[pve-devel] qemu-img convert async

[Alexandre DERUMIER]

hi,

I'm seeing that qemu 2.9 have new flags to make qemu-img convert async

http://git.qemu.org/?p=qemu.git;a=commit;h=2d9187bc65727d9dd63e2c410b5500add3db0b0d


"This patches introduces 2 new cmdline parameters. The -m parameter to specify
the number of coroutines running in parallel (defaults to 8). And the -W parameter to
allow qemu-img to write to the target out of order rather than sequential. This improves
performance as the writes do not have to wait for each other to complete."


Does somebody already have tested it ?  (-W flag)
