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. -:) -- Best Regards -Li

"virsh hostname" will give you the hostname of the hypervisor (host), but "virsh domhostname <domain>" is trying to get the hostname of the specified domain (guest).

It's possible to implement it for some other hypervisors as well, but nobody had the need to, I guess.

Am I right? domhostname is the guest's hostname, however... > I saw virsh also has such a command to get guest's name: > $virsh domname domain-id-or-uuid > ...this is the name of the domain (basically this function converts ID or UUID of the domain to its name).

Qemu support is in the works: https://lists.gnu.org/archive/html/qemu-devel/2012-08/msg03821.html but it's stalled since I couldn't get virtio-serial to work on windows and didn't get a chance to revisit it yet.
