Pretest contains the libvirt testing from Wei (ccd)

One of the libvirt self tests failed:
TEST: virshtest
      !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! 40 
      !!!!!!!!!!!!                             52  FAIL
FAIL: virshtest
[...]
=======================================
1 of 114 tests failed
(1 test was not run)
Please report to libvir-list@redhat.com
=======================================

Which isn't a lot to go on, aside frmo fixing this issue do we need to

Shall we drop "ts-libvirt-build: run libvirt test suite" from pretest for
the time being? It seems a bit orthogonal to the rest of the series anyway.

By inspection I think this one might be:
diff --git a/Osstest/TestSupport.pm b/Osstest/TestSupport.pm
index a6d42bd..ceb4d0f 100644
--- a/Osstest/TestSupport.pm
+++ b/Osstest/TestSupport.pm
@@ -1733,7 +1733,7 @@ sub more_prepareguest_hvm ($$$$;@) {
     }
     my $disks = join ",\t\t\n", map { "'$_'" } @disks;
 
-    my $kernel = $ho->{Toolstack}->{Name} =~ m/xend/ ?
+    my $kernel = toolstack($ho)->{Name} =~ m/xend/ ?
 	"kernel      = 'hvmloader'" : '';
 
     my $cfg = <<END;

Since toolstack() is the function which initialises $ho->{Toolstack} my
hypothesis is that on this path nothing has previously called toolstack(),
something which could well have changed over a rebase at some point. I
could imagine also that ts-{redhat,debian-hvm,windows}-install might differ
in some subtle way here.

I can't explain this one yet.

Calling a method on an undefined value results in a different message,
"Can't call method "create" on an undefined value", so somehow
toolstack($ho) is an actual reference, but an unblessed one. I haven't
figured out how that can have happened yet.

$ cat t.pl
#!/usr/bin/perl -w

use strict;

my $foo = {};

my $baz = $foo->{Bar}->{Name} =~ m/123/ ? "A" : "B";

print "$baz\n";
$foo->{Bar}->create();
$ ./t.pl
Use of uninitialized value in pattern match (m//) at /home/ianc/t.pl line 7.
B
Can't call method "create" on unblessed reference at /home/ianc/t.pl line 10.

Whereas with:
    my $baz = $foo->{Bar} =~ m/123/ ? "A" : "B";
the error is:
    Can't call method "create" on an undefined value at /home/ianc/t.pl line 10.

IOW something about:
    $foo->{Bar}->{Name} =~ m/123/ ? "A" : "B";
causes $foo->{Bar} to be initialised.

IOW I think the fix to more_prepareguest_hvm is going to fix this too.

I'll fold that in, drop the patch which does make test and force push to
osstest's pretest, then I'll kill the current flight.

Ian.

Done. The killed flight was 60184.

Good catch.

The root cause is ts-debian-hvm-install calls host_get_free_memory which
initialises toolstack in the background. It's a trick only used by
debian hvm test case.

And I think your fix is correct.
