RBD/qemu-1.7.0 memory leak with drive_mirror/live-migration

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi *,

I just tried a feature for live-migration via:

drive_mirror -f virtio0 rbd:123123/virtio0 rbd

in a qemu-monitoring-session.
One immediately can see some memory consumption... never getting released again. Additionally the block-job never ends, even after X/X bytes completed. You can cancel the job, memory still occupied, after another try more RSS-memory gets filled.

Same procedure with qcow2 does not need any more memory, and the job gets cleared after completion.

Possibly @Josh: any idea? Logfiles with debug_what=? needed? ;)

Thnx in @vance,

Oliver.
