Using 3c59x NIC. Kernel log: after calling `wm destroy ttylinux`: Dec 12 20:30:52 zirafa device vif3.0 left promiscuous mode Dec 12 20:30:52 zirafa xen-br0: port 2(vif3.0) entering disabled state Dec 12 20:30:52 zirafa xen-br0: port 2(vif3.0) entering disabled state Dec 12 20:33:23 zirafa xen-br0: port 1(eth0) entering disabled state Dec 12 20:34:23 zirafa xen-br0: port 1(eth0) entering learning state Dec 12 20:34:23 zirafa xen-br0: topology change detected, propagating Dec 12 20:34:23 zirafa xen-br0: port 1(eth0) entering forwarding state ...machine worked ok, I can see messages from cron in syslog... maybe this is the time I tried to press some key in ssh connection to domain0, +/- 1 minute or so: Dec 12 21:12:23 zirafa xen-br0: port 1(eth0) entering disabled state Dec 12 21:13:23 zirafa xen-br0: port 1(eth0) entering learning state Dec 12 21:13:23 zirafa xen-br0: topology change detected, propagating Dec 12 21:13:23 zirafa xen-br0: port 1(eth0) entering forwarding state (login from serial console to see what happens) Dec 12 21:13:31 zirafa login(pam_unix)[7594]: session opened for user root by (uid=0) (network connectivity restored) I have no idea why is there 1 minute delay, according to syslog. Network cable was *not* unplugged. BTW, this is what happens when I unplug cable from eth0 (unplugged at 21:27:50, re-plugged at 21:28:33): Dec 12 21:28:23 zirafa xen-br0: port 1(eth0) entering disabled state Dec 12 21:29:23 zirafa xen-br0: port 1(eth0) entering learning state Dec 12 21:29:23 zirafa xen-br0: topology change detected, propagating Dec 12 21:29:23 zirafa xen-br0: port 1(eth0) entering forwarding state Is it normal? j. ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
