As we discussed[1][2] before, in ACS release, by default, there is no live volume snapshot for KVM, due to starting from 6.5, qemu-img can't recognize "-s", which used by CloudStack to backup snapshot. One possible solution, to bring the function back, is to build a separate qemu-img rpm from 6.5 with "-s" support, we can name the rpm as "cloudstack-qemu-img-extra" or whatever, and make sure this rpm won't overwrite anything installed on the system, so that won't break RHEL supportability(if anybody care). The changes we need:
1. Build a RPM with "-s" support 2. Push the RPM to a public repo 3. During KVM agent installation procedure, need to install above RPM after KVM agent installed. This step can be either manually, or automatically. Any comments on above steps?
