Re: [Xen-devel] cpuidle and un-eoid interrupts at the local apic

Probably you can use a non-Xen kernel to boot up the system, and then you can 
get the micro-code in cpuinfo.  Thanks!

unfortunately the Xenserver kernel seems to not support reading the microcode, 
at least it is not populated in /proc/cpuinfo.
Andrew, are there any special tricks to get the version out of the Xenserver 
kernel ?

Best regards
