Hi all, the throughput measured by netperf differs from time to time. The changeset was xen-unstable.hg C/S 11760. This is observed when I executed a netperf on DomU connecting to a netserver on Dom0 in the same box. The observed throughput was between 185Mbps to 3854Mbps. I have never seen such a difference on ia64. Regards, Hiroya _______________________________________________ Xen-devel

Hi, this patch makes Xen boot with the default dom0_mem value when the given value exceeds available memory, instead Xen panics and reboots. Administrators have a chance to correct dom0_mem (and other parameters if necessary) after Xen is up with default, seeing the warning message. Tested by booting Domain-0.

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

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

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

Hello, I''ve been trying to get xenmon.py and xentrace to work, but I consistently get the following (on a couple of different machines/kernels): kibab kibab # xentrace /root/xentrace.log ERROR: Failure to get trace buffer pointer from Xen (22 = Invalid argument) Did I miss an option that has to be turned on or something? Is there some other setting that I need so that everything

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

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, 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

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

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

Hi All, I am running xentrace on an idle machine (dom0 has 2 cpus). There are 4 cpus in the system > date xentrace -e0x82000 > idle.out date The sampling interval is 25 seconds. However when I format and look at the output, I see the sample time is 761 seconds or something bizarre Looks like the cpu cycles have gone beserk. Any ideas as to what could be happening thanks Prabha
