Keir, The following 3 patches allow HVM (SVM and VT) guests to be passively profiled using the very latest patches from Renato. These patches apply to 11470. Renato''s patches: http://xenoprof/sourceforge.net oprofile-0.9.1-xen-r2.patch And also a patch not posted FAIK (oprofile-0.9.1-fix-hvm-addr-overlap.patch) which is in the attached tar.bz2 file. hvm_xenoprofile_1.patch - The first

Hi All. I''m trying to use xenoprof in my Xeon machine with PVOPS (3.1.0 kernel) & xen 4.1.1. In the past, I had failed to use the xenoprof in this environment. (1 year ago) While baremetal booting shows the counter object in /dev/oprofile/0 (or 1,2,3) , booting with xen fails to create those objects. Of course, opcontrol command doesn''t work. It only prints

I''m looking into getting Xenoprof to tun in an HVM domain, since we will eventually need a profiler for HVM domains to track down areas of poor performance. (HVMs have poor performance? :) ) Being relatively new to OProfile, Xenoprof, and Xen internals, I would appreciate any pointers, tips, and comments on how to work the implementation. I see three basic areas of work. 1. Implement

Renato, If one creates an HVM domain (say domain 1) and then does echo 1 > /dev/oprofile/passive_domains one then gets the following on the Xen serial console: (XEN) xenoprof.c:143:d0 xenoprof/x86 with autotranslated mode enabledisn''t supported yet (XEN) xenoprof.c:143:d0 xenoprof/x86 with autotranslated mode enabledisn''t supported yet (XEN) xenoprof.c:143:d0

Renato, When I tried running "opcontrol --start" (after previously running "opcontrol --start-daemon") in dom0, I get this error message: /usr/local/bin/opcontrol: line 1639: echo: write error: Operation not permitted and this message in the Xen console: (XEN) xenoprof: operation 9 failed for dom 0 (status : -1) It looks like opcontrol is trying to do this: echo 1 >

Hi, Keir, Currently, HVM guests do not have access to performance counters. So it is not possible to use performance analyzer software such as vtune in HVM guest to analyze programme performance. Other usage of performance counters , for example, the NMI watchdog, won''t function either. This patch will enable performance counters in HVM guest. Currently, only Core 2 Duo is implemented.

Hi , I am getting following error when i try to run xenoprof /usr/local/bin/opcontrol: line 1082: echo: write error: Invalid argument Using 2.6+ OProfile kernel interface. Reading module info. Using log file /var/lib/oprofile/oprofiled.log Daemon started. what is this write error ? Any help is really appreciated. -John _______________________________________________ Xen-users mailing list

on the asterisk site, it was stated while ago, how to download stable version. like cvs checkout -r v1-0_stable asterisk-addons zaptel libpri but now it's not their. is stable-version removed from the CVS ? or is their some different procedure ? thank you -- Atif

Hello everybody!!! I really need your help guys, I am using the AGI mode in meetme application, and I want that AGI should wait for an input from the client/user i.e. a digit and then proceed, but I have used that AGI function agi->wait_for_digit(), but no use....my agi just passes, or ignores this function, where AGI should stop here and wait for the input.... .....my extension in my

I am using gentoo Linux and Asterisk CVS-HEAD-09/23/04-19:57. I have tested both KPhone and IaxComm for linux but receiving no audio from asterisk. sound is working fine, as I can listen playing files using PLAY or APLAY. KPhone is configured with DTMFmode=inband and codec is ulaw and IaxComm is configured with ilbc if somebody can sort out this Thank you regards, -- Atif

I am configuring a sip-phone, receing calls, excellent voice quality. but it does not place calls, please, can some one sort out. here is my debug output, and below that is sip-debug, Jul 16 11:34:32 DEBUG[163850]: Setting NAT on RTP to 0 Jul 16 11:34:32 DEBUG[163850]: Stopping retransmission on 'iiasPlzFribMJMcW' of Response 1: Found Jul 16 11:34:32 DEBUG[163850]: Setting NAT on RTP to

Hello. I am trying to setup Dovecot on an Alpha running FreeBSD 4.10. I am simply trying the imap/pop3 protocols at this time. But with both protocols the log message I get is: pop3-login: fd_send(5) failed: Bad file descriptor dovecot: child 275 (login) returned error 89 or imap-login: fd_send(5) failed: Bad file descriptor dovecot: child 275 (login) returned error 89 I have tried

this is from my extensions.conf, the first three patterns are for toll-free numbers, and fourth pattern is for other numbers, where an AGI is called for authentication. now when I dial 011448000664327 if falls into the fourth pattern, where as it should be matched by the first pattern. Any suggestions 1 - exten => _01144800XXXXXXX,1,Dial(${MAG}/${EXTEN:3},45,tT) 2 - exten =>

These patches address issues in the kernel part of xenoprof: * Ill-advised use of on_each_cpu() can lead to sleep with interrupts disabled. * Race conditions in active_domains code. * Cleanup of active_domains code.

Hi, I just added 32GB memory in my system and wanted Xen to see that memory, so enabled PAE in xen0 and XenU. I did a make menuconfig in xen0 and xenU, then did a make in xen-unstable and a make install. Whilebooting this kernel, I get the above error PAE mode mismatch. I looked under xen/include/asm-x86/processor.h has #define X86_CR4_PAE defined and so does cpufeature.h have this defined.
