Somehow QEMU x64 stopped working on Rancher Desktop, had to switch to a older version of QEMU...
## Switch Rancher Desktop to older version of QEMU x64
$ cd /Applications/Rancher\ Desktop.app/Contents/Resources/resources/darwin/lima/bin/
$ mv qemu-system-x86_64 qemu-system-x86_64.old
$ ln -s `which qemu-system-x86_64` .
## New Version of QEMU fails to start
$ ./qemu-system-x86_64.old --version
QEMU emulator version 7.1.0
## Old Version of QEMU is OK
$ ./qemu-system-x86_64 --version
QEMU emulator version 7.0.0Running QEMU 7.1.0 with Rancher Desktop fails with HV_ERROR...
