...s. The specific question will be answered below. --- There are currently two interfaces which allow discovery of libvirts and in turn qemu's capabilities. Both return an XML which describes various aspects of the hosts or VMs capabilities. virConnectGetCapabilities(conn) https://libvirt.org/formatcaps.html The XML returned by this API describes mostly the host itself, the CPU, NUMA topology, security driver support, migration features but also describes guests architectures supported by the guest. In case of the qemu driver the guest section describes some of the aspects and configurations sup...

...or cannot do snapshotting, and disable right from the start the snapshotting support in my application, avoiding to throw errors to the user. After reading from the docs, it seems that libvirt doesn't reports yet this information about the hypervisor in the capabilities XML: http://libvirt.org/formatcaps.html a quick test against libvirt 1.1.3 (qemu 1.6.1) on Fedora 20 seems to confirm (see XML dump below[1]). So, if I'm not mistaken, looks like the only way to test for the support in QEMU is to actually request a snapshot and see what happens. Is this right? If this is correct, I would like...
