Hello,

I've been using VirtualBox on a MacBook Pro with an M1 chip for a few months, and I've consistently observed high CPU usage, even when my virtual machine is actively doing anything. This leads to significant heat generation on the host machine.

I recently upgraded to version 7.2.0 Beta 1 (build 169020) for macOS, but the issue persists. It appears that VirtualBox may be stuck in a tight loop or similar, as the guest VM show near-zero usage when monitored (e.g., via top inside the guest).

The VM is running Debian 12, installed using the debian-12.11.0-arm64-netinst.iso.

I couldn't find any existing reports describing this behavior, so I'm opening this issue in case it hasn't been noted yet. Please let me know if you'd like me to gather specific logs or system information to assist in debugging.

Thank you.
