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

I use xen 4.0(dom0 is suse11.sp1,2.6.32 x86_64) on Dell R710 with PERC H700 RAID adapter. --Intel(R) Xeon(R) CPU E5620 @ 2.40GHz --8 CPU cores. --Memory 64G --RAID5 4.5T When I dedicated (pin) a CPU core only for dom0 use. (I specify "dom0_max_vcpus=1 dom0_vcpus_pin" options for Xen) I got dom0 kernel panic error(pin-1-5.30.bmp) When I pin 2 core to dom0, the dom0 system can boot up,

I have a xen 4.1.1 with a 3.0.4 linux kernel running on a Supermicro Supermicro X8DTL-iF motherboard with 16GB of RAM. If I run the 3.0.4 kernel on the bare metal dmidecode works fine. If I run it under xen dmidecode fails to work. On other systems with different hardware but identical software dmidecode works correctly under xen. On this hardware with xen 3.4.1 & linux 2.6.18, dmidecode

Recently had passthrough of 2xPCI DVB-T cards and 1xPCIe DVB-S2 card working, the last know config that was *certainly* working was dom0 xen-4.1.1-3.fc16.x86_64 kernel-3.1.0-0.rc7.git0.0.fc16.x86_64 domU kernel-3.1.0-0.rc8.git0.0.fc16.x86_64 Since then I''ve updated xen-4.1.1-6.fc16.x86_64 on dom0 kernel-3.1.0-0.rc9.git0.0.fc16.x86_64 on dom0 and domU and updated all other packages

Hello! I''m investigate strange behaviour of vfb in paravirt domU (centos 5) VNC servers started after creating domain, but information in xenstore appears sometimes after 1-2 minutes after start. Why this happening? And how can i get VNC port immediate after creating of domU? Thank''s. -- Vasiliy G Tolstov <v.tolstov@selfip.ru> Selfip.Ru

Hey, There has been some discussion about EFI and SecureBoot and such. Most of the time I get questions in the form of "How do I get Fedora 17 with Xen to do EFI", I am going to concentrate on Fedora, but I think this applies to other distros too. From my reading (I hadn't actually tried EFI yet), there are two ways to bootup a system: - Using grub2.efi. Grub2 does the EFI API
