Bug#645827: linux-image-2.6.32-5-xen-686: new in 2.6.32-38: running in pv domU, VM is freezed after being restored
Package: linux-2.6
Version: 2.6.32-38
Severity: important
This bug was not present in 2.6.32-35squeeze2.
My setup: 64bit squeeze dom0, 32bit PV squeeze domU.
When kernel 2.6.32-38 is running in the domU, domU cant be saved/restored successfuly.
VM is mostly freezed after restore. VM answers to ping. I can issue ssh commands but
interactive ssh is broken (strange, do not get replys). xm shutdown hangs.
If I add vcpu=2 in vm.cfg, vm is completely frozen, doesnt answer to ping or give ssh access.
I can reproduce on 3 dom0 and all VM on these hosts (all 64bit dom0 + 32bit squeeze domU).
CPUs are P4-era dualcore pentium D.
I cant find anything interesting in xen logs on dom0 (I get the same output for 2.6.32-38 kernel (freezing) or
2.6.32-35squeeze2 kernel (working)). Please ask for other logs/informations... I cant find anything relevant to
include.
Reverting to 2.6.32-35squeeze2 in domU fixes the problem (still running 2.6.32-38 in dom0).
Anyone with a similar setup to confirm or disprove the problem?
