[raisin] Using cirros for tests???

[raisin] Using cirros for tests???

[Gémes Géza]

Hi,

I've sent my last couple of days on trying to make raisin tests run on 
different distributions. Tried Ubuntu 16.04, Ubuntu 14.04, CentOS 7 and 
CentOS 6.8 so far. The tests fail because of different reasons on these 
distributions:

1. bussybox-pv passes on Ubuntu 14.04 and 16.04, it fails on Centos 7 
(there is no bussybox in the default repositories, enabling EPEL might 
be too intrusive), it also fails on Centos6 (I haven't track that down yet)

2. bussybox-hvm fails on all the tried distros. On Ubuntu and CentOS 7 
(all of them have grub 2.0.2) grub fails to find the filesystem with 
stage2 and at boot stops at grub-rescue> with no partitions recognized. 
In addition on Ubuntu 16.04 the lopartsetup script fails to set up the 
partition correctly, which could be quite easily get fixed.

My idea is that instead of trying to fix the tests (and to continue to 
do so for upcoming distro releases) we could start using cirros images 
for the tests.

I'd start transforming the existing tests to use cirros if you agree 
with the proposal.

Cheers,

Geza

We need both pv and hvm tests, because they test different hypervisor
functionalities. But it would be fine to replace our hand crafted VM
filesystem based on busybox with Cirros. In other words, it is fine by
me, but we need both cirros-pv and cirros-hvm tests.

Hi Stefano,

I've started creating the cirros tests. So far have three pv tests: 
separate-kernel, pygrub and pvgrub2. On Ubuntu 14.04 with xen installed 
by raisin the pygrub test fail due to pygrub failure to find a python 
lib, which I'm going to investigate later on. The other two tests pass. 
I'll prepare patches soon.

Cheers,

Geza
