similar to: [PATCH] linux: fix processor handling in presence of external control

Hi, Jeremy Since now the pv_ops domain0 is approaching, we are considering to port the dom0 power management related code, or more specifically, the Cx/Px ACPI info parsing code, to pv_ops domain0 tree, so that people can utilize Xen power management capability (Cx/PX) under pv_ops domain0. This RFC is a draft version for comments. === Overview === Requirement: Xen hypervisor need Cx/Px ACPI

Hello, The following patches are a solution to a problem we have encountered when using the Xen hypervisor: - Need Pxx/Cxx states to save on power consumption when using Xen (we do want those datacenters to consume less power!), - Also need to figure out the Turbo mode so that the scheduler can properly boost a core for CPU bound guests. In essence the Xen hypervisor requires that

Hi, i read the xenpm wiki page, but i cannot use the "p-states". xenpm shows: xenpm cpu id : 0 total C-states : 2 idle time(ms) : 1776034 C0 : transition [00000000000000000000] residency [00000000000000000000 ms] C1 : transition [00000000000000260278] residency

Hi All, I have several Xen virtual machines within logical volumes using LVM2. I did not use disk images for performance reasons. Conventionally, if I want to clone my virtual machines, I have to dd the LV to an image file. But this consumes a lot of time and harddisk space. So, instead of doing that, I want to use losetup and kpartx with my logical volumes, which contain operating systems of

Hi Konrad I encountered a bug when trying to bring offline a cpu then online it again in HVM. As I''m not very familiar with HVM stuffs I cannot come up with a quick fix. The HVM DomU is configured with 4 vcpus. After booting into command prompt, I do following operations. # echo 0 > /sys/devices/system/cpu/cpu3/online # echo 1 > /sys/devices/system/cpu/cpu3/online With
