Hello,
I have a side question, if you don't mind.
I'm going to implement the checks you were wrote about, but still having some
doubts. What do you think, is it really safe to run "/usr/bin/qemu-img check"
to check an image of a running VM? As I understand, it should be absolutely
safe, as the "check" operation being run without the "-r" parameter doesn't try
to write anything to the file, but I'd prefer to ask this question.
So, is it safe to perform check of the image that is being used by a running VM?
Thanks to all,
Vlad
