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.

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,

...012 +0000 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 prote...

Changes from v3: - mini-os configuration files moved into stubdom/ - mini-os extra console support now a config option - Fewer #ifdefs - grant table setup uses hypercall bounce - Xenstore stub domain syslog support re-enabled Changes from v2: - configuration support added to mini-os build system - add mini-os support for conditionally compiling frontends, xenbus -
