Apparently the latest version of open source xen 3.3.1 has very little support for guest metrics. Keyword: "xenballoon deamon".

One has to install a bunch of tools in each of the PV guests to get internal metrics from it, and there is even a distro restriction (it only supports redhat for now).

I assume that only the commercial Xen really sticks to the Xen API on the xensource page.

I wonder if there is a documentation about what parts of the Xen API is actually implemented in the current version of Xen, and what not..

Hi all,

I use the python binding of Xen API. I want to query some guest
information, so I have a code like:

# ... open session, login, etc ...
metrics = session.xenapi.VM.get_metrics(vmref)
g_metrics = session.xenapi.VM.get_guest_metrics(vmref)

The first one returns a VM_metrics object successfully. But the second
one gives the following error:


Question: Am I doing something wrong or is "VM_guest_metrics" not
implemented? (If so, why is it there in the API reference 1.0.6??)

I use Xen 3.2.1
