[PATCH] xenconsoled: use grant references instead of map_foreign_range
Grant references for the xenstore and xenconsole shared pages exist, but
currently only xenstore uses these references. Change the xenconsole
daemon to prefer using the grant reference over map_foreign_range when
mapping the shared console ring.
This allows xenconsoled to be run in a domain other than dom0 if set up
correctly - for libxl, the xenstore path /tool/xenconsoled/domid
specifies the domain containing xenconsoled.

[hybrid] : mmap pfn space...
Hi Ian/Stefano,
So, I''m back to using pfn space from maxphysaddr below. Stefano, you
suggested ballooning, but that would be just too slow. There are lot of
pages to be mapped, 4k at a time during guest creation, and I am afraid
ballooning and hypercalls to populate EPT will be pretty slow.
OTOH, there is tons of address space available between max-physaddr and
max pfn in dom0. Stefano,

libxl: introduce XSM relabel on build
Allow a domain to be built under one security label and run using a
different label. This can be used to prevent the domain builder or
control domain from having the ability to access a guest domain''s memory
via map_foreign_range except during the build process where this is
required.
Example domain configuration snippet:
seclabel=''customer_1:vm_r:nomigrate_t''
init_seclabel=''customer_1:vm_r:nomigrate_t_building''
Note: this does not provide complete protec...
