So, I was attempting to use qemu snapshots with backing stores. The QEMU docs (http://wiki.qemu.org/Documentation/CreateSnapshot) make it sound like you simply point your qemu at the snapshot after it's creation, and you're golden. When attempting this with libvirt, though, it fails. I created a snapshot using the above tutorial. the resulting file is disk.0, and a qmeu-img info on it

Hi, Is it possible to "pivot" to a new image without doing blockcopy or blockpull? I know how to use snapshots and blockpull to create a new image and pivot to using it live, but what I would like to do is to have a VM switch from using imageA.qcow2 to image2.qcow2 while running. I don't see why this wouldn't be possible since some of the existing libvirt tools can do this when

Hi There, I''ve been trying to get this to work for the last couple of days, but found no information on the internet that would help. Essentially, a tap-ctl opencommand with a qcow2 image does not work (error code 2) and produces the following line in syslog: tap-ctl: tap-err:tap_ctl_open: open failed, err -2 I have attached a shell script that reproduces the problem on my machine.
