Comment 2 for bug 1877470

I agree that these two options
 - live-migration-permit-post-copy
 - live-migration-permit-auto-converge

are entagled in that an enabled permit-post-copy ignores an enabled auto-converge.

See: https://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py#L1151

a charmed config of this would be nice to capture that.
