CentOS 5 :: Timedrift In Vmware Server?
Jun 25, 2010
Be it with different options to grub.conf... different options to vmware .vmx file ...
Configuration: host box that have an Intel Quad Core CPU Q8300.
Host is CentOS 5.5 64bit, VmWare 1.0.10, guests are CentOS 5.5 32bit (and an Ipcop test box that have 2.4.x kernel)
Considering the 3 CentOS 5.5 32 bit guests (same config for grub and ntpd), I have 1 VM that usually havent' any timedrift, the remaining 2 VMs gain about 15 mins every hour (!!!). constantly, indipendently from load or Similar problem for the IpCop VM.
I need to disable ntpd daemon and put a cron job because ntpd seems not work (but manual ntpdate work, so no fw problem). Sometime is one of the VM that have no driftime problem; after some host reboot, is another. No matter how I configure it (apparently). The VM's hwclock have little or no drift, the system clock have the drift ... I can't find any logic on this ... Some months ago I use Vmware Server 2.x, but switched to 1.x for the annoyng glib problem and the not appreciated new interface. Initially no problems, next (little time before updating the host from 5.4 to 5.5), problems started ... so no apparent ralations with update from 5.4 to 5.5.

I have a few mail servers, a mail log server and a web server running on Centos 5. Now I have a task: to avoid accidental crashes on the production servers while installing updates, my boss asked me to do clones (these clones will all be VMware virtual machines) of the servers (EXCLUDING the actual e-mails and log contents) and then to run those clones on VMWare Server. This way, first I will install and test updates on the clones and - if they will be running without crashes - I will apply the updates on the real production servers themselves.
I have already installed VMWare Server 2.0 I have a few questions: How do I build the virtual machines to exclude the actual mail files and mail logs? Can I use VMware Converter for this purpose, or do I have to use another program? How do I actually do this cloning? Is there a tutorial on how to do this?

I have an i5 Thinkpad running Windows 7 64-bit. VT is enabled in the BIOS. I have installed vmware server v 2.0.2 but am unable to install Centos 5.5 x86_64 as a guest OS. The steps that I followed are as follows:1. Created a new VM, specifying RHEL 5 64-bit as the intended guest OS (per vmware documentation - Centos is not available as a selection2. Downloaded all 8 iso files for Centos v5.5 64-bit3. Modified the CD/DVD drive to 'connect at power' and use an iso with the path pointing to the x86_64 iso 1 of 8When I power up the VM, the console window displays 'ISOLINUX 3.11 2005-09-02 Copyright (C) 1994-2005 H. Peter Anvin' and nothing else. The installation splash screen never appears. As a test, I downloaded the first of 7 iso files for the 32-bit version of Centos 5.5 and pointed the CD/DVD drive to that iso. In that case, the installation starts as expected. I would really like to get the 64-bit version installed and running.

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 have a Centos 4.8 linuxbox running in VMWare ESXi 4 and the kernel is 2.6.9-89.0.11.ELsmp. Recently, this linuxbox is quite unstable, it has kernel panic once a week... But we didn't have any configuration changes on it. And I have attached the kernel panic console screen and lsmod for the server.[URL]...

I performed a system update yesterday to CentOS version 5.4. Now I cannot get vmware to start. I get the error "VMware Server is installed, but it has not been (correctly) configured for the running kernel. To (re-)configure it, invoke the following command: /usr/bin/vmware-config.pl." I tried running vmware-config but that did not resolve the issue. I saw the bug related to 2.0.x (after the update), but that does not seem to apply to 1.0.9.

I can't install centos 5 on vmware esxi 4 server.I use the netinstall cdrom and I get the splash screen with the kernel menu.After this, I can choose a language but then I get this error: "The CentOS CD was not found in any of your CDROM drives. Please insert the CentOS CD and press OK to retry."
I have tried it with the image on the datastore, a unc-path and as physical cdrom.I have tested all modes in the vmware cdrom settings (passthrogh IDE or Emulate IDE) - nothing helps.
Console 3 shows me:
loaded mptbase from /modules/modules.cgz
loaded mptscsihfrom /modules/modules.cgz[code]...........

