kata-irc-bot<me1007> Hey there! Got some question regarding the qemu-lite inside kata: • The developer-guide has a section on building a custom QEMU  • This is referencing the kata-containers/qemu repo which is archived and seems outdated? • The kata-containers/kata-containers repo contains a set of qemu patches that seem to be the current state of "qemu-lite"? • I've seen some unmaintained Intel work on qemu-lite14:03
kata-irc-bot(<http://*%20Kata%20needs%20[light%20weight%20virtualization](http://events17.linuxfoundation.org/sites/events/files/slides/Light%20weight%20virtualization%20with%20QEMU%26KVM_0.pdf|[1]>, [2], [3]  ) are the kata patches related to this? • The Intel work included a patch to load the ELF kernel directly into QEMU without SeaBios or QVMF for improving boottime. I couldn't find anything related in the kata patch collection, which is probably du14:03
kata-irc-botto the custom pc-lite machine type required by this patch? Thank you!14:03
kata-irc-bot<eric.ernst> Hey Moritz, much of the benefit of qemu-lite was 'upstreamed' into QEMU, so this machine type isn't used at this point. I think that section of the developer guide needs to be updated -- I'm surprised it was in the developer guide still. I'll open an issue and PR later today.14:06
kata-irc-bot<fidencio> And thanks @eric.ernst, for being faster than me. :slightly_smiling_face:14:06
kata-irc-bot<eric.ernst> :slightly_smiling_face:  Let me know if you have other questions, @me1007, happy to help, and sorry about the confusion there!14:07
kata-irc-bot<eric.ernst> There is a virtualization summary here, including brief discussion on QEMU machine types we use today:  https://github.com/kata-containers/kata-containers/blob/main/docs/design/virtualization.md#qemukvm14:08
kata-irc-bot<me1007> @eric.ernst Thanks for the quick reply! Interesting, so nvdimm is used. I believe the "direct guest kernel loading" was never upstreamed into QEMU, by any chance do you know if this a feature on the roadmap of kata?14:13
