[PATCH OSSTEST] ts-windows-install: bump ram size to 1.75G

[PATCH OSSTEST] ts-windows-install: bump ram size to 1.75G

[Wei Liu]

The recommended size of Windows 7 64bit is 2G, 512MB is probably too
low. Given that all hosts in Cambridge instance have at least 4G ram and
all hosts in colo have at least 8G, we bump Windows ram size to a more
reasonable value.

The value 1.75G is chosen because we might want to test Windows guest
migration in the future. This value should make it possible to do local
migration on 4G machines (512MB Dom0 + 1.75G source guest + 1.75G
incoming guest).

Ignore this. Ian already sent to patch!

Similar to my reply to Ian, but 1.75 + 1.75 + 0.5 is 4.  Where do you
expect Xen to run in this setup?
