[Ovirt-devel] Re: [PATCH node] Fix ovirt install/uninstall node scripts so reboot is not necessary

[Perry Myers]

One problem still exists with the 'running vms on the appliance host'...

The current procedure is:

1. Install ovirt-appliance, ovirt-node and ovirt-node-selinux rpms
2. ovirt-install-node stateful
3. create-ovirt-appliance
4. virsh start ovirt-appliance

When the appliance comes up, it will contact the host and will assign it a 
keytab.  However, since libvirt doesn't pick up the keytab until it is 
restarted (and you can't restart libvirtd while the appliance is running) 
you need to:

5. On appliance: shutdown -h now
6. virsh destroy ovirt-appliance
7. service libvirtd restart
8. virsh start ovirt-appliance

Now when the appliance is up again, it can contact the physical host and 
create vms on it since libvirt has the correct keytab loaded.

Once we move to using libvirt-qpid and ovirt-qpid this should go away 
since we won't need libvirt to have a keytab, the qpid interfaces will 
will handle the security for us.
