Hi,
when trying to block migrate a VM from one node to another, the source
VM crashed with the following assertion:
block.c:3829: bdrv_set_in_use: Assertion `bs->in_use != in_use' failed.
Is this sth already addresses/known?
Not that I'm aware of, at least.
Block migration doesn't seem to check whether the device is already in
use, maybe this is the problem. Not sure why it would be in use, though,
and in my quick test it didn't crash.
So we need some more information: What's you command line, did you do
anything specific in the monitor with block devices, what does the
stacktrace look like, etc.?
i was also able to reproduce a "flush_blks: Assertion
`block_mig_state.read_done >= 0' failed." by
cancelling a block migration and restarting it afterwards.
however, how can I grep a stack trace after an assert?
thanks,
peter
