gemini_117sda09:51
gemini_117i found kata support add scsi device at create time , for example:09:54
gemini_117INFO[0004] {"arguments":{"driver":"raw","file":{"driver":"file","filename":"/dev/sda"},"node-name":"drive-ce59ad8ad4e080a2"},"execute":"blockdev-add"}  arch=amd64 command=run container=Foo name=kata-runtime pid=32264 source=virtcontainers subsystem=qmp09:54

ananosHi guys, trying to run kata with firecracker on aarch6413:50
ananosI've made a couple of quick "hacky" changes, to check whether this is feasible -- and I'm stuck at the point where the guest is spawned, but the agent can not communicate with the host13:50
ananosthe exact same setup (if I replace configuration.toml with the -qemu.toml equivalent works as expected13:52

fuentessstefanha, davidgiluk: hi guys, we are getting a weird behavior when trying to run dnf update under a kata-container with virtiofs, have documented the issue here: https://github.com/kata-containers/tests/issues/2008, do you think you can take a look?15:48
stefanhafuentess: Looking...15:49
stefanhaOct 17 23:15:45 virtiofs-test virtiofsd[61195]: lo_lookup(parent=975, name=README;5da8f604)15:50
stefanhaThat filename looks suspicious15:50
stefanhaHmm...the logs show that it continues by creating that file.15:50
fuentessthe issue is kind of weird, because it can be workarounded. Eg. if I first run `dnf update dnf`and then `dnf update` to update all other packages, everything goes well, but if I try to run `dnf update` after the container creation, the command gets hanged15:52
stefanhafuentess: I've replied on GitHub.  It would be interesting to see the /proc/PID/stack of the hung process.15:53
stefanhafuentess: DAX is being used.  The pread64(2) syscall is hanging.  So I guess something happened in the DAX code.15:53
fuentessok, thanks stefanha, I'll post the info15:54
