Any known conflicts if I run Kata containers and regular VMs on a same host?
Hi folks, I'm trying to run Kata containers and regular QEMU-KVM VMs side by side on one same host. While I'm setting up the test environment, I'd like to check if there are any known conflicts between them? I guess the question is mostly about possible conflicts between QEMU-lite and the vanilla QEMU, when they are running side by side. It seems the community is discussing moving to vanilla QEMU (https://github.com/kata-containers/runtime/issues/1397), but before that happens QEMU-lite is still the default option in releases. Besides hypervisor, could there be other conflicts when we run Kata and full VMs together? Thanks, Xiaoning
Hi Xiaoning, The idea would be just build/distribute the version we pin in our versions.yaml. Even if we move to qemu-vanilla we will modify paths to not have path collisions (users can still use their host qemu but is something we don't test). About conflicts I don't see any problem with it. I use standard VMs and kata in my servers without issues. - Carlos

Thank you Carlos. When you are running Kata and VMs together in your server, do you use vanilla QEMU or QEMU-lite?
