Hello, I have a question about the way Xentrace takes a trace. In previous versions of Xen, I took a trace by setting the size of buffers, activating them and writing the information into a file (optional). setsize 20 tbctl 1 xentrace /tmp/xentrace.dat Now I''m using xen-unstable and I see that setsize is already integrated in xentrace command. My question is: does start/stop buffer is

xentrace, setsize and the hypervisor don''t seem to be on the same page. If tracing is not enabled, the hypercall will only allow TBUF_SET_SIZE and TBUF_ENABLE. However, set_size calls TBUF_GET_INFO, and xentrace wants to call TBUF_SET_EVT_MASK and TBUF_SET_CPU_MASK before calling TBUF_ENABLE. I don''t see any reason not to call SET_*_MASK and GET_INFO if tracing is not enabled.

Hi everyone, I''m trying to convert some Xen HVM images to run on VMware ESX, unsuccessfully thus far. I believe the problem is that ESX by default wants the VMs to use SCSI virtual disks, but my HVM VMs are configured to use IDE virtual disks. If you have any experience with this sort of thing, please get in touch. Thanks! Diwaker -- http://floatingsun.net/

Hi, I've made some SAP benchmarks on my Xen system and discovered a huge difference in the performance of a "xened" SAP system compared to a native SAP system. Hence, I tried to figure out what might cause this 'overhead' and run a xentrace (listining to all events). Xentrace produced 24gb data and I converted it to 27gb human-readable data. After I gathered the

Since TRC_MEM is defined as 0x000af000 in xen/include/public/trace.h, TRC_MEM = TRC_SCHED | TRC_VMX. I feel strange about this. I do not think scheduling is a part of memory management. Am I right? If not, please tell me the background TRC_MEM is defined as TRC_SCHED | TRC_VMX. If so, please apply this patch. This patch defines TRC_MEM as an independent event mask. In addition, xentrace

Hi list, I''m using xen 3.0.0 and wonder how to obtain the 6 DOMU scheduling parameters from my DOM0 domain. Sort opposite of the sched-sedf xm sub-command Can someone help me ?

I am trying to learn some more about the way windows does TPR writes, and tried xentrace for the first time. I did ''xentrace --time-interval=5 xentrace.out'' to capture some data, and then ran it through ''xentrace_format'' using the supplied example defs file. I can see some PF_XEN entries with virt=0xFFFE0080 (address of TPR), but I want to know the value being

Hi, I read about RPC interface for xenmon in this presentation: www.xensource.com/files/xs0106_xenmon_brief.pdf Has such interface been implemented yet by anyone?

Hi, All This is a patch for xentrace.c. This routine checks the trace buffer is initialized or not. If not, the trace buffer is initialized by using this patch. This is avoiding following message. ERROR: Failure to get trace buffer pointer from Xen (22 = Invalid argument) This routine is based on the specification of the trace buffer control function trace.c/tb_control(). The function checks

Hi, I am using xen-unstable and interested to trace the hypervisor. In previous versions, I was able to trace it by: setsize 20 tbctl 1 xentrace /tmp/xentrace.dat And these functions don''t exist in xen-unstable. xentrace --help shows that in more recent versions the buffers'' size could be determined as a parameter for xentrace. But I can not find any replacement for

Hello, this patch introduces HVM tracing: one tracing class for both, SVM and VMX. It adds several new trace events. So we can differentiate between them in the xentrace formats file and format each event''s data items appropriately. With this patch the xentrace_format output is much more informative. The previous simple tracing in SVM and VMX is completely replaced. Unfortunately I

Hi, I''m trying to create a new gallery layout. I did the following: o create plugin/foobar.rb in my base directory. o copy plugins/gallerylayouters/default.rb in foobar.rb and make appropriate modifications. For simplicity, lets say my class looks thus: require ''webgen/plugins/gallerylayouters/default'' module GalleryLayouters class Foobar <

Hi, I am trying to correlating performance issue in guest VM with the scheduling trace from Xentrace. User-mode application in guest VM periodically dump APIC ID and RDTSC into trace. I also start Xentrace in Dom0 during the same period. However, I notice that range of TSC values report both trace is completely disjointed. TSC values from Xentrace is always greater than what guest VM see, even

Nice time. # make uninstall ... rm -rf //boot/*xen* ... if somebody use "xen" in kernel name (maybe as suffix), so it will be deleted from /boot/ too. Thanks. Denis.

Dear list, as my Xen3 server is finaly becomming ready for production I was wondering if anyone has written a xen usage monitoring/logging tool? Something like xm top, but with continuose logging to a (rr)database. Or a munin plugin? I can''t remember seeing anything simmilar on the list. BTW: where does xm top get the NETTX(k) and NETRX(k) from? For a munin plugin I''d

Hi, I have read a mail in the mail list about xentrace and xentrace_format. But I am still puzzled on how to use them. Could somebody give me an example about how to use xentrace and xentrace_format. What I have done is that: 1. Root:/# xentrace /var/perftests/xentrace.log Then I use xentrace_format to get what I want 2. cat /var/perftests/xentrace.log | xentrace_format
