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 TX packets:3878744 errors:0 dropped:13775 overruns:0 carrier: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
