There is something flakey with the new kernel.
- the opensuse 11.3 host 2.6.34.7-0.7-xen (.82.235 addr) can not contact
2.6.37-39-xen VM (.82.236 addr) from Kernel:HEAD or vice versa - see tcpdump
trace below
- the 2.6.37 VM can also not successfully talk to another 2.6.37 VM.
- the 2.6.37 VM can also not successfully talk to 2.6.32-ubuntu/xen VM.
- the 2.6.37 VM can however contact 2.6.18-xen(debian)
- the 2.6.37 VM can reach Internet hosts.
tcpdump/dmesg in the VM:
00:07 twocups:~ # tcpdump -lni eth0 -Xs0 port 22 and not port 48180
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

Host dmesg and xm dmesg shows nothing of interest.
I have another VM server box where 2.6.37 runs on both the host and inside the
VM. That combination works fine.
