| Thread-topic: | Xen peth0 dropping |
I’ve got a Dell Poweredge 850 setup to do some testing with xen and I notice peth0 just seems to die quite frequently.
I don’t really have to be doing anything for it to happen, no domU’s running no real traffic other than ssh connections.
After this happens bringing eth0/xenbr0 down and up doesn’t help only ifconfig peth0 down and then up seems to restore connectivity.
If I do a tcpdump –i peth0 while it’s down I see no traffic at all.
I setup tcpdump –i peth0 while it was working and eventually it stops with the error:
tcpdump: pcap_loop: recvfrom: Network is down
and in /var/log/messages I find
Mar 12 17:51:09 nlnsrv1 kernel: xenbr0: port 2(peth0) entering disabled state
Does anyone have any suggestions as to what this could be?
I’m testing with Xen3.0.1 on CentOS 4.2.
Thanks
John
