[Xen-devel] [OSSTEST Nested PATCH v9 6/9] Changes on test step of Debian hvm guest install

["longtao.pang" <longtaox.pang@xxxxxxxxx>]

From: "longtao.pang" <longtaox.pang@xxxxxxxxx>

1. Increase disk size to accommodate to nested test requirement.
2. Since 'Debain-xxx-.iso' image will be stored in rootfs of L1 guest,
therefore needs more disk capacity, increase root partition size to
10000.
3. In L1 installation context, assign more memory (defined in runvar) to
it; Since it acts as a nested hypervisor anyway.
4. Comment out CDROM entry in sources.list to make HTTP URL entry
available for L1 hvm guest.
5. Enable nestedhvm feature in ExtraConfig for nested job.

Changes in v9:
1. Using 'guest_var' to get nested L1 guest's specific disk size and
specific memory size.
2. Using 'guest_var' to enable or disable nestedhvm feature.
