CPU hotplugging works on CPU granularity. It's meant as an recover-action for the case of machine-check errors. This feature requires Dom0 support to utilize it. This feature has been almost tested on Intel-CPUs only. Then I downloaded the stable version from xen.org and installed. But since the document is not updated, I don't know the detail method to offline a physical CPU. Can anyone give me the hint?

CPU offline/hotplug: Xen 3= .4 can offline

physical CPUs on CPU-core granularity.
CPU hotplugging works on CPU = granularity.
It's meant as an recover-action for the case
of mach= ine-check errors. This feature
requires Dom0 support to utilize it.
This feature has been almost tested

on Intel-CPUs only.

Then = I downloaded the stable version from xen.org= and installed.
But since the document is not updated, I don't know = the detail method to offline a physical CPU.


Can anyone give me the hint? Thanks very much!
