This is regarding: Hosts Become Unresponsive with XenServer 5.6 on Nehalem and Westmere CPUs

Now my question is, how do I know if C-State is enabled via terminal / command line without going to BIOS?

To check the C-State status from CLI type:

xenpm get-cpuidle-states 0

Open in new window

This will give you details of all the C-State status.

To check if extra C-States are enabled, from CLI type:

xenpm get-cpuidle-states | grep total | uniq

Open in new window

This will give you total C-State count as output. If the value is larger than 2 then extra C-States are enabled and have to be disabled from the BIOS. If the value is 2 or less then no extra C-States are enabled.
