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? -- Package-specific info: ** Version: Linux version 2.6.32-5-xen-686 (Debian 2.6.32-38) (b...@decadent.org.uk) (gcc version 4.3.5 (Debian 4.3.5-4) ) #1 SMP Mon Oct 3 09:00:14 UTC 2011 ** Command line: root=UUID=fbdc829b-2464-444f-8c9a-4a9b8f49d3da ro quiet root=/dev/xvda ro ** Not tainted ** Kernel log: [ 0.004000] CPU: Trace cache: 12K uops, L1 D cache: 16K [ 0.004000] CPU: L2 cache: 1024K [ 0.004000] CPU: Unsupported number of siblings 2 [ 0.004000] Performance Events: no PMU driver, software events only.
