libvirt-3.0.0 When attemping to create a virtual machine I receive the error "error : Failed to switch root mount into slave mode: Permission denied”. I’m attempting to run qemu/libvirt/virt-manager in an Arch Linux lxc container on a Ubuntu 16.04 host. The host uses zfs for its containers. The arch container is set up as a priveleged container. I do already have kvm/qemu/libvirt working in a Ubuntu container. The reason for the arch container is because I want to try a newer version of qemu/libvirt. I’m not finding anything on google about this error message. Any way to get around it?
