Right, I guess it works with the default toolstack (xl) on jessie,
but you are running with TOOLSTACK=xm?

We could just patch the resource to use this on Debian:

  xentool=$(/usr/lib/xen-common/bin/xen-toolstack)

but I need to check if xm is available in stretch/sid at all.

Another workaround you can use is to rename /usr/sbin/xl
using dpkg-divert so the Xen agent does not find it by default.
