20:27:59	redkrieg	Hi all, I'm trying to use AggregateTypeAffinityFilter to ensure that instances of only a certain few flavors can be started on hypervisors in the aggregate group. I've set the instance_type property to "SKVM" on the aggregate, made sure the hypervisor was added, and ensured that all other hypervisors are in other aggregates. I then set the property on the flavor of instance_type=SKVM, but when
20:28:05	redkrieg	I launch it, the filter does not seem to remove things other than SKVM. Am I misunderstanding how this filter works?
20:29:50	sean-k-mooney	the filter will not move existing instances form a host aggratate
20:31:12	redkrieg	yeah, I was trying to make a new one, I think I did something stupid though. I just realized AggregateTypeAffinityFilter is not in my scheduler_default_filters. sorry for the noise, will come back if it's still not working after fixing that

20:40:35	klindgren	mriedem, looks like you are tackling some live migration stuff right now? Are you aware of a recently fixed bug, that when a live migration fails, that it leaves the database in a bad state?
20:42:43	klindgren	We had a live migrate that failed after the copy and mem transfer, during the vif spinup on the destination node, because the destination node didn't have the network segment that the vm needed. Which left the live migration operation in a completed status. But the states of the vm totally wrong. Status was Migration percentage was 100, and the host and node in the DB was pointing at the source HV, but the VM was really running on the destinati
20:42:43	klindgren	on HV. So all additional actaions agaisnt the VM failed. UNtil we updated the DB to container the correct HV.

22:03:28	Nick_A	we are launching instances with a public IPV4 (and v6) on one port/interface and a private IPV4 on another port/interface. Is there a way to force the public addresses to always be on eth0 and private on eth1 for example? I'm trying to tweak how cloud-init handles some things but it's difficult not knowing which interface will end up with with IPs
22:05:02	sean-k-mooney	no openstack does not provide any guarentees on nic ordering
22:05:48	sean-k-mooney	we expose the info via the metadta service so that you can use that info to determing which interface is which
22:06:02	sean-k-mooney	you should read up on the device role taging feature
22:06:19	Nick_A	thank you
22:07:25	sean-k-mooney	the other thing you can do is if you are using dhcp you can disabel the gateway on the private netwrok so it never recives a default route.
22:07:47	sean-k-mooney	assuming you jsut want to ensure that you default traffic goves via the public interface
22:08:10	Nick_A	hmm that might help with part of our problem
22:20:01	Nick_A	any idea why metadata would send routes for all /24s in a region? Not just the /24 of the instance's IP.

08:55:36	bhagyashris	Hi all, I am trying to live migrate the instance but getting this error: http://paste.openstack.org/show/753291/ on nova compute side can any one have nay idea about the same?
08:57:12	kashyap	bhagyashris: My first guess from the error is that you don't have enough free RAM.
08:57:44	kashyap	Oh, wait. Thre's also a "length mismatch" error
09:00:14	kashyap	bhagyashris: What distro is this, and what are you rversions of libvirt and QEMU?
09:03:53	openstackgerrit	Lee Yarwood proposed openstack/nova master: libvirt: flatten rbd images when unshelving an instance https://review.opendev.org/457886

09:10:04	stephenfin	o rly?
09:10:18	kashyap	Yeah, checking with Dave from QEMU, he says:
09:10:29	kashyap	< dgilbert> kashyap: So, that's a packaging bug for their virtio rom; they need to pad

09:13:12	kashyap	bhagyashris: So I was told it's a distribution bug, so please file with Ubuntu. (Where the packager needs to pad the ROM with 0 bytes, using `dd`.) thanks, Dave Gilbert for the suggestion.

09:40:02	kashyap	bhagyashris: Also see the guidance here: https://wiki.qemu.org/Features/Migration/Troubleshooting#Length_mismatch:_....:_...._in_.21.3D_.....
09:40:07	kashyap	It does require work from distros.
09:43:02	bhagyashris	kashyap: ok you mean it should install through bistro?
09:43:09	bhagyashris	distro*
09:43:40	kashyap	bhagyashris: I mean, there is an action item for Ubuntu QEMU packager to "pad the ROM" (it's a low-level thing)

11:45:31	NewBruce3	has anyone ever been able to live migrate VMs from CentOS (RDO) with SELinux to Ubuntu (OSA) with AppArmor?
11:50:04	NewBruce	i am convinced there is a way to do it, reading into the libvirt docs, but nothing has worked so far
11:57:52	kashyap	NewBruce: I don't think (read: "I'm pretty sure") you will find official libvirt docs for it :-)
11:58:28	kashyap	If you're trying that, be aware that you might be left holding holding a bag of broken VM parts.
11:58:47	kashyap	s/"holding holding"/holding/
11:59:25	kashyap	NewBruce: But ... if you _did_ succeed (or otherwise) might want to write a public blog post, with your exploits
12:10:06	NewBruce	well you can ask mnaser how he did it ;)
