[9.0.0] qemu breaks mac os vm
Description of problem:
Mac OS Monterey vm not able to boot after upgrading qemu to v. 9.0.0; no issue with qemu 8.2.2.
This vm is booted with opencore latest version.
The vm is not able to boot, apple logo is displayed on the screen for a bit, then the vm shutdowns, this is quite strange.
I can't see anything useful in the logs.
Changing machine type from q35-9.0 back to 8.2 doesn't solve the issue.
The vm is booted via libvirt (latest version) and it's not a quite "base" vm, it has multiple passthroughs and other things.
Before testing into details and starting to run base vms to see if it boots,maybe someone can see something wrong or maybe someone has the same issue.
Reverting back to qemu 8.2.2 fixes all the issues and the vm is able to boot again.
No issues with a windows 11 vm and with a kali vm.
I can say that it's not a DSDT issue (a problem I was having in the past was related with DSTD), because injecting the DSDT of the vm started from v 8.2.2 doesn't boot it.

This is the xml of the vm:
