[Xen-devel] kernel BUG at drivers/xen/events.c:1466! whem migrating PVM guest xen4.2/2.6.32-jeremy
Hello again.I have 3 servers, (1 Dell R710, 2 R610) that run the same software and almost identical hardware.
xen4.2 from xen-unstable.hg built yesterday 220.127.116.11 dom0 kernel from jeremys git, built yesterday Lets call the R610s "A" and "B" and the R710 is called "C". I can create guests on A and B and migrate them to A B or C and back. Basically everything works fine with one exception: Migrating a paravirtualized guest, created on C, to A or B. (migrating a hvm guest works.) This is create on A, migrate to C and migrate back to A http://pastebin.com/Q1SG4jQ7 This is create on C and fail to migrate to A http://pastebin.com/2KMh34ck The difference between C and the other servers are: Xeon E5520 2.27GHz CPU, not E5640 2.67GHz (R610) LSI MegaRAID SAS 1078, not LSI MegaSAS 9260 (R610)The kernels and xen.gz have been scp'ed to C from A, xen-unstable.hg patchlevel is identical.
This is probably not a guest issue as it applies to 2.6.39, 3.0.2 and in fact i first realized it when migrating a 2.6.32-33-generic ubuntu-lucid server.
Input would be very much appreciated. with best regards -- Andreas Olsowski Leuphana Universität Lüneburg Rechen- und Medienzentrum Scharnhorststraße 1, C7.015 21335 Lüneburg Tel: ++49 4131 677 1309
