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.

  • $ ifconfig virbr0
    virbr0 Link encap:Ethernet HWaddr 52:54:00:EB:2D:7B
    inet addr:192.168.122.1 Bcast:192.168.122.255

    My MTU00, so no jumbo frames. Rats!

    Thank you for the suggestion!
