Dear all,
i am a little lost, i tried quite a few things with the snapshots, so far with python scripts I can iterate through the existing machines, take one, make a snapshot and all this.
However, there are 2 problems I can not get around:
1. even when on 3.5.1 I can not delete a snapshot on a running VM, if I understood that correctly this relies on the Live Merge Feature where the code is available in vdsm already but it needs a certain libvirt version !?!? So question here is, can I delete a snapshot or not ? can I use only the rest API not python (excuse me I am not a developer)
I can answer this one at least. For now, Centos 7 is lacking a new enough version of libvirt to support Live Merge (> 1.2.7). The virt-preview repository for Fedora is shipping a newer libvirt. You can check if vdsm will support live merge by executing the following on the host in question: sudo vdsClient -s 0 getVdsCaps | grep liveMerge RHEL 7.1 will be shipping a version with the neccessary backports to support live merge so I imagine Centos 7.1 will pick those up automatically? -- Adam Litke
