Hey at all, thank you very much Michal Privoznik, Eric Blake and Michal Privoznik for the fast answer :) and your opinion. I try out the snapshot method over the weekend. So have a nice Weekend :) On 11.09.2015 16:36, Daniel P. Berrange wrote:

Hey at all,
my Name is Jens-Uwe Sperling. Iám a young student in computer science. I want install a VM for testing at home.
i had install a VM with virt-install and the default parameters. (Number cpu, mem etc.)
After that i install my OS and configure it.
Now i want work on this image in a transient way. So i can use the OS with the given config but every change i do from now should not change my image.
I found three ways to do that:
- Make a snapshot from my image and kill the snapshot after using. Yes, this will work perfectly.
- Using the transient option in the xml file under disk. Wow, I didn't even know we have such element. Don't expect it to actually work with QEMU though :-)
if (disk->transient) { virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", _("transient disks not supported yet")); goto error; }
