Unable to Create VMs using virt-manager

I am trying to create some VM using the virt-manager and no matter what I do I am getting this error:

Unable to complete install: 'internal error: guest failed to start: Failure in libvirt_lxc startup: Failed to create /var/lib/libvirt/images/vol.qcow2/.oldroot: Not a directory
'

Traceback (most recent call last):

I have tried to set in /etc/libvirt/qemu.conf the user and group to match my user and group, installed libvirt-glusterfs and it doesn’t work. I am using: libvirtd (libvirt) 7.0.0 and virt-manager v.3.2.0. And this is my machine:

Hello,

please check where you want to save VM disk image. You provide path to a directory not a actual disk file.
Proper path should end with vol.qcow2 in your case.

You need to Change the connection from LXC to KVM/QEMU.
