I have to collect cpuinfo and meminfo from hundreds of machines in preparation of updating our inventory and Xen version. Since we pin cpu and ram for dom0, this mangles the info. Is there way to get the real information? I know that xm top will give me the true RAM, but I need a non-interactive method. Specifically, I need the following real, unobfuscated/hidden info: Total RAM Processor (from

Hi there, I have the lucky task to setup a Xen system. my plateform is a dell 2950 with 16Gb of RAM. I got as far as setting up debian sarge and xen following http://www.debian-administration.org/articles/423 and overcoming some specific difficulties (http://kmuto.jp/b.cgi/debian/d-i-2615.htm & http://wiki.ncsa.uiuc.edu/wiki/Dell_PE1950_NIC_Firmware_Workaround) But, my concern now, while

Hello, I''ve tried to get the CPUFreq plugin of collectd running in dom0. But I mentioned that it isn''t so easy to get a file in sysfs on the rigth place. I know that the value has to come from hypervisor and I''ve seen the code in xenpm. The only value I need is "/sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq" which would create cpufreq.c. Can anyone

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, Sorry if this is a stupid question. I am walking into someone else''s xen install, and don''t have access to the host os at the moment. How do I tell just from a domU (with Ubuntu) if it is PV or HVM. I have looked through the forums and documentation and it seems to be very easy to figure this out from dom0, but unfortunately that isn''t possible at the

Hi, I have a problem with a dom0 which is unable to launch my domU : all my dom0 are Debian Lenny amd64 with Debian kernel 2.6.26-2-xen-amd64 and xen-hypervisor-3.2-1-amd64. Then all domU (PV) are Debian Lenny amd64 too, with vanilla kernel 2.6.29.6. So, this new dom0 can''t launch any domU which are working on an other dom0. Software is same on both dom0, and hardware is near the

Any thoughts on setting breakpoints around hypercalls? ---------- Forwarded message ---------- From: Kip Macy <kip.macy@gmail.com> Date: Dec 26, 2005 12:14 AM Subject: setting breakpoints around hypercalls in a domU causes dom0 to lockup To: xen-devel <xen-devel@lists.xensource.com>, Keir Fraser < Keir.Fraser@cl.cam.ac.uk> Stepping through hypercalls (at the source level, not

Hi, I find that after I use xm mem-set to change the current memory allocation of a dom, the MemTotal in /proc/meminfo will give the current allocation. In my understanding, the balloon driver simply alloc / free pages, so the MemTotal should not be changed. Only the free memory will be affected. In normal linux, the value of MemTotal comes from "totalram_pages" defined in

No one knows about this?! It''s normal for domU in Xen-3.3 to have only 16KB of CPU cache size? Thanks!

Hi, I implemented my own Hypercall in xen. Now I wish my application under dom0 could talk to Xen via my hypercall. Currently, I make a stub in dom0''s kernel, which works as a proxy to forward the request. So, my application first makes a system call to dom0, which then makes hypercall to xen. Is this design necessary? May I call hypercalls from user application under dom0 directly?

hi, --> i have 8cores cpu. but my xenserver is using only one cpu, how to make use of all cpu cores --> machine is having 16G ram but domain0 is having very less memory. is there any way to increase memory for domain0 [root@xenserver-DZONGRI ~]# cat /proc/meminfo MemTotal: 574464 kB MemFree: 111776 kB Buffers: 9500 kB Cached: 117320 kB SwapCached: 100

Hi, How could i know the processor architecture whether this is x86 or x86_64 ? arch returns the architecture of the OS installed on the machine. But what happened when i installed x86 dom0 on x86_64 machine, then arch and #uname -a as well as #xm info all shows. x86, but really the machine is x86_64. Could anybody tell me how i can get the system information that this is x86_64 machine. Is

Hi, I recently subscribed to xen-users asking about a powernow-k8 problem, but in the meantime I am not sure if the users-list was the right place for it. So I decided to repeat my question here ;-) My current config is attached. --- snip --- Hi, I recently installed Xen on my AMD64 for my first time and so far, everything seems to work pretty fine. :-) I tried to enable cpu frequency

Hi, when creating a bigger (> 50 GB) HVM guest with maxmem > memory we get softlockups from time to time. kernel: [ 802.084335] BUG: soft lockup - CPU#1 stuck for 22s! [xend:31351] I tracked this down to the call of xc_domain_set_pod_target() and further p2m_pod_set_mem_target(). Unfortunately I can this check only with xen-4.2.2 as I don''t have a machine with enough memory for

Hi all, Can Xen hypervisor modify HVM domU's Shadow page table, under the dom0's context, like trapped from dom0's hypercall? I think it have to call 2 functions at least: guest_walk_tables() and flush_tlb_all(). Can these 2 functions called in dom0's context? In my test, if hypervisor tries to modify HVM's shadow page table, it will bring down the whole system. I am not

Hi, I have a Dell opt 755 machine and installed Xen 3.3.1. The CPU is core 2 due E6550, which as the vmx flag. However, when I reboot the machine to xen 3.3.1. I can not find vmx in the /proc/cpuinfo. But vms appears in the kernel 2.6.29 (not xen kernel). Can anyone help on how to enable vt in this machine? Thanks.
