[pve-devel] [PATCH pve-storage] qcow2 format: enable subcluster allocation by default

[DERUMIER, Alexandre]

Hi Fiona,

Thanks for your tests ! Indeed,don't seem to be a silver bullet for
the classic usecase.

Yes, I wonder it couldn't be set only on linked clones && external
snapshots. 

I'll send a patch for lvmcow2plugin soon, still working on blockdev &&
qemu-server side, it's almost done.
