I've attempted to upgrade a Xen box from 3.1.2 to 3.2.1. Unfortunately
it has been a partial success only. At this point I'm really stuck
with a network problem that affects my HVM machines (Linux PV run
The really odd thing is that everything seems to work properly, except
that the "vif" network interfaces in dom0 seem to have only dropped TX
packets for the HVM domains and 0 RX packets. It seems like something
is broken in the network communication path between the HVM domain and
A second change I made was to use Gentoo for configuration of the
bridge device, rather than the network-bridge script. I did this
already for some other bridges, but these don't have any HVM domains
Also, ipvs (linux virtual server) doesn't seem to work. Although I
cannot yet claim this is caused by the upgrade, it seems likely. Xen was
te only change made before I broke that functionality.
Every configuration, I expect you should know is, I hope, included below:
Anyone know/guessing what's going wrong?
Is there any known problem?
How can I solve this?
How can I diagnose this?
Unfortunally I need my services and I restored my previous backup, so I
don't really have a box handy any more to try out these things.
