[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [OSSTEST v6 13/24] distros: support PV guest install from Debian netinst media.
The netinst media are iso images containing a base Debian install and
some (image size dependent) additional tasks.
On x86 the "multiarch" iso flavour contains a Xen capable kernel for
both i386 and amd64 so use that.
This adds support for two classes of ISO, the CD sized ones which are
built nightly and the DVD sized ones which are built weekly.
The images are downloaded using jigdo which sources the majority of
the data from a local Debian mirror, for this reason I have not
worried about the fact that the i386 and amd64 tests are downloading
the same thing (adding a specific download job would require finding
up to 4GB of scratch space for each flight).
The ISOs booted using pygrub which can extract the kernel and initrd
from a ISO image. The resulting guests are also booted with pygrub
since the pv-grub-menu package is not available on the ISO images and
we have pvgrub coverage from the netboot tests.

v4: Support http_proxy in jigdo download
v3:
- Indent jigdo-lite script line to improve readability
- Wrap bootloader_args
- Fetch URL on target, to get a timeout. Use wget since that is arranged to
be present.
- include bootloader in test name.
