Maybe this will work. Yet to try.

So it looks like there is a need to add the following to a file named usr.sbin.libvirtd. In commandline, updatedb (sudo updatedb) and then use locate to find that file (locate usr.sbin.libvirtd).

Edit it with gedit or nano or vi or another applicable text editor

Under these lines:

/lib/udev/scsi_id PUx,
/lib/udev/scsi_id PUx,
/usr/lib/xen-common/bin/xen-toolstack PUx,

Add:

/usr/lib/xen-*/bin/pygrub PUx,

Using Virt-Manager 1.2.1 on 14.04. / Xen 4.4 from repos. Cannot create VM machine because this error crops up on virt-manager.

This is after editing /etc/xen/xend-config.sxp to allow virt-manager to work and restarting libvirt and xen services.

Closest clue is from the OpenSuse forums which suggest Apparmor and libvirtd are in conflict. Solution seemed to be to disable Apparmor. Apparmor does not seem installed though.

  Where is the virtual host installed?

  Can you add the exact error message you are getting?

  Sorry, I was not seeing the trees due to the forest. Never mind my last comment.

  Better comment, have you tried this answer? askubuntu.com/questions/466292/virt-manager-cant-connect-to-‌xen

  Thanks. Yes, tried that link. Virt-manager does connect and works passed that point and gets stuck later down the line with above error. In short, didn't help.

  It appears to be a permission issue. Others have raised this same issue. Have a look:\n bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1326003 \n forums.fedoraforum.org/archive/index.php/t-288781.html \

  Launchapad link adds a clue that pygrub might not have enough permissions. This is an old 2014 bug. Looks fixed. Maybe another file has been affected the same way?
