[libvirt] Please help confirm this upsream issue
by Zhenfeng Wang 15 Aug '13

15 Aug '13

Hi I just try to verify the bug 828546 with the latest libvirt version on rhel7, and found an issue that the on_crash element on guest's xml didn't support the "rename-restart" events on the upsteam. I discussed this issue with eric before, he said that this feature was implemented by fujitsu first, he didn't backported this and he just backported what upstream does, also he was not sure if Fujitsu implemented the "rename-restart" events either, so can you help me confirm that should we support the "rename-restart" events on the upstream? thanks

[libvirt] [PATCH v4 0/2] libxl: implement some chuncks of the NUMA interface
by Dario Faggioli 14 Aug '13

14 Aug '13

Hi and sorry for being so late at this. :-( This is the leftover of my NUMA series for the libxl driver. Basically, all the patches have been checked in but the one actually building the <topology> capability, which is patch 2/2 of this series. I think I addressed all Daniel's comments about VIR_*ALLOC* and error handling. Patch 1/2 is a bugfix to how the range of available NUMA nodes was being handled in a previous patch (more in the changelog). --- Dario Faggioli (2): libxl: fix node ranges in libxlNodeGetCellsFreeMemory() libxl: implement NUMA capabilities reporting src/libxl/libxl_conf.c | 140 ++++++++++++++++++++++++++++++++++++++++++++++ src/libxl/libxl_driver.c | 14 ++--- 2 files changed, 146 insertions(+), 8 deletions(-) -- <<This happens because I choose it to happen!>> (Raistlin Majere) ----------------------------------------------------------------- Dario Faggioli, Ph.D, http://about.me/dario.faggioli Senior Software Engineer, Citrix Systems R&D Ltd., Cambridge (UK)

[libvirt] Xen Developers Summit 2013, CfP (24-25 October, Edinburgh)
by Dario Faggioli 14 Aug '13

14 Aug '13

== Call for Proposals == We are pleased to announce that the Call for Proposals (CFP) for the first Xen Project Developer Summit is now open! The event is being held in Edinburgh, UK from October 24-25. All submissions need to be submitted by 11:55pm (BST) on August 30th. The Xen Project Developer Summit will feature content for developers, integrators and power users of the Xen Project. We are looking for presentations related to development, such as development proposals, updates on feature development, project updates, etc. We are also looking for insight into best practices in deploying Xen at scale, case studies by Xen users and other topics that large scale users of Xen care about. == Submit a Speaking Proposal == by visiting this URL: http://events.linuxfoundation.org//events/xen-project-developer-summit/prog… == Proposals == The program committee will be looking for presentations and workshops related to working with the Xen Project. Topics related to Xen Development include development proposals, updates on feature development, project updates, discussions and proposals on the architectural evolution of Xen, best practices of Xen development, studies and benchmarks of system characteristics such as performance/scalability/security/ease of use/power consumption, lessons learned, interfacing with other open source projects, making Xen easier to consume by distros, etc. We are also interested in proposals that provide insight into best practices in deploying Xen, case studies by Xen users and other topics that large users and integrators of Xen care about. This includes everything from deploying Xen or its sister projects at scale, best practices for working with Xen, case studies by users of Xen, Xen benchmarks, tips and tricks in securing Xen based clouds, topics related to managing Xen based environments, open source projects that are related to Xen and deliver benefits to Xen users, 3rd party Xen integrations, etc. As a Xen user, a proposal that catches the developers attention, is your chance to spark a debate that will influence what is developed by the Xen Project. In short, if it’s relevant to Xen development, integration and usage we are interested in what you might have to say. == Timeline and Deadlines == You can submit a proposal at any time for Xen Project Developer Summit. Please keep in mind that the deadline is August 30, 2013. == Presentation Types == Presentations should be for 25 or 50 minutes. Chose the length of your submission based on the content that you have. Note that we have been overwhelmed with talk proposals in the past and have thus asked speakers to modify talks to fit into a shorter slot. == Travel Sponsorships == Not sure if you can afford the airfare and lodging to attend the summit? Please don’t let that stop you from submitting your best proposal. We may be making a number of travel sponsorships available for speakers who have useful information to share with the Xen Project community. Regards, Dario -- <<This happens because I choose it to happen!>> (Raistlin Majere) ----------------------------------------------------------------- Dario Faggioli, Ph.D, http://about.me/dario.faggioli Senior Software Engineer, Citrix Systems R&D Ltd., Cambridge (UK)

[libvirt] Using magic ELF notes to export info about QEMU monitor commands
by Daniel P. Berrange 14 Aug '13

14 Aug '13

On another mailing list some folks were discussing how to determine what list of QEMU monitor commands a particular libvirt was written to be able to use. Rich Jones mentioned a thing they are doing in libguestfs using magic ELF notes: > My only suggestion is that we could put the strings into a separate > ELF section to make them easy to pull out of the binary. > > One of our libguestfs contributors did this for the libguestfs daemon > so that it's possible now to examine the daemon and find out what > binaries it runs/requires. He did it using the following macro: > > #define __external_command __attribute__((__section__(".guestfsd_ext_cmds"))) > #define GUESTFSD_EXT_CMD(___ext_cmd_var, ___ext_cmd_str) static const char ___ext_cmd_var[] __external_command = #___ext_cmd_str > > OpenSUSE's spec file has a section to read out the commands and > produce dependencies. It uses objcopy to read out the commands from > the binary: > > objcopy -j .guestfsd_ext_cmds -O binary $RPM_BUILD_ROOT/usr/sbin/guestfsd /dev/stdout | tr '\0' '\n' | sort -u To which I replied > Oooh, that's an interesting approach. It will tell you too much, > in so much that it wouldn't be possible to see that a number of > commands are supported by libvirt, but won't be used with specific > QEMU version. But just having an automated way to extract this > full list would still be pretty useful info. Since, we'd be able > to automatically detect additions between releases. > > So I guess we could take our current code: > > virJSONValuePtr cmd = qemuMonitorJSONMakeCommand("query-block", > NULL); > > and change it to > > QEMU_JSON_CMD(QUERY_BLOCK, "query-block"); > > ... > virJSONValuePtr cmd = qemuMonitorJSONMakeCommand(QEMU_JSON_CMD_QUERY_BLOCK, > NULL); > > with QEMU_JSON_CMD being a macro you use in global context to > define a string constant + the elf section. ----- End forwarded message ----- In fact it would be preferable if you could just do it inline > virJSONValuePtr cmd = qemuMonitorJSONMakeCommand(QEMU_JSON_CMD("query-block"), > NULL); > instead of having the macro call separate, but it isn't clear that you can define ELF sections from inline code like that. Anyway, I'm not planning to implement this, but I wanted to mention this idea in case if motivates anyone else here to have a go at writing this feature idea....
