Hi,
I want to use kvm as VMM for virtualization, my os is Centos 5.4 and everything is fine when I'm using "2.6.18-164.el5". but for my project I need to compile a kernel so I compile 2.6.31.5 kernel and boot it.
and kvm kernel modules are loaded.

[QUOTE]
[root@localhost boot]# lsmod | grep kvm
kvm_amd 28536 0
kvm 143404 1 kvm_amd[/QUOTE]

I'm using this instructions to install a VM:

[QUOTE]qemu-img create -f qcow ubuntu.img 10G
qemu-kvm -hda ubuntu.img -cdrom ~/ISO/ubuntu-9.10-desktop-i386.iso -boot d -m 512[/QUOTE]

But :(
when I want to install VM on my image file I've got this error
