More OpenSource virtualization

1 Comment

Wow!
I just found Proxmox Virtual Environment (v1.1) which is kind of combination between VMware and OpenVZ.
There is the possibility to run Virtual “chrooted” Appliances and “real” Virtual Machines.
That means, you have your Linux boxes (OpenVZ style) and Windows machines (KVM virtualization).
-> (Almost) NO overhead, when running linux clients (because of chrooted environment)
-> Possibility to run Windows machines, etc., too

Features:
– Out-of-the-box installation (insert CD, [Enter], [Enter], ready)
– Web based management
– Cluster functionality
– Live migration
– Install clients from ISO files (full virtualization)
– Run (OpenVZ) templates (container virtualization)
– Backup / Restore (via LVM snapshots)
– Testing Proxmox VE in VMware
– ….

I think it’s worth to have a look at …

Note: 64bit CPU required; for full (KVM) virtualization, you need Intel VT / AMD-V support.

VMware Server [1.06] on SLES 10 x86_64

OS: SUSE Linux Enterprise Server 10 SP1 (x86_64) [64 bit]

VMware Server [1.06] depends on some 32 bit software:
+ xorg-x11-libs-32bit-6.9.x (should automatically add the other packages, too)
– expat-32bit-2.0.x
– fontconfig-32bit-2.3.x
– freetype2-32bit-2.1.x
– glibc-32bit-2.x
– ncurses-32bit-5.x
– zlib-32bit-1.2.x

Additionally gcc, make, kernel headers, etc. have to be installed to run vmware-config-tools.pl properly.

Howto: Install Win98SE in VMware Server for Linux

Just a short howto for installing Windows 98 SE (R) in VMware Server (1.0.3) for Linux. Although I’m not a big fan of M$, sometimes I have to use it. I.e. my bank does not have any linux software for online banking… whatever.. I had an old Win98SE license at home and that crap of software is quite fast as a virtual machine and as long I don’t have to use too often, stability is not the essential part for me..

Prerequisite: You already have installed VMware Server

Create a new virtual machine and choose Win9x as guest system. As the Win9x cdrom is not bootable, boot with a dos disk and create a partion using fdisk (If you lost your dos disk or you don’t have a floppy drive, you can get an image i.e. at http://www.bootdisk.com).

After rebooting your computer, format drive c: using
format c: /s

Reboot your computer again and ensure that atapi/scsi drivers are loaded so that you can access your cdrom-drive (or image).
Start installation with
Z:\setup.exe /iv

The rest is quite easy – follow the installtion steps in the setup program and install the VMware Tools when your system is up and running.

If you want to enable sound, add a sound device for the virtual machine and install the Sound Blaster PCI 128 (R) driver from the creative labs archive.

VMware / time sync with linux guests

1 Comment

In my default configuration, time was running way too fast in VMware linux guests. After spending hours of searching howto solve the problem, I finally found a few different points that might work as a solution.

Enviroment:
Host: SuSE Linux 10.1
Guest: SuSE Linux 10.1
VMware Server: 1.0.2

  • Install the vmware-tools on the guest.
    Don’t forget to install the kernel-sources if you have to recompile some modules.
  • Insert clock=pit into the guest’s kernel boot options.
    When you’re using grub, it kinda looks like this:
    kernel /vmlinuz root=/dev/sda3 apm=off acpi=off clock=pit
  • Set tools.syncTime = “TRUE” in your virtual machine .vmx-file
    (found on the host machine [default in /var/lib/vmware/..])
    Your guest has to be rebooted to activate this setting.
  • Finally, I had to change a little thing on the host machine:
    Disable powersaved (or powernowd or whatever applies to you)

From that time on, my guests are perfectly in sync with the host’s time.

Note: Nov, 23th 2007: .. or not … time is still too fast on some virtual machines : (

Next thing I tried right now is to add the following lines in /etc/vmware/config:
host.cpukHz = 2200000
host.noTSC = TRUE
ptsc.noTSC = TRUE
Where 2200000 (2,2 GHz) is the max speed of the host cpu.

+ Updated to VMware Server 1.0.4
^^ At first sight, this works perfectly for me : )
