[libvirt] [libvirt-list] question about the commands: domhostname and hostname

Hi all,

I am testing the virsh commands, and I found that these two commands:
 * domhostname
 * hostname

>From the manual of virsh commands:
* hostname
           Print the hypervisor hostname.
* domhostname domain
           Returns the hostname of a domain, if the hypervisor makes
it available

It seems that both of them want to get the host name. What's the
difference between them?

>From the source code, domhostname only is supported for openvz on 0.10.1.
Will this  be only for openvz in the future?

Any idea?

Thanks a lot in advance. -:)
