kata-irc-bot2<graham.whaley> @eric.ernst @haoyang - am I correct in thinking much APAC Kata activity happens on WeChat? I wonder, would it make sense to have a slack<->wechat bot duplicating the messages, like we have for the irc bot? Any reason we should/cannot do that - would it cause anybody any inconvinience?09:45

kata-irc-bot2<haoyang> @graham.whaley most of discussions are still at slack, only the performance metrics testing that currently i initiated a wechat group to collect ideas. I am planning to send out a brief note when having clear mind and then will move the discussion to ML and slack.10:00

ktibiHi, is it possible to use QEMU (without KVM) like a hypervisor ? I can't enable nested virtualization on my openstack platform ...12:29
gwhaleyhi ktibi: that would be to use qemu as an emulator, rather than a hypervisor manager I guess. Hmm, I'm not sure - it sounds like maybe it would work, but I expect it would be slow(er) for particularly any device interactions. afaik, nobody has ever tried this with kata before.12:35
ktibigwhaley, It's only for demo or test kata.12:36
ktibiI searched a configuration for use qemu like emulator but nothing found.12:36
ktibiI had hope tha someone show me a config example :p12:37
gwhaleyktibi: in the kata code base, it might be hard to make this happen, as iirc we invoke 'govmm' to spin up qemu, and that is probably pretty hard wired to make a 'real VM'... and probably does not have the option to say 'use emulation instead': https://github.com/kata-containers/runtime/blob/master/virtcontainers/qemu.go#L2312:37
gwhaleySo, I don't think you will find a config setting to make it happen, as we have never done this in kata before12:38
ktibiok thx you. I'll try to enable nested virt on nova ;)12:38
