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 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. So here is what I get when I simply try to create the domain: [2008-05-28 13:55:26 16515] DEBUG (__init_s:1072) XendDomainInfo.create([''vm'',

Hi: There is a code sample in <The Definite Guide to the Xen Hypervisor>, chapter 4, "Using Grant Tables". The code sample is as following: #include <public/xen.h> extern void * shared_page; extern grant_entry_t * grant_table; void offer_page() { uint16_t flags; /* create the grant table*/ gnttab_setup_table_t setup_op;

My kernel crashes every time I shut down dom0 This crash was not happening before I installed the Xen hypervisor Any ideas?

Hi Wei, I ran into the following problem when trying to boot another guest after less than a day of uptime. (the system started 15 guests at boot already which went fine). dom0 is allocated a fixed 1536M. Both host as pv guests run the same kernel, some hvm''s run a slightly older kernel (3.9 f.e.) The are quite some granttable messages in xl dmesg, i also included these and a

Hi, I did a git pull on pv_ops tree this morning and now get a crash when eth0 is started, here is the full boot log: Booting ''Xen 3.4 / Linux 2.6.29-rc6-tip'' root (hd0,0) Filesystem type is ext2fs, partition type 0x83 kernel /xen.gz com1=115200,8n1 console=com1,vga iommu=1 [Multiboot-elf, <0x100000:0x131748:0x8e8b8>, shtab=0x2c0078, entry=0x100000] module

Hi all, I have searched the net and haven''t found a good answer so I hope perhaps someone here can help. I have an IBM x3850 (8863) that I am upgrading from SLES11SP1 to SLES11SP2, and at the same time XEN is being upgraded as part of the distro. The server is used as a Xen host for up to 6 guests. Anyway, the server boots fine with the SLES11SP2 default kernel, and the trace

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

Don't use alloc_vm_area()/free_vm_area() directly, instead define xen_alloc_vm_area()/xen_free_vm_area() and use them. alloc_vm_area()/free_vm_area() are used to allocate/free area which are for grant table mapping. Xen/x86 grant table is based on virtual address so that alloc_vm_area()/free_vm_area() are suitable. On the other hand Xen/ia64 (and Xen/powerpc) grant table is based on pseudo

Grant references for the xenstore and xenconsole shared pages exist, but currently only xenstore uses these references. Change the xenconsole daemon to prefer using the grant reference over map_foreign_range when mapping the shared console ring. This allows xenconsoled to be run in a domain other than dom0 if set up correctly - for libxl, the xenstore path /tool/xenconsoled/domid specifies the
