I have started the run on a fedora-43 VM. I am on commit:
de61484ec39f418e5c0d4603017695f9ffb8fe24 master branch.
The configuration command I used was:
../configure --target-list=x86_64-softmmu --enable-debug --enable-trace-backends=log --enable-slirp
Targets and accelerators
KVM support : YES

I have attached the log file : qemu.log to this email. It is stuck at
the last line :
{"timestamp": {"seconds": 1773164370, "microseconds": 609791}, "event": "RESUME"}
It should be some configuration miss from my end.
Thank you for looking into it.
