Title:
block migration of qcow2 VMs copies all empty space
Status in QEMU:
New
Bug description:
I'm running openstack 2012.1 'icehouse' which, ultimately, calls down
into qemu-system-x86 2.0.0+dfsg-2ubuntu1.10.
I primed the process by copying all necessary base images onto the
destination host. Nonetheless, post-migration instances are much
larger than the original image; the copy duplicated all the empty
space that ought to have remained copy-on-write.
