I wonder to which extend we could lower dom0 memory
According to:
https://wiki.xenproject.org/wiki/Tuning_Xen_for_Performance
Memory If the host has more memory than a typical laptop/desktop system, then do not rely on dom0 ballooning. Instead set the dom0 memory to be something between 1 and 4GB adding dom0_mem=1024M to the Xen command line. 1GB is enough for a pretty large...
IIRC, I couldn't go below 1.6GB (400M was reserved for VM , maybe I should try again with the above tweak to make sure)
