I read your original message regarding this https://www.redhat.com/archives/rhelv5-list/2012-February/msg00060.html
according to your experiences only upgrading kvm hosts are problematic? so upgrading only guests to 5.8 is maybe fine?
I have had limited time of testing so I'd take this with a grain of salt. After experiencing the NFS problem I rolled all the KVM hosts and guests back to 5.7 kernel and kvm module.
Actually it hit me too. 2 guests on the same hosts went unresponsive. The kernel on the host was not updated but kvm and kmod-kvm was. I try with downgraded kvm and kmod-kvm on the host and downgraded kernel on the guests like you did.
sigh
I upgraded the kernel to kernel-2.6.18-308.1.1.el5 (also latest kvm and libvirt) on my host on Thursday night and have had no issues for more than 2 days.
