Hi, I'm having troubles with starting PVH guest when memory < maxmem. Exact crash message:

(XEN) Guest stack trace from rsp=ffffffff81c03b40:
(XEN) Fault while accessing guest memory.
Guest kernel: 4.1.13, guest config attached.
Is there any way around it, or such configuration isn't supported yet?
Or maybe it is possible to increase maxmem later using some trick
(memory hotplug or something)?
