题

What ring does qemu execute in when not tied into an existing hypervisor?

Any more complete documentation on this subject would be appreciated as well.

有帮助吗？

解决方案

QEMU always runs in the user ring, even when tied into a hypervisor.

其他提示

Qemu runs in ring level 3 (User-space) while the hypervisor "KVM" that it uses for hardware-assisted mode runs in run-level level 0 (Kernel-space).
