Hi All I looked at this page for reference to using virtio drivers on KVM guests. http://wiki.libvirt.org/page/Virtio In the requirements section it is mentioned that we need a virtio compatible guest with kernel >= 2.6.25 One of my guest has this version: [root@localhost ~]# uname -a Linux localhost 2.6.18-164.el5 #1 SMP Thu Sep 3 03:28:30 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux I was still able to use the virtio drivers by enabling the corresponding options in the qemu xml file and also i created a new initrd image file inside my guest using the mkinitrd command as mentioned in the link provided above. My question is , Is it fine to use the virtio drivers with the kernel that i have for my guest or i definitely need to get to kernel version >= 2.6.25 ?

In case of centos you can use 2.6.18 because redhat backported all needed virtio drivers from never kernels.
