Hi all,

while installing Windows 2008 SBS after having limited dom0 memory to 2048MB. 
I get:

xc_map_foreign_batch: mmap failed: Cannot allocate memory
xc_map_foreign_batch error 12

and the domU reboots right after.

When I up dom0 memory to 4096 MB all is fine.

Is this expected behaviour? Or should I expect faulty memory? A memtest shows 
no problems, but I guess these are not conclusive.
