You have been subscribed to a public bug:

When using libvirt/XEN nova-compute does not respect the reserved memory
for dom0. Dom0 is skipped in memory calculation in
nova/virt/libvirt/driver.py. I suggest introducing of a new config-
option named "libvirt_xen_ballooning=bool" which represents the usage of
XEN ballooning defaulting to "true" (as this is xen default). If this
value is set to false then dom0-memory is included in calculation of
used memory.
