Hello,
Please tell me how to disable EPT of KVM.
Can I disable EPT in BIOS menu? I did not find the option in BIOS menu
of Intel DX58 (+i7) mother board.
Thank you.

Thank you, but...
I used "ept=0" and "ept=1" options but I could not find speed difference.
Can I check that EPT is enabled or disenabled?

Maybe your hardware not support it, you can check it by:
cat /proc/cpuinfo | grep ept

Check /sys/module/kvm_intel/parameters/ept to see if it's enabled after loaded the
modules.

Thank you. I confirmed that EPT is enabled or disenabled.
