Hi Julio, I think is sane to update to qemu 4 to keep parity with NEMU and simplify our testing with testing. We have to check how it works and what needs update: -CI Salvador already has PR to move to 3.0 that is looking to show any issue in the CI. -Packages I did a test to build qemu 4.0 with current scripts and most of errors are just mismatch of files that we list on the spec file. I sent PR to fix this The only blocker is Red Hat Stefan: I see that qemu build for rhel fails with: `glib-2.40 gthread-2.0 is required to compile QEMU` are you able to build qemu 4.0 with your rhel systems?

In the meantime, I have created a new branch in kata-container/qemu [1] to test this new version + kata patches. Only two patches were applied: 1. 9p optimizations. 2. vm-templating patch.
