I have done some more experiments and it does work when using a Centos 6.2

I read somewhere there is some sort of compatibility mode for virtio but
could not find how to activate it. Is there a way to make these different
virtio host/guest implementations talk to each other?
They should be compatible.
I noticed in your domain XML the VM has two virtio-net interfaces.
Could that be affecting your mount success?
Did you collect a packet capture inside the guest? (tcpdump -nli eth0
-s0 -w /tmp/dump.pcap)
It would be interesting to understand what the guest sees during the
failed and successful UDP NFS mounts.
Can you be more specific about the mount failure. Is there an error
message? Anything interesting in the guest's dmesg?
Did you collect a packet capture on the host?

Hi all,
I sent a reply earlier but apparently not to this mailing list.
The problem went away after installing the latest software updates on
the openSuSE 11.3 guest. I tried reproducing it from a backup of the VM
running the older kernel but was unable to do this on a openSuSE 12.1
host. To reproduce it I would have had to use the centos 6.2 host but
that would be quite a lot more work to do. So I am leaving the issue now
as resolved. It was probably some earlier bug that was fixed.
Cheers
Erik
