Hi Rajil, > I don't seem to have that sysctl on my system. Should i create one? It's there: > # sysctl -a |grep vmm ... > hw.vmm.vmx.cap.posted_interrupts: 1 > hw.vmm.vmx.cap.virtual_interrupt_delivery: 1 The easiest way to disable APIC virtualization is to add this line to /boot/loader.conf and reboot hw.vmm.vmx.use_apic_vid="0" (I got that wrong in the previous email; should have been zero) On a reboot, the above sysctl leaves should be set to 0. later, Peter.
