kata-irc-bot<fidencio> @salvador.fuentes, @eric.ernst, shall we go for 1.13.0-rc0 release or shall we simply try 1.13.0 and call it the last release ever on 1.x branches?16:58
kata-irc-bot<salvador.fuentes> not sure, do we still plan to merge some pending PRs? if not I think 1.13.0 should be fine17:00
kata-irc-bot<eric.ernst> That was my question.  If there are new features outstanding, I guess rc0 is the cutoff anyway.17:02
kata-irc-bot<eric.ernst> i'm fine in either case.17:02
kata-irc-bot<fidencio> I sincerely don't think we plan to merge pending PRs or anything like that.17:04
kata-irc-bot<fidencio> Everyone seems to be really focused on 2.xsssssssssss17:04
kata-irc-bot<fidencio> Let me go through the open PRs Today, and Tomorrow we can discuss this during the AC meeting17:05

kata-irc-bot<chen.bo> @fidencio @eric.ernst @salvador.fuentes Mind merging the PR that upgrades cloud-hypervisor to its latest release for 1.x? Might be good to have this upgrade for the last kata 1.x release.17:14
kata-irc-bot<chen.bo> The PR should be ready for review and merge: https://github.com/kata-containers/runtime/pull/316217:14
*** sameo has quit IRC17:15
kata-irc-bot<salvador.fuentes> @chen.bo yeah, thanks :slightly_smiling_face:17:18
kata-irc-bot<chen.bo> Cool. Thanks @salvador.fuentes @fidencio.17:18
kata-irc-bot<fidencio> Cool, cool, cool.  A single fix in the CI had to be done in 6 times, on our jenkins side.  I would like to get this opportunity as say a huge thanks to the person who pushed for merging the repos. :-)17:30

kata-irc-bot<wmoschet> is kata KSM throttling supported/enabled on 2.x?19:54
*** fuentess has joined #kata-dev19:55
*** simosx has joined #kata-dev19:55
kata-irc-bot<fidencio> It's not supposed to work with virtio-fs, with that said, there are tests using it.19:58
kata-irc-bot<fidencio> Why?19:58
kata-irc-bot<wmoschet> because I saw some ci scripts able to install the ksm job. I was wondering if it was something I could clean up (in case it was supported on kata 1.x only)20:00
kata-irc-bot<eric.ernst> What is the specific limitation with virtiofs+ksm?20:02
kata-irc-bot<fidencio> something something https://gitlab.com/virtio-fs/qemu/-/issues/1620:17
*** yann-kaelig has joined #kata-dev20:18
kata-irc-bot<fidencio> I got to know about this as we got some folks loudly complaining about this20:19
kata-irc-bot<eric.ernst> AFAIU, it works, but not on _those_ pages.20:28
kata-irc-bot<eric.ernst> I haven't had time, but i'm curious to try KSM w/ virtiofs and see the behavior.20:28
kata-irc-bot<eric.ernst> If we can't dedup the shared pages between virtiofsd/QEMU, I think that's a reasonable limitation.20:29
kata-irc-bot<eric.ernst> You can still dedup some of guest kernel/agent/shim.20:29
kata-irc-bot<eric.ernst> just not the container image, an extra volumes?20:29
kata-irc-bot<fidencio> https://github.com/kata-containers/kata-containers/pull/1599#issuecomment-830244130  So, this is also related to shared pages, right?20:31
kata-irc-bot<eric.ernst> TIL20:32
kata-irc-bot<eric.ernst> The gitlab issue details it well.  Thanks!20:34
kata-irc-bot<eric.ernst> Would be good to follow up w/ Dr David on it.20:37
kata-irc-bot<fidencio> AFAIU there's no news about that.  But, hey, always good to follow up with Dr. Dave.20:42
