Thanks for your answer. But what do you mean by "rw disks"? I chmod(ed) a+rw
all images but the issue still exists.
Those are two separate things. One is the Linux permissions over a file,
the other is disk (which doesn't have to be necessary a regular file)
and set of actions guest is allowed to do over it. RO disk contains
'readonly="yes"' in its XML definition in domain XML. If there's
none,
disk is RW. A sourceless disk contains no <source/>, shared disk
contains 'shared="yes"' and so on.
