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



Hi Shafi,

       Is there any API call or any other method to detect whether the
host in question is a Pool master or a member of a Xen POOL ?

This question was covered a few days ago... Using python :

session = XenAPI.Session('https://'+self.xcphost)
        try:
            session.login_with_password(user_xen,password_xen)
        except XenAPI.Failure, error:
            msg,ip = error.details

            if msg == 'HOST_IS_SLAVE':
                xcphost = ip
                session = XenAPI.Session('https://'+xcphost)
                session.login_with_password(user_xen,password_xen)

(sample code from https://github.com/tranquilit/TISbackup/blob/master/libtisbackup/backup_xva.py)

     And is there a call to get the host info using  the snapshot (UUID)
of its VMS ?

by host info, do you mean the param-list of the host where the vm is running?

You can get the VM uuid from snapshot uuid using
xe vm-list uuid=$(xe snapshot-param-get param-name=snapshot-of uuid=35e68b3d-cadd-afc6-0f57-833be773b9ba )

Then you can query the resident-on value (at least for running vm)

xe vm-param-get param-name=resident-on uuid=71e1795e-a1fa-16ea-4f22-77048d9c1e02

It shouldn't be too hard to translate this in api calls. And like David told earlier, xapi API doc is your best friend.

Cheers,

Denis

Thanks .