I have installed fc12 on my core2due machine, and I have installed the vmware server on it, its rpm is installed successfully with out any error, after that a message is displayed
The installation of VMware Server 2.0.2 for Linux completed successfully. You can decide to remove this software from your system at any time by invoking the following command: "rpm -e VMware-server".
Before running VMware Server for the first time, you need to configure it for your running kernel by invoking the following command: "/usr/bin/vmware-config.pl".
I tried this command and find the this message
[Akram@localhost Downloads]$ su -c "/usr/bin/vmware-config.pl" Password: Making sure services for VMware Server are stopped.
None of the pre-built vmmon modules for VMware Server is suitable for your running kernel. Do you want this program to try to build the vmmon module for your system (you need to have a C compiler installed on your system)? [yes] yes
Using compiler "/usr/bin/gcc". Use environment variable CC to override.
Your kernel was built with "gcc" version "4.4.2", while you are trying to use "/usr/bin/gcc" version "4.4.3". This configuration is not recommended and VMware Server may crash if you'll continue. Please try to use exactly same compiler as one used for building your kernel. Do you want to go with compiler
"/usr/bin/gcc" version "4.4.3" anyway? [no] yes
What is the location of the directory of C header files that match your running kernel?[/usr/src/linux/include]
Now it asks me in last lines that "What is the location of Directory of C header files that match your running kernal?"

Sadly, I google'd the heck out of this and even the vmware community has no answers. So, I decided to turn to the experts and see if you can provide a better solution than [URL]. The system sees both CPU's and all of the cores (cat /proc/cpuinfo). I have tried with HT and without HT (I never run HT anymore; seems to hurt performance in my workloads). I've tried the recent and newest kernels for CentOS 5.4 and still have no luck. There seems to be lots of people having this issue, but no real solutions.

I'm trying to learn Linux and have created a VMWare guest operating system using CentOS 4.8. I expect the next step is to install ssh in order to transfer files to the server but as of yet I haven't figured out how to assign it a host name or how to effect a transfer.

I can install VMware Server 2.0.1 on CentOS 5.3 (32-bit and 64-bit) perfectly. However, I can't access Server's web interface by going to port 8222 on the machine's IP address. When CentOS 5.3 (32 or 64-bit) is loading, I am greeted with this message "VM communication interface socket family: vsock: no version for "VMCIDatagram_Send" found: kernel tainted." I assume this is the reason why I can't access my Server through a web browser. How do I correct this? Is there a package I need to install on CentOS prior to installation of Server 2.0.1?
It's strange, because I can install 2.0.1 on Ubuntu Server 8.10 with absolutely no problem and access its web interface. So I think this might be a CentOS-specific issue I've uncovered.

The connection to the server was reset while the page was loading. The network link was interrupted while negotiating a connection. try again.

I'm running CentOS 5.5 x64 and have just installed VMWare Server 1. I am able to create a new Virtual Machine, but when I go to power on the VM in order to install the OS (windows server 2003), either the host crashes/reboots (with "Run in Debugging Mode" turned on) or the VM simply does not start (with that Debugging box unchecked) and in the log there is an error along the lines of VMware Server unrecoverable error (vmx)

I installed VMware server on my CentOS 5 machine. I had problems getting that working. Then I installed VMware Workstation. That worked fine. Then I tried using VMware server, but apparently VMware Workstation deleted some of VMware Servers files. So, I uninstalled VMware Workstation. Then I tried to reinstall VMware Server, but rpm complains package VMware-server-2.0.2-203138.x86_64 is already installed

I completed the installation of VMWare Server 2.0.2 onto a CentOS 5.4 64-bit distribution. There is a VMware virtual machine file on the server in question, and I want to activate it through the application console.
I did not see anything readily apparent that would facilitate the importing of the virtual machine file. Does anyone have a procedure that can accomplish this task?

