Public bug reported:

Xen's console is attached to hvc0 in PV guests [1]. If an image does set
it up on its grub configuration, the instance may not boot properly.

Nova could set the os_cmdline for that guest as it is doing for other
hypervisors (for example for LXC), adding the console setup there, so
that libvirt configures the domain properly.
