I''ve a problem with managing power consumption on Intel Nehalem CPU. I''ve installed Xen 3.4 on our Dell PowerEdge T610 system on a Ubuntu 9.04 distribution. I recompiled the kernel 2.6.30rc5. Now I can see the c-states of the CPUs but no access to P-states information and the frequency scaling does not work. By the way, if I run the kernel 2.6.28.13 which is the last one

I obtain this error when booting (xen/stable-2.6.31.x|xen/master) on Xen 3.4.2 x86_64 xen_major : 3 xen_minor : 4 xen_extra : .2 I had no errors with the same kernel, version of the day 2010-03-03 To compile the kernel i use this configuration " http://pasik.reaktio.net/xen/pv_ops-dom0-debug/config-2.6.31.6-pvops-dom0-xen-master-x86_64 "

Hello, I have been working sometime now on getting a HVM accepting a PCI card from the host. As was said in the VT-D wiki I bought an ASUS P5E VM DO motherboard (rel 0803) which has the VT-D option in the bios. I want to pass a Hauppauge PVR 500 card to a virtual machine running LinuxMCE. After first trying XEN 3.2.1 which did not enable the "VT-D virtualisation" bit in xm dmesg, i

Hi Team, For a XenServer (5.6 sp2) crash I have got following in the crash logs.

Hi, After yum update on a Cent OS 6.0 IBM x3850 server to Cent OS 6.1, the kernel crashes on boot. I have googlet a little, and find that others have the same problem and there seems not to be a solution yet. The kernel that crashes is 2.6.32-131.21.1.el6.x86_64. If i boot the prior kernel 2.6.32-71.29.1.el6.x86_64 instead it works! Is it advisable to run the server with kernel

clear_IO_APIC_pin() ignores entries that are set to delivery mode SMI. While this seems reasonable if the entry was unmasked, I consider it dubious for masked entries. In Linux, such behavior is benign since when the entry later is being used for some normal interrupt, the old setting is simply overwritten. In Xen, however, ioapic_guest_write() uses the vector field to determine the previous

Hi I am trying to install Windows using HVM but I get an error message that is totally useless and I am unable to figure out what the problem is. I just pulled xen-unstable.hg because nothing else supports my CPU yet.

Hi all, My server is IBM x3850 X5 and use Broadcom UNDI PXE-2.1 v5.2.4 stack. When I choose localboot to boot from the harddisk, the system willnot boot up then still trying to boot from PXE. Several times later the PXE boot procedure is crashed with words as I attached. Does anyone have any good idea? Thanks very much.

Hi H. Peter Anvin, I wanted to thank you for sharing information about PXE, I have used this a lot and I wanted to share something that may be important for you and your readers. I have many different Dell model, they all worked well with PXE booting however not for E5510. I noticed that using "LocalBoot -1 or 0" doesn't work well. What I did use for Latitude E5510 (Bios A06)

I notice for some reason you can no longer get pre- builds from the listed place. Can you point me to a better location? UEFI boot isn't working on my hardware so I'd like to try something newer. It is an IBM x3850 X6 if that's interesting info. ____ *Note: UMDNJ is now Rutgers-Biomedical and Health Sciences* || \UTGERS |---------------------*O*--------------------- ||_//

Dom0 doesn''t need to save/restore ioapic state across S3 suspend/resume, as Xen already does it. The more important is to avoid warnings on some platforms which may have uninitialized RTEs to be weird value (like smi mode) but masked. When dom0 saves those entries and then write back later, it''s easy to trigger Xen''s sanity check from ioapic_guest_write. Signed-off-by

The IRQ handling code requires pcidevs_lock to be held only for MSI interrupts. As the handling of which was now fully moved into msi.c (i.e. while applying fine without, the patch needs to be applied after the one titled "x86: split MSI IRQ chip"), io_apic.c now also doesn''t need to include PCI headers anymore.

Keir: When thinking more about IO_APIC virtualization in Itanium, I got a confuse: How is io_apic.c used in xenlinux (X86)? It looks like all the machine resource of io_apic is handled in xen (xen/arch/x86/irq.c), and the PIRQ based on event channel can be handled by pirq_type in linux/arch/xen/kernel/evtchn.c pretty well? Then what is the function of file io_apic.c? thx,eddie

Hi, Here is the patch fixing crash when apic=debug is used and APIC is not properly initialized. This issue appears during Xen Dom0 kernel boot (git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git, xen/stable-2.6.32.x head), however I think that patch is rather generic and should be applied to mainline kernel (it applies to Linux Kernel Ver. 2.6.35 and Ver. 2.6.32.19 with small fuzz).