I have Linux server with VMware Server 1.0.8. When I creating a virtual machine, I can not "send" a PING to the virtual machine. In the virtual machine, I have installed CentOS 5.3 (32bit). In the virtual machine I have defined the addresses IP. So, whey I can't "sent" a ping to the virtual machie? I have to set something on the Linux server?

I've recently installed CentOS 5, because I needed a good OS to run VMware Server. Just a heads up, I'm not very familiar with RH/CentOS distros, I usually use Arch Linux. My VMware install went fine, config is standard settings. Now I'm trying to access the VMware Infrastructure Web Access using port 8222 (http) and 8333 (https), but it's a no go. I'm connecting from another machine on the LAN, as the CentOS box is headless. I restarted the vmware services, and they seem to be launching fine. I don't know much about VMware though. I verified with netstat and ports 8222 and 8333 are listening.

i am trying to install centos 5.5 x86_64 as a guest OS in vmware server 2.0.2 using netinstall iso. Installation runs fine until the point, when it tries to install selinux-policy-targeted-2.4.6-279.el5.noarch, the whole virtual pc hangs at this.any ideas? i tried to google few things about this, but i have found nothing. this has happened 3 times in row, whole virtual pc always hangs at the same package. i dont have any other problems with vmware, gentoo runs and installs fine in it.i would prefer to do installation using netinstall.iso, it would take a lot of time to download all cds or whole dvd and all i require is a very basic set of packages.

[URL]VMware Workstation 7.0.1 Release Notes has a list of supported OS:[URL]According to that, RHEL 5.4 is listed as supported for both host andguest but CentOS 5.4 is only for guest. This is quite strange and, ifit is true, that could be a serious issue.I succeed to install vmware workstaion 7.1 on centos 5.5, but have run-time error:
[root@ ~]# /etc/init.d/vmware start

I installed CentOS on Vmware server 2.0.2
I took a snapshot of my machine with internet working
If I reboot my machine I lose internet. This makes no sense to me.
I ifconfig eth0 down then ifconfig eth0 up and still no internet
Weird thing
I check ifconfig and my bcast ID is 192.168.2.255 when it is supposed to be 192.168.45.255
(When the internet is working if I check ifconfig the bcast ID is 192.168.2.255)
IF I change my bcast my internet stops working
If I reboot my machine my internet stops working
I checked /etc/sysconfig/network-scripts/ifcfg-eth0 and I see that in my snapshot (where the internet is actually working) the bcast is at 192.168.2.255
Without rebooting if I edit that script and I put it to .45.255 my internet stops working
If I reboot my machine at any time my internet stops working
I have also just realized that I cannot ping my gateway..

I have centos 5.5 on vmware, and I'm trying to boot up from the live cd so that I can fix some issues that I'm having. I have vmware pointing at my cd drive, I mount the cdrom and when I ls, it lists the contents of the cd. But when I go to reboot centos, it doesn't boot from the cd and just boots normally.

Just something that struck me while working on our virtual servers today.
I have bonded 3 NICs at the host in Ubuntu Server 8.04 LTS. They are using mode 0 for Round-robin. Point is to increase the speed/performance of all the servers, but mainly the fileserver. The fileserver is a virtual server running Ubuntu Server 8.04 LTS on VMware Server 2.0.
1) I noticed the NIC in the slave OS reported link speed as 1000 and Im unable to change it as the NIC (virtual one) doesnt support it. Does this not really matter, as the NIC doesnt exist, and it will run at higher speeds anyway? Or do I have to remove the bond on the host, bridge all 3 interfaces from the host to the slave OS, and then make a bond in the slave OS?
2) While at it, does mode 0 only increase performance on data being sent from the host or does it also increase the available incoming bandwidth?
