[Pkg-xen-devel] Bug#701744: [xen] Update to hypervisor 4.0.1-5.6 or linux-image-2.6.32-5-xen-amd64 2.6.32-48 causes networking (VIF) failures
I'm seeing this on debian wheezy, too like Johnny Strom reported.
# uname -a
Linux minerve 3.2.0-4-amd64 #1 SMP Debian 3.2.41-2+deb7u2 x86_64 GNU/Linux
# dpkg -l | grep hypervisor
ii xen-hypervisor-4.1-amd64 4.1.4-3+deb7u1
amd64 Xen Hypervisor on AMD64
The network is configured without "(network-script network-bridge)" in
xend-config.sxp and in /etc/network/interfaces, we have no entry for
eth0 and this (replaced the real values by stars):
auto br0
iface br0 inet static
address *
netmask *
broadcast *
gateway *
bridge_ports eth0
on the dom0, we can see this in kern.log:
May 28 19:09:30 minerve kernel: [613987.529752] vif vif-11-0: vif11.0:
Frag is bigger than frame.
May 28 19:09:30 minerve kernel: [613987.539463] vif vif-11-0: vif11.0:
fatal error; disabling device
May 28 19:09:30 minerve kernel: [613987.550091] br0: port 2(vif11.0)
entering forwarding state
on the console for the VM, I could see this multiple times:
[233721.357648] device eth0 left promiscuous mode
[233721.424093] device eth0 entered promiscuous mode
I don't have further access to this VM. On other VMs where this
happened, I could see this in the logs:
[2601471.852025] TCP: Peer 74.94.211.209:31059/80 unexpectedly shrunk
window 4233113998:4233124218 (repaired)

window 4233113998:4233124218 (repaired)
