[Xen-devel] [OSSTEST Nested PATCH v8 4/7] Changes on test step of Debian hvm guest install

["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 in
preseed generation.
3. In L1 installation context, assign more memory 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 v8:
1. Update a conventional way to comment out CDROM entry in sources.list.
2. Enable nestedhvm feature only for the nested job.
3. Set nested disk and memroy size to be driven from runvars in
'ts-debian-hvm-install'.
