I was bitten by this issue several times already. It affects me when I want to use an ISO image I have stored in my NAS server, via nfs for example. Since root is squashed, libvirt fails to change the ownership and thus fails to launch the VM. I have to then copy it over to my laptop and then tell libvirt to use that one, which it can chown/chmod to its heart content.
I thought I had filed a bug about this already, maybe against virt- manager, but couldn't find it. I'll take a look at the dynamic ownership setting. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1784001 Title: Libvirt changes ownership (user/group) of my ISO images To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1784001/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
