Hi All,
Ever since moving from oVirt 3.1 (with Fedora image-based nodes) to oVirt 3=
.3 (and now 3.3.1) with CentOS 6.4 (now 6.5) nodes, I've been having a seri=
ous problem with our Windows guests. To my knowledge, none of the Linux gu=
ests have ever been affected.
The problem appears when a Windows guest is rebooted. Occasionally this ha=
ppens during maintenance work but more often as a result of Microsoft updat=
es which require a reboot. The most recent batch of these that we allowed =
resulted in something like 35 of 40 Windows guests losing networking.
What we see is that the VirtIO Ethernet Adapter is enabled but shows no evi=
dence of actually being connected to the network. The MAC never appears in=
our switches, etc. The solution is to connect to the guest via console an=
d manually disable, then enable, the NIC. Problem solved.
I've found at least two other references to this issue:
http://forum.proxmox.com/threads/11160-Windows-2008-R2-Server-Standard-Edit=
ion-VIRTIO-NIC-Drivers-dont-work-on-boot (exactly our issue)
http://forum.proxmox.com/threads/16550-Windows-server-2012-blue-screen-virt=
io-win-ethernet-card (similar, though we never see a crash)
Needless to say, this is super annoying. Right now it seems my options see=
m to be:
1. Implement a script to reset the NIC as suggested in the first link.
2. Revert to e1000 but not sure how much that will hurt performance and/or=
whether it will limit us to 1 Gbps throughput.
Has anyone experienced this? Would I likely have better luck on the VirtIO=
list? We've been running VirtIO Ethernet 61.63.103.3000 from virtio-win-0=
.1-65.iso but I just now found 61.65.104.7400 included in virtio-win-0.1-74=
.iso. Perhaps that will help although I don't see anything relevant in the=
changelog.
Thanks,
