Hi,

What are the benefits to run libvirt daemon directly on the host rather
than on a container?

In Yoga's release note, it is said :
"Currently this is only supported for fresh deployments without an existing
nova_libvirt container"

But Also it it is said :
"Adds a kolla-ansible nova-libvirt-cleanup command, which may be used to
clean up the nova_libvirt container. This may be useful if switching to a
host libvirt daemon".

Is switching supported?

I am in ther verge of upgrading from Xena to Yoga and I ma wondering about
this.
- What is the gain to use libvirt daemon?
- Could the switch be done after the upgrade to Yoga?


Regards.
