how to find out whether hardware kvm is being used?

hi,

I am trying qemu with hardware kvm but I am not sure is being used. There's no iommu irq activity in /proc/interrupts.

Both processes kvm-irqfd-clean and kvm-pit/28618 are idle.

:'-(

You'd have to know whether your hardware supports it and set it in the kernel. I don't remember which item to look for, but I think it shows up in cat /proc/cpuinfo. There's one for Intel and one for AMD.

Intel CPUs with hardware assisted virtualization advertise vmx. AMD CPUs with hardware assisted virtualization advertise svm.

Load up the virtualization image without loading kvm and see how slow it goes. :^)

World of difference on my machine
