libvirt should have support for CreateServer password

[Victor Galkin]

cactus 2011.2

API 1.1

Create server. Take password from response.

Root cannot login to instance with returned password.

More information is needed as to what hypervisor you're using. If the answer is libvirt then currently this is not supported. I believe it might be supported by XenServer?

[Ilya Alekseyev (ilyaalekseyev)]

Brian, we're using libvirt. Actually seems we have gap between different virt drivers. I checked it, you're right, there is no support for this feature in libvirt driver. But as soon as in OS API spec describe this feature this is definitely bug.

@Ilya: are you actually working on this ? Or should we unassign you to let someone else have a shot at it ?

[Mike Pittaro (mikeyp-3)]

There was some discussion on this during BugSquash day.

The issue goes deeper than just libvirt, since even if the hypervisor
supports instance admin passwords, the mechanics of how that password
is passed into the instance are unclear.

The final path might be through injection, or could potentially depend
on having the correct agent running within the vm.

[Vish Ishaya (vishvananda)]

Agreed. Although a version that can actually set the password for a linux box that could be optionally turned on would at least get us closer to feature parity. We could do it with chroot while we have the filesystem mounted. I think this is particularly nasty, but it at least gives us the option to support it until we get proper support through metadata/config_drive/guest agent.

    Add support for admin_password to LibVirt

    If the config flag --libvirt_inject_password is set, Libvirt now makes
    an attempt to inject the admin_password to instances at startup time.

    Fixes bug 767202
