Enable VPMU on XenServer

[Harden Viers]

Hello,

I have been searching this forum to try to find the step-by-step process to enable PMU/VPMU data on a XenServer system.

I have tried

-Adding "vpmu=1" to the /boot/grub/grub.conf file

-Attempted to change the value of /sys/hypervisor/pmu/pmu_mode from 'self' to 'all,' but the system will not allow me to do so due to permissions issues (even as root)

 

I feel like I must be missing something...

 

Any assistance would be greatly appreciated!

I haven't gotten it to set through grub, but try xen-cmdline.  On my system that was 

 

/opt/xensource/libexec/xen-cmdline --set-xen vpmu=on
