[PATCH V2 0/5] Reintroduce OVMF support

[PATCH V2 0/5] Reintroduce OVMF support

[Wei Liu]

OVMF (open virtual machine firmware) is used to provide UEFI support for
virtual machines. It was first introduced about a year ago but was disabled due
to compilation problem. Now that the compilation problem is resolved we can
reintorduce it.

OVMF tree can be pulled from
  git://xenbits.xen.org/people/liuw/ovmf.git for-xenbits

[PATCH V2 1/5] libxl: bump LIBXL_MAXMEM_CONSTANT to 2048

[Wei Liu]

When using OVMF we need to have 1MiB of memory in place for firmware.
Without this change we have:

(XEN) HVM128: Loading OVMF ...
(XEN) page_alloc.c:1460:d128 Over-allocation for domain 128: 33025 > 33024
(XEN) memory.c:132:d128 Could not allocate order=0 extent: id=128 memflags=0 (0 of 1)

This is not a fatal error as hvmloader will instead use low memory to
load OVMF, but it's better to eliminate such error.

Changing this constant doesn't necessary increase the total amount of
memory a guest uses because it's just a limit.

[PATCH V2 3/5] tools: support system supplied ovmf binary

[Wei Liu]

From: Ian Campbell <ian.campbell@citrix.com>

Debian Jessie at least contains an ovmf package that includes
/usr/share/ovmf/OVMF.fd. It's also possible that user may want to supply
his/her own ovmf binary.
