[Xen-users] Where is my CPU going?

[Enzo Lombardi <enzinol@xxxxxxxxx>]

Hi all,

I am trying to diagnose a lagging issue on one of my domains.

Right now I have 3 DomU running + Dom0 and lagging is really bad. Even Dom0 responsiveness is really low (sometimes it takes minutes to authenticate over SSH).

I fiddled with sched-credit without success:

                                         ID    Weight

Domain-0                             0   6000    0

dom1                                 12    256    0

dom2                                11    256    0

dom3                                   2    256    0

The bad side is that dom1 is Windows and lagging is causing the kernel/drivers to crash.

The machine is a single Xeon 1260L (4 Cores, 8 threads) with 20GB of RAM.

Any hints?

Thanks
