[Xen-users] 3.4.2 domU networking fails to recover after glitch

[Tony Lill <ajlill@xxxxxxxxxxxxxxxxxxx>]

A couple of times yesterday, my network hiccuped (something funky on
the switch, a couple of other hosts reported the same thing). While
the dom0 handled it fine, I could not communicate to any of my
domUs. using tcpdump on both eth2 and peth2, I could see them send
packets out, but could not see any of the response packets.

These are the messages that I get around the hiccup

Dec  2 10:52:34 xen kernel: skge peth2: Link is down.
Dec  2 10:52:34 xen kernel: eth2: port 1(peth2) entering disabled state
Dec  2 10:52:36 xen kernel: skge peth2: Link is up at 1000 Mbps, full duplex, 
flow control tx and rx
Dec  2 10:52:36 xen kernel: eth2: port 1(peth2) entering learning state
Dec  2 10:52:36 xen kernel: eth2: topology change detected, propagating
Dec  2 10:52:36 xen kernel: eth2: port 1(peth2) entering forwarding state

I haven't had time to do any serious debugging, but I'm hoping
someones has seen similar problems.
