[CentOS-virt] CentOS 6.2 / kvm / Windows XP sp3 guest crashes repeatedly after a few minutes

[Bane Ivosev]

i had the same problem with centos 6.3 on ibm x3650 server. windows xp 
with virtio net just reset with any network load and on host 
/var/log/messages says kernel: kvm: 2889: cpu0 unhandled wrmsr: 0x198 
data 0

found the solution on proxmox forum.

just disable jumbo frames on centos host interface ifcfg and ethernet 
switch.

hope this help someone.
