I am also affected by this bug.

Attempting to start a VM via the virsh tool results in the following:

steve at sid:~$ virsh start jessierescuelive
error: Failed to start domain jessierescuelive
error: internal error: child reported: Kernel does not provide mount
namespace: Permission denied

I found a work-around that restores the ability to start VMs.
Specifically, I added the following line to /etc/libvirt/qemu.conf :

namespaces = []

Finally, I also noticed that uncommenting the following line in the same
config file does NOT work:

namespaces = [ "mount" ]
