Hi All My guest is a CentOS 5.4 VM: [root at 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 [root at localhost ~]# cat /etc/*release CentOS release 5.4 (Final) I wanted to know if the virtio drivers on this guest are stable. The reason for asking this question is that i found this link:
