I don't have to explicitly disable. Like Gleb (correctly) noted in his response, APIC-V is not present on Haswell machines. So, it's disabled by default. $ cat /sys/module/kvm_intel/parameters/enable_apicv N (Side note: I did post the out o/p of the above parameters and more in the SETUP-nVMX.rst notes I pointed above. But, I understand, that document is a bit large :) ) > (for L1 you can't enable these features because they are not emulated) Yes, Paolo clarified this to me on IRC, when I erroneously assumed so.
