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.
- Using the transient option in the xml file under disk.
- Making a qcow2 image and run that.
I test the last one but for that i must change my xml file to use the
new image. A little bit better explained: i must detach the old disk and
attach the new one.
So my questions are:
- Is the last one stable?
- whats your experience with the option transient?
- Is the performance when i snapshot the image okay?
- Do you had make experience with transient images?
Thank you very much
P.S. Maybe when you dont understand a sentences ask me. I do my best to
explain it better.
Jens
