Re: [Xen-API] Is the host a Xen Master ??

[Konstantina Chremmou <konstantina.chremmou@xxxxxxxxxx>]

If youâre already connected to the host:

# xe pool-list
uuid ( RO)                : xxxx
          name-label ( RW):
    name-description ( RW):
              master ( RO): xxxx
          default-SR ( RW): xxxx

and then compare the master's uuid from the above output with your host's uuid.

Alternatively:
# xe pool-param-get uuid=yyyy param-name=master

And again compare the output to your host's uuid.
