06:23:58	kashyap	aspiers: Morning, on the SEV experiment on Leap 15.0, I don't know you're getting stuck at the UEFI boot
06:24:36	kashyap	aspiers: We can debug it when you're on. I'm hunkering down for a few hours to investigate something, so will be slow in the morning to respond.

10:33:08	aspiers	kashyap: it's not urgent right now but I would like to get to the bottom of it. If you have any ideas let me know
10:34:06	kashyap	aspiers: Will do. Currently mired in parsing getDomainCapabilities(); /me is slow with it
10:35:14	aspiers	kashyap: parsing how?
10:35:21	aspiers	the UEFI bits?
10:36:31	kashyap	aspiers: Yeah, /me gets a pastebin
10:36:39	kashyap	Maybe you can get me out of the ditch :D
10:37:43	kashyap	aspiers: http://paste.openstack.org/show/755161/
10:38:52	kashyap	Essentially:
10:38:54	kashyap	$> virsh domcapabilities --machine q35 | xpath -q -e "//enum[@name='firmware']/value/text()"
10:38:54	kashyap	# Only available from for libvirt 5.4 or above
10:38:58	kashyap	efi
10:39:08	kashyap	And this one (available for much older libvirts):
10:39:10	kashyap	$> virsh domcapabilities --machine q35 | xpath -q -e "//loader/value/text()"
10:39:13	kashyap	/usr/share/edk2/ovmf/OVMF_CODE.fd
10:46:14	kashyap	aspiers: Ignore the pastebin; just spotted more problems w/ it
10:46:23	aspiers	OK
10:46:46	aspiers	I get Cannot open file '-q' at /usr/lib/perl5/vendor_perl/5.18.2/XML/XPath.pm line 53.
10:46:52	aspiers	my xpath doesn't like -q or -e
10:47:16	aspiers	from perl-XML-XPath-1.13-99.19.x86_64

11:41:56	openstack	Launchpad bug 1836204 in OpenStack Compute (nova) "The allocation of VGPU has race problem" [High,Triaged] - Assigned to Alex Xu (xuhj)
11:41:56	fanzhang	Hey, I recently hit the bug https://bugs.launchpad.net/nova/+bug/1836204, and I was wondering why can't we just delete the mdevs after destroy the guest, and always create new mediated devices when booting instance? Is there any special reason why not clean mdevs up after deleting vms?
11:43:15	openstackgerrit	Kashyap Chamarthy proposed openstack/nova master: libvirt: Parse the 'os' element from domainCapabilities https://review.opendev.org/673790
11:44:10	kashyap	aspiers: Okay, an idea for your problem
11:44:38	kashyap	aspiers: I learnt from Laszlo (OVMF maintainer) in the past that there's a QEMU debug port which captures OVMF error messages
11:44:49	kashyap	aspiers: But, it requires you explicitly adding it in. This waY:
11:45:00	kashyap	<qemu:arg value='file:/tmp/ovmf.fedora.q35.log'/>
11:45:00	kashyap	<qemu:arg value='-debugcon'/>
11:45:00	kashyap	<qemu:arg value='isa-debugcon.iobase=0x402'/>
11:45:00	kashyap	<qemu:arg value='-global'/>
11:45:00	kashyap	<qemu:commandline>
11:45:05	kashyap	</qemu:commandline>
11:45:25	kashyap	aspiers: To your test. (Yes, we're doing QEMU 'commandline' passthrough - because we're debugging)
11:45:30	kashyap	s/test/guest/
11:45:56	kashyap	Then, the error message can be read there
11:46:25	aspiers	I'm not expecting any error though
11:46:30	aspiers	it just stops at the UEFI shell prompt
11:46:38	aspiers	as if that's what was supposed to happen
11:46:49	kashyap	Hmm. What is different in Leap, compared to SLES?
11:46:58	aspiers	It's the same guest image
11:47:02	aspiers	only the hypervisor stack changed
11:47:29	kashyap	aspiers: And previously your host was Ubuntu?
11:47:38	aspiers	what?!
11:47:43	aspiers	wash your mouth out!
11:47:43	kashyap	Hehe
11:47:55	aspiers	heathen
11:47:58	aspiers	;-)
11:48:10	kashyap	aspiers: I'm just trying to understand the env 'before' and 'after'
11:48:11	aspiers	It was working fine on SLES12 SP4, broken on Leap 15.0
11:48:22	kashyap	Ah, okay.
11:48:23	aspiers	which are supposed to be close IIRC
11:48:39	kashyap	Right, Leap is upstream
11:49:38	kashyap	aspiers: How about you try to create a guest from scratch on Leap 15.0?
11:49:57	kashyap	Ideally 'virt-install' + "kickstart" (assuming SUSE has such a concept, too)
11:50:08	aspiers	autoyast
11:50:21	kashyap	Right
11:50:34	aspiers	I think I was writing ks.cfg files in the 1990s though
11:50:42	aspiers	certainly a lot in the early 2000s
11:50:53	kashyap	I just a plain minimal '@core' only
11:51:10	aspiers	autoyast was way more powerful, at least until 2010
11:51:11	kashyap	See the bits after "fkstart" here: https://kashyapc.fedorapeople.org/Create-a-SecureBoot-enabled-VM.bash
11:51:13	aspiers	no idea these days
11:51:23	kashyap	aspiers: You wouldn't believe, 10 years ago I _was_ using SUSE :-)
11:51:30	kashyap	Why wouldn't you believe? It's perfectly believable
11:51:30	aspiers	haha I would
11:51:36	aspiers	many people did
11:51:42	aspiers	especially in the 1990s
11:52:11	kashyap	And my laptop has SUSE chamelon stickers, too
11:52:53	aspiers	:-O
11:53:00	aspiers	you didn't get fired for that?
11:53:05	aspiers	X-D
11:53:30	kashyap	Not to mention: https://kashyapc.fedorapeople.org/geeko-key.jpg
11:55:06	kashyap	aspiers: So back to the problem, I have no other ideas why it's stuck like that. Maybe as an experiment: re-install the image from scratch on Leap 15, _and_ try _that_ image on SLES12 SP4
11:55:27	aspiers	well the image was built in OBS using kiwi
11:55:29	aspiers	not manually
11:55:33	sean-k-mooney	aspiers: at least kashyap uses fedora as his distro on his laptop unlike me...
11:55:34	kashyap	Hmm
11:56:05	aspiers	ah you patched the win key, nice
11:56:14	aspiers	sean-k-mooney: don't tell me, Ubuntu
