[Xen-users] Remus crashes

[Darko Petrović <darko.b.petrovic@xxxxxxxxx>]

Hello everyone,

I've managed to configure and start Remus. However, it works only while 
the protected server is not loaded. As soon as I start a 
memory-intensive server application, the stream of Remus messages stops, 
leaving me with an error message. I think the message is not always the 
same, but here is what I've got from the last run:
PROF: suspending at 1289921328.328959
PROF: resumed at 1289921330.903716
xc: error: Error when flushing output buffer (32 = Broken pipe): 
Internal error
tc filter del dev vif1.0 parent ffff: proto ip pref 10 u32
RTNETLINK answers: Invalid argument
We have an error talking to the kernel
Exception xen.remus.util.PipeException: PipeException('tc failed: 2, No 
such file or directory',) in <bound method BufferedNIC.__del__ of 
<xen.remus.device.BufferedNIC object at 0x7f27844df210>> ignored
I have tried to pin one physical core to Domain 0 and another one to the 
protected domain, using vcpu-pin but it doesn't help.
Currently I am running the Xen-unstable tree (last updated 3-4 days 
ago), 2.6.32.25 pv-ops kernel as Dom-0 and 2.6.18.8 as Dom-U, but I had 
a very similar problem with Xen 4.0.0 and 2.6.18.8 as Dom-0.
Any suggestions?

Thanks
Darko
