Hi all,
I have a strange problem with a few old VMs running with Windows XP (and in
this case a Win2008 R2 Server) that occasionally loose network connectivity.
The tap device shows increasing drops:
tap36 Link encap:Ethernet HWaddr b2:84:23:c0:e2:c0
inet6 addr: fe80::b084:23ff:fec0:e2c0/64 Scope:Link
UP BROADCAST RUNNING PROMISC MULTICAST MTU:1500 Metric:1
RX packets:5816096 errors:0 dropped:0 overruns:0 frame:0

collisions:0 txqueuelen:500
RX bytes:5161769434 (5.1 GB) TX bytes:380415916 (380.4 MB)
I see this kinf of error only with Windows XP. All other VMs running fine. If I
live migrate the VM to another
Node connectivity is restored. Rebooting the VM does not help.
The vServer still uses qemu-kvm-1.2.0, but all recent fixes to rtl8139 have
been backported. The tap device
is also already running with IFF_ONE_QUEUE.
Any ideas?
Thank you,
Peter
