This also appears to affect Debian VMs created from the package openstack-debian-image. It appears that it starts out in HVM mode and then switches to PV drivers mid-way through boot, manifesting with an untagged OVS port in dom0. If I restart the OVS agent that manages OVS ports in dom0, the tag gets placed properly. By then, it's too late for dhcp and cloud-init, so the VM never gets network or metadata.

I suspect that it's because the flags supplied with the image in glance aren't set properly, but I'm still investigating. I thought I remembered reading that you can set something in glance along with the image to define the target hypervisor and virtualization method.
