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:

Salvador already has  PR to move to 3.0 that is looking to show any issue in the CI.

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

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?

Qemu 4 was released this week, is there a plan to start using this new version in kata containers?

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.



* Memory footprint looks better
