    Issue setting 'options kvm ignore_msrs=1' for nested 64-bit VMs

    bobbyccie Novice

      Hi,

       

      I am having issues running 64-bit VMs on a nested ESXi 6.7 host running on KVM (Ubuntu 16.04.6 EVE-NG).

       

      I believe the fix is to enable 'options kvm ignore_msrs=1' on the main Ubuntu machine.

       

      I have tried adding 'options kvm ignore_msrs=1' in various places, including:

       

      /etc/modprobe.d/kvm.conf

      /etc/modprobe.d/kvm-intel.conf

      /etc/modprobe.d/qemu-system-x86.conf

       

      But after a reboot I still see:

       

      root@eve-ng:~# cat /sys/module/kvm/parameters/ignore_msrs

      N

       

      I can set it to 'Y' with:

       

      root@eve-ng:~# echo 1 > /sys/module/kvm/parameters/ignore_msrs

       

      root@eve-ng:~# cat /sys/module/kvm/parameters/ignore_msrs

      Y

       

      But it doesn't survive a reboot.

       

      Any suggestions? Thanks

       

      P.S. I am running KVM on Ubuntu 16.04.6 LTS.
