Add a dom0 PVH test, the test to be run is launching a PV guest
(test-debian). Note the PVH dom0 tests are only enabled for Xen >=
4.13.
The runvar difference is:
+test-amd64-amd64-dom0pvh-xl-amd all_host_di_version 2020-02-10
+test-amd64-amd64-dom0pvh-xl-intel all_host_di_version 2020-02-10

Wait a little - I think I have an alternative proposal. Just want to
at least smoke test it before sending out.

Replace the perl locking check with stat(1). Stat is able to fstat
stdin (file descriptor 0) when passed '-' as an argument. This is now
used to check $_lockfd. stat(1) support for '-' was introduced to
coreutils in 2009.
After A releases its lock, script B will return from flock and execute

XEN_DOMCTL_destroydomain creates a continuation if domain_kill -ERESTARTS.
In that scenario, it is possible to receive multiple __pirq_guest_unbind
calls for the same pirq from domain_kill, if the pirq has not yet been
removed from the domain's pirq_tree, as:

Thanks! All patches LGTM, feel free to add my
In 7f49abaa0ff91d6dc1592ea80f10211c52fb03c4
arch replumbing: Replace many $r{arch} with $[g]ho->{Arch}
I accidentally broke this, by not spotting that the perl fragment
did not call selecthost and has no $ho.
Fix this as follows:
* Pass all of the -try-append arguments to the perl rune.
*
This only worked in production by accident (most of the production
stuff edits PERLLIB earlier in the invocation sequence).

We currently have a bug where this fails, producing this output:
+ arch=
+ case "$arch" in
+ echo 'Arch not supported for memdisk tests'
Arch not supported for memdisk tests
+ exit 0
It should fail in this case.
