<!--

Configuration file for virtual host metrics daemon (vhostmd).

A better, less noisy, more minimal configuration file
which doesn't depend on Xen.

Supported metric types are: int32, uint32, int64, uint64, real32,
real64, and string.

A metric's value is set to the output produced by executing its action.

'action' can include the special token NAME, in which case the name of
the vm currently under inspection is substituted for NAME.  Only useful
within the vm element.
