Hi, Today I finally could activate the logs, so I tried again to save a running guest. When I type "virsh save balance /var/lib/libvirt/images/lol.img", the following output is written in the balance VM log file (/var/log/libvirt/qemu/balance.log):
sh: cannot create /var/lib/libvirt/images/lol.img: Permission denied I tried chmod 777 in target folder, but it made no difference. What user/group/permissions should I use in target directory, where the state file will be saved? Thanks in advance. ;] ----- Att, Bruno Menezes On Wed, Apr 13, 2011 at 9:00 AM, Bruno Lamps <[email protected]> wrote: > Hi, > > Yesterday, I've run this command with cron, so I wasn't able to see if > virsh save worked OK.
