[libvirt-users] Using Virtio drivers with kernal 2.6.18-164.el5

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 ?
Thanks Jatin

My guest is: [root@localhost ~]# cat /etc/*release CentOS release 5.4 (Final) Let me know if i need to provide any more information in this regard. Thanks Jatin On 5/6/2015 11:11 AM, Jatin Davey wrote:

In case of centos you can use 2.6.18 because redhat backported all needed virtio drivers from never kernels. -- Vasiliy Tolstov, e-mail: v.tolstov@selfip.ru jabber: vase@selfip.ru

Thanks Vasiliy, Is there any bug or official communication from red hat on this ? I basically need it as an evidence to show it to my team so that we can go ahead and document this while releasing our product. Thanks Jatin
