The issue is in the qemuOpenFileAs function in src/qemu/qemu_driver.c
which i

Greetings,
I am running a test automation service which makes use of QEMU/KVM. As the
tests run for few minutes, the time spent booting the OS (Windows) is quite
a waste of resources so I decided to play a bit around the idea of hot
cloning running VMs.
Following an old discussion I found, I proc

Greetings,
I am dumping a guest VM memory for inspection using the command
"virDomainCoreDumpWithFormat" and the created files appear to belong to
root (both user and group).
I have searched around but didn't find any answer. Is there a way to
instruct QEMU to create those files under a different

Sorry again.
The snapshot is an internal one and the machine is running.
The whole thing was set-up by another

Is it due to the fact that the snapshots are internal?
Thank for the help.

Greetings,
due to hardware failure I had to replace my workstation which has a
different CPU. I have a VM with several snapshots and I need to revert to a
specific one.
While reverting to it, I get an error due to unsupported CPU features.
Therefore, I try to edit the snapshot XML through the com

memory dump?
If through virsh I use the QEMU `pmemsave` command, I get the memory
dump in less than one second; is there any way to obtain the same
performance?
Thanks anyway for making libvirt the great tool it is!

I made a couple of tests.
Image A.qcow2:
- 2 Gb file size (the image size is 10Gb)
- OS: Windows XP sp2 installed
I create the image B.qcow2 with A as backing store through
virStorageVolCreateXML():
- 160 Mb file size (image size alway 10Gb)
- OS in the same state as before.

Hello everybody,
I would like to be able to spawn several domains from a given snapshot.
So would I. It's not yet possible from libvirt, but we are getting

Lots of cpu cycles saved once new image versions must be deployed

I played around a bit more with storages, pools and snapshots and I
arrived at one conclusion.
In my case I am talking about:
Directory pools: I am managing only this kind of pools.
qcow2 image files: They may be new and empty, populated with a fresh
guest installation or with a full lifecycle (se

What's basically missing is data flow and representation, you don'
absolutely understand the problematic that realizing a multiplatform
snapshots management raises; but I think that for an API purpose what is
implemented here is completely confusing the developer.
