but each and every time, it came up with the following error message:
Booting from local disk...
FATAL: INT18: BOOT FAILURE
There was no other error message durint the installation process. It would be very much appreciated if some one can tell me what went wrong and how to solve it. I believe even I try again the same way, it will end up with same result. Is it a software or hardware problem? In case software problem, is it Fedora or VirtualBox?

I have Linux installed on my harddrive, sometimes I run it as the host operating system and sometimes run it as a guest in Windows using VirtualBox. It's a nice ability, I think.
I don't think it's possible with Windows though. Is it because your average distribution includes drivers for everything known to man? Are devices/drivers configured statically in Windows so when somethings changed it breaks?

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?

pretty comfortable at the command line and in kde. found 2 'supplementary kernel drivers' for virtualbox at slackbuild (thank you heinz!). followed the how-to at slackbuild and built and installed both packages, but additions weren't working. (i thought they were standalone) noticed the 'supplemental' in their description, and so installed the guest additions for linux from vbox site. additions still not working. at this point i start restarting my slackware vm, and redoing everything in various sequences. finally, additions work! but i'm not sure why! critical pieces and sequence for getting guest additions working once i have slackware installed?

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.

I run KVM on 9.10 host and guest 9.10. Both are x64. When I halt the guest os:
My host OS looses its connection with internet for 10-15 seconds and then it comes back on. Probably something goes wrong with default gateway, as it looses only external network (I still can reach it on my internal network). I've googled a lot, but cant find anything about that. I use bridged network.

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.
