Subject Re: qemu-img convert a qcow2 to a qcow2
Date Sat, 08 Dec 2012 00:33:10 GMT
There already is backing qcow2 support. But when cloudstack moves the
template from secondary to primary storage to use as a backing file for all
of your VMs, it does a convert. That strips any snapshots or compression
that an uploader may have been counting on, and is overall slower than just
copying the template.
