You can check
ps ax | grep virt
If it is not there start it… use systemd to make it start on boot
The message says there is a permissions issue
Check your /etc/group file. User Shiela may need to be in
some group. I will go to PC and check what I have.
Can you use virt-manager at all?.. eg on a linux .iso?
When you first start vjrt-manager you get one window.
If you use that to click the menu item ‘New VM’ you get a second popup, and in there you can browse your computer files and select a .iso file. Did you get that far?
There is no problem instslling win from a .iso file. I have done it. I have win7 in virt-manager at the moment.
Sorry I cant do any more from memory. Will have to check
in my PC what my setup is.
