Hi,
I am trying to live migrate blkif devices backed by drbd devices and I
am struggling with a problem for a few days now. The problem is that
after migration, the domU machine cannot load any new programs into
memory. The ssh connection survives migration and I can run programs
that are already in the memory but not something that needs to be loaded
from the disk.
I am currently testing with an almost idle machine and I am triggering
the drive migration after the domain is suspended, in step 2, from:
XendCheckpoint.py: dominfo.migrateDevices(network, dst,
DEV_MIGRATE_STEP2, domain_name).
However, I also tried before the domain is suspended from step 1
(dominfo.migrateDevices(network, dst, DEV_MIGRATE_STEP1, domain_name))
and everything works fine, except that there is the obvious possibility
of loosing some writes to the disk because the domain is not suspended yet.
After migration, when I reattach a console I get this message:
"vbd vbd-769: 16 Device in use; refusing to close"
This is from the blkfront.c backend_changed() function but I cannot
figure out why this error occurs.
From the xend.logs and dmesg on the source and destination attached
bellow I cannot spot any errors. I am using xen 3.0.3.
Any kind of ideas will be greatly appreciated as I am a beginner with
developing and debugging xen.
Thank you very much.
