libvirt users - Oct 2011 - renaming a domain

Hello,

In my system a VM  with a given domain name is defined and started. At a
certain point I will define and start a new VM, with a different name. I
then want to dispose of the old VM and rename the new one to the old
one. Unfortunately I didn't find any API to do the last  step. Is it
possible to change the domain name of a running VM?

 

Thanks,

 

              Roberto

Not currently, short of migrating the VM twice and using the 
rename-on-migration feature (which ends up creating a new qemu process, 
rather than reusing the existing one).  But the request has been made in 
the past, and if someone were willing to write patches, they would 
likely be accepted.
