Hi, I am using this tool for querying VMX capabilities. http://git.qemu.org/?p=qemu.git;a=blob_plain;f=scripts/kvm/vmxcap;hb=HEAD And it shows as below that pause-loop exiting is not enabled. My kernel is 3.14. secondary processor-based controls Virtualize APIC accesses yes Enable EPT yes Descriptor-table exiting yes Enable RDTSCP yes Virtualize x2APIC mode yes Enable VPID yes WBINVD exiting yes Unrestricted guest no APIC register emulation no Virtual interrupt delivery no PAUSE-loop exiting no RDRAND exiting no Enable INVPCID no Enable VM functions no VMCS shadowing no EPT-violation #VE no What shall I do if I wish to enable PLE? I have also tried this: linux-vsvo:~/code/test # rmmod kvm-intel linux-vsvo:~/code/test # modprobe kvm-intel ple_gap=128 linux-vsvo:~/code/test # cat /sys//module/kvm_intel/parameters/ple_gap 0 But, it does not change the ple_gap, and also, the above script still says PLE is disabled. -Jidong -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
