Hi,
Firstly, this patch is not ready at all and mostly here for collecting comment

style.
The qdisk backend in QEMU is not supporting indirect grant, this is means that
a request can only support 11 * 4KB = 44KB.

Hi Vijay,
This patch doesn't only do initialization but also destruction of vGIC info.
Although, a part of the domain initialization is done in part in #8 and

I would prefer to see the initialization/destruction in
We should parse the output from splitting function, not the original
string, otherwise the parsed result is wrong.
For example:
vnuma = [ [...,"vdistance=10,20",...],
[...,"vdistance=20,10",...] ]
Before this change, vdistance from node 0 to all nodes (including
itself) was 10 and vdis

Note that the code is constructed such that the fallout is dealt with

Only 4KB allocation was using new_memflags. We should use new_memflags
in for 2MB and 1GB allocation as well because that variable contains
node information.
Without this patch, when creating a HVM guest with vNUMA, because the
node information was not present in the flags passed to libxc, actual
