Hi, Is there any documentation on enabling hypervisor support for both C and P-state control? On xen-unstable and linux-2.6.18-xen.hg, if I enable cpuidle=1 on the xen command line and then run xenpm, I will get output for C-states (shown below) but it complains that "Xen cpufreq is not enabled!" cpu id : 0 total C-states : 2 idle time(ms) : 73264 C0

Two things: 1. I''m not convinced ''xm crash'' is needed - ''xm destroy'' will do this (and if you want a dump, do ''xm dump'' followed by ''xm destroy'') 2. I don''t see the point of the --noreboot option on ''xm dump'' -- I think this command should simply live-dump the specified domain - as

Hi, In the case of linux, crash_kexec() is occured by "sysrq c". In the case of DomainU on xen, Help is occured by "sysrq c" now. So The way of dumping DomainU''s memory manualy is nothing. I fix this issue by the following way. 1. Panic is occured by "sysrq c" on both Domain0 and DomainU. 2. On DomainU, coredump is generated in /var/xen/dump (on Domain0).

Oh, thanks, Niraj. I overlooked this initially, because this code is not implemented in waldi 3.1-2 kernel, but only in 3.3-1. I''ll check it out tonight, as booting a new kernel per remote is a bit too dangerous. This would be exactly what I need. BR, Carsten.

Hi, When I tested pvfb, I got the following warnings. It seems to be caused by checking/setting info->dirty without dirty_lock.

Hi, Does Xen provide support for CPU frequency scaling? If there exists such support, from which version they support it? Otherwise what problems do exist in support frequency scaling in Xen?

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''ve tested this and having a cpufreq that slows down the CPU affects the rate of HTB. My ondemand cpufreq governor scales down the CPU frequency about 40% and this is more or less the slowdown the rate suffers, 40%. Any known way of dealing with this without having to disable cpufreq? Thanks in advance :) Ra?l N??ez de Arenas Coronado -- Linux Registered

Hi, i''m a little bit stuck here with creating a HVM-Windows (w2k3) Guest under Xen 3.1. I''m using ubuntu 7,10 with a 2.6.22.16-xen-patched kernel which seems to be stable for single cpu-linux guests. Cpu is a Q6600 and XD,VT and VT-d is enabled in the bios. When i create the windows guest with ''xm create w2k3 -c" (conf below) I get: "Started domain

This patch adds the ia64-specific code for new Qemu . In addition, some ia64 patches aren''t checked into xen-unstable.hg, so I reversed the related logic temporarily. Once sync with xen-ia64-unstable.hg, the logic will regain automatically. Thanks & Best Regards -Xiantao OTC,Intel Corporation _______________________________________________ Xen-devel mailing list

Modify the cpufreq ondemand governor so that it can get idle and total ticks from the Xen hypervisor. Linux and Xen have different ideas of what an idle tick is, so the Xen values for both have to be returned in the same platform hypercall.
