Any idea what is going on or how to debug it?
Here are a couple of ideas that would yield more information:
Since the console still works I suggest checking dmesg output inside
the guest. Are there any error messages at the bottom?
No, absolutely nothing in dmesg.
Try pinging the host's IP address from inside the guest. Run tcpdump
on the guest's tap interface from the host and observe whether or not
you see any packets being sent from the guest.
Seems arp requests are still going out, but then don't go in:
17:16:21.202547 ARP, Reply 192.168.123.1 is-at 00:25:90:38:09:cd (oui
Unknown), length 28
17:16:21.538724 ARP, Request who-has squeeze1 tell squeeze3, length 28
17:16:21.539026 ARP, Reply squeeze1 is-at 52:54:00:12:34:11 (oui
Unknown), length 28
17:16:22.200912 ARP, Request who-has 192.168.123.1 tell squeeze3, length 28
rmmod virtio_net inside the guest and then modprobe virtio_net again.
See if network connectivity is restored (remember to rerun DHCP or
whatever, if necessary).
Yep, that makes it work again. But probably is not the real solution ;)
Thanks,
Bernd
