So I notice that some operations by libvirt such as creating a snapshot actually change the source of the active disk image for a domain without requiring a restart of the vm. How can this be achieved manually? There are instances where I am manipulating files with qemu-img or virsh commands and afterward need to change what file the vm is using as its disk. One example is when deleting a

Hi Eric, Thanks for the info. I see the value in this, but it isn't quite what I was looking for. Basically what I want to do is to switch between snapshots quickly. For instance, I am currently working on designing a HA SQL implementation with failover. So right now I have 5 VM's running postgresql as a replication group. I am trying a lot of different things and often have to take a

Hi, Sorry about top-posting, didn't know it was a nuisance. As for developing, I wish I could but I have never spent any time coding in c, c++, etc. I am a systems guy, not a developer, so I only work with scripting languages. I would love to have the tech chops to contribute though. If I have a chance I will look through the relevant code and see if there is anything that I can do,

Just a hunch but is the binary that creates the dump suid? You may want to check the perms on it. Not sure if it is libvirtd or some other binary.

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
