--- Comment #10 from Peter Grehan <[email protected]> --- I used a laptop-class CPU when trying the repro (core i5-8250U). In particular, there is a difference in VT-x features as reported by the L1 guest: VT-x: PAT,HLT,MTF,PAUSE,EPT,UG,VPID vs your system: VT-x: PAT,HLT,MTF,PAUSE,EPT,UG,VPID,VID,PostIntr The one of interest here is that KVM is emulating APIC-virtualization (VID,PostIntr). One thing to try is to disable this feature in the L1 guest. In /boot/loader.conf, put an entry hw.vmm.vmx.use_apic_vid=0 After (re)booting the L1 guest, the status of this parameter can be checked with: # sysctl hw.vmm.vmx.cap.virtual_interrupt_delivery hw.vmm.vmx.cap.virtual_interrupt_delivery: 0 <- should be zero -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "[email protected]"
