So, network availability drops out even without unprivileged domains. I'm using default xen configuration, machines are on the same subnet (10.8.6.61 and 10.18.6.60), connected by switch.

Does it matter that Gentoo (in current stable version) uses `ifconfig` and `route` to setup networking and /etc/xen/scripts/network uses iproute2 package? It shouldn't, AFAIK.

One thing that I don't understand is that `ifconfig` shows that eth0 holds its IP address even after xen-br0 has been brought up (and xen-br0 has /32 netmask...):
(lo removed from output)


Are you using DHCP to set the eth0 address? I wander if the drop
outs occur when the lease expires. Have you tried getting
dhclient/dhcpcd to set the address for xen-br0 rather than eth0?

Ian

no, I'm setting it manually via `ifconfig` in init script. Notice the following lines in kernel log:

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

Why is eth0 (the only physical device in xen-br0) getting into disabled state?
