https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=267023 Bug ID: 267023 Summary: bhyve exit on hlt subtly broken on VT-x Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bhyve Assignee: virtualization@FreeBSD.org Reporter: jhb@FreeBSD.org The VMCS contains a field that is set to 1 to indicate that there is a pending HLT. In this state, vmxrun will still HLT on resume even if, e.g., the RIP has been updated to point to a different instruction. VMMs are required to explicitly clear this field after a VMexit due to a HLT if the processor should resume.
