Thread-topic: [Xen-devel] [HVM][PATCH] Prompt users a proper warning if HVM feature disabled in BIOS
Current Xen prompts a warning message, saying that machine is not a
"hvm-capable" platform if it can not detect "hvm" in xen_caps. This
warning is misleading, especially when CPU is actually hvm-capable but
the feature was disabled in BIOS. This patch detects whether CPU is
hvm-capable during boot and uses this variable to prompt correct warning
message when users try to boot hvm guests.

Tested on the following configurations:
  AMD's AMD-V processor: 32-bit and 64-bit
  Intel's VT processor: 32-bit and 64-bit

Applies cleanly to 11677. Please apply to xen-unstable.hg
