[one-users] Java OCA code dependency

[Shashank Rachamalla]

Hi Carlos,

Thanks for the inputs. I don't think there will any problems with the
current behavior. Is there any way I can get the Host Name for the Host on
which a Virtual Machine is currently running ( given the Virtual Machine ID
) ?

The following is the XML output returned by vm.info().getMessage() for a
particular VM whose ID is 23. I don't see Host information listed anywhere
except in the HISTORY section.

If the VM is running, can the value of vm.xpath("/VM/HISTORY/HOSTNAME") be
considered as the Host Name of Host the VM is currently running on ?
