KVM virtualization under RHEL 5.4 beta.

[Adriaansen, Tom (RB-NL)]

When trying KVM 

 

I first had the following errors

 

[root at hostname ~]# /usr/libexec/qemu-kvm -hda /kvm/vm/vdisk.img
-cdrom /kvm/iso/w2k8.iso -boot d -m 1024

open /dev/kvm: No such file or directory

Could not initialize KVM, will disable KVM support

Could not initialize SDL - exiting

 

I solved these:

 

First I set Viirtualization switch in SETUP of my Dell server 2950 to
enable (it sits under CPU ...)

This solved the /dev/kvm error.

The second one (Could not initialize SDL - exiting) had something to do
with X11.

I first started it on the DRAC card, I got the SDL error

Then on a putty session with DISPLAY to my Refection emulator on my PC
with xhost +, it did not work. 

[root at hostname ~]# /usr/libexec/qemu-kvm -hda /kvm/vm/vdisk.img -cdrom
/kvm/iso/w2k8.iso -boot d -m 512

XIO:  fatal IO error 104 (Connection reset by peer) on X server
"145.43.85.106:0.0"

      after 0 requests (0 known processed) with 0 events remaining.

Then I started it on a VNC session and gave the exact same command as
before, and there was the popup window with the install screen of W2K8.

 

So my solution was:

Set Virtualisation to enable in the SETUP of your server

And run the qemu-kvm command from within a VNC session.
