[Xen-users] tsc problems under 3.[12].x

["James Harper" <james.harper@xxxxxxxxxxxxxxxx>]

I'm seeing lots of problems under Windows which I think are related to
wildly different tsc counters.

Ping gives really strange numbers when vcpus > 1, windows updates
download really slowly (1%/hour with vcpus > 1, 1%/second with vcpus =
1), and anything that reports the tsc shows that it jumps around as it
gets scheduled onto different cpu's.

Is there something I can do about this? Is it a problem with my
hardware? It does it on two completely different servers, although both
use AMD cpu's. Is it fixed in a later version of xen?

Thanks

James
