[Xen-users] HVM domU stuck with no state flags

[Igor Pavlikevich <ipavlikevich@xxxxxxxxx>]

Hi all.

Sometimes different HVM guests (but all of them have vcpus>1) stuck with no state flags
#xm vcpu-list w157
Name                           ID  VCPU   CPU State   Time(s) CPU Affinity

w157                           507     0        6      ---      64864.1     0-11

w157                           507     1        0      -b-     34287.3     0-11

or
#xm vcpu-list w221
Name                           ID  VCPU   CPU State   Time(s) CPU Affinity
w221                           571     0        18      ---      26898.9 12-23

w221                           571     1        20      ---      27045.7 12-23

Maybe this is some kind of scheduler bug when running a lot of (50+) guests, e.g. depends on amount of qemu-dm processes on

dom0?

dom0: debian wheezy x86_64/xen 4.1.3, CPU 2xE5-2620
domU: Windows 2008R2
dom0 weight is 1024, all guests - 256 with different cap.
