[libvirt] While connecting through xen+ssh, virConnectClose doesn't close the connection
by Alexandru Nedelcu 01 Jul '09

Hi, I'm trying to create a Perl script with Sys::Virt (perl bindings). I'm also using Virsh for testing / experimenting, so this is in no way related to my Perl script (I mentioned it because there might be a sollution that I could use / implement). When connecting to libvirtd using a xen+ssh// connection, it connects, libvirt commands are executing, but on virsh "quit" (or when my script terminates), the connection is blocked. It bothers me because my script doesn't terminate. While running with LIBVIRT_DEBUG=1 I get the following messages: 14:30:51.086: debug : virDomainFree:1893 : domain=0x8791ff8 14:30:51.086: debug : virUnrefDomain:367 : unref domain 0x8791ff8 malcolm 1 14:30:51.086: debug : virReleaseDomain:325 : release domain 0x8791ff8 malcolm 14:30:51.087: debug : virReleaseDomain:337 : unref connection 0x87308a0 3 14:30:51.087: debug : virDomainFree:1893 : domain=0x8791f28 14:30:51.087: debug : virUnrefDomain:367 : unref domain 0x8791f28 Domain-0 1 14:30:51.087: debug : virReleaseDomain:325 : release domain 0x8791f28 Domain-0 14:30:51.087: debug : virReleaseDomain:337 : unref connection 0x87308a0 2 14:30:51.087: debug : virConnectClose:1203 : conn=0x87308a0 14:30:51.087: debug : call:6947 : Doing call 2 (nil) 14:30:51.087: debug : call:7017 : We have the buck 2 0x8796f68 0x8796f68 14:30:51.090: debug : processCallRecvLen:6605 : Got length, now need 28 total (24 more) 14:30:51.090: debug : processCalls:6873 : Giving up the buck 2 0x8796f68 (nil) 14:30:51.090: debug : call:7048 : All done with our call 2 (nil) 0x8796f68 Is this normal?

by "Abel Míguez Rodríguez" 01 Jul '09

Hi, this patch uses "OPERATION_INVALID" error instead "OPERATION_FAILED" error where should be used, also adds a missing capability, defining Xen i686 domains.

[libvirt] [PATCH] logging: remove unused level 0
by Amy Griffis 01 Jul '09

01 Jul '09

Some more logging cleanup. Remove all references to log level 0, and replace with VIR_LOG_DEBUG where appropriate. Also change any hard numbers to the corresponding VirLogPriority and add VIR_LOG_DEFAULT for the starting log level.

[libvirt] Upcoming 0.6.5 release and switching the main SCM engine (to git)
by Daniel Veillard 01 Jul '09

01 Jul '09

A couple of things I wanted to raise. - First we have a release 0.6.5 at the end of the week, so we are in bug fix mode, it would be good if people could make a round of testing of the latest CVS/git version or the snapshot at ftp://libvirt.org/libvirt/libvirt-cvs-snapshot.tar.gz The snapshot generation was proken in the previous months but I fixed it today. - Another point is that we use CVS as the SCM, that's historical, that's what I was used to when I created the project but clearly most people now use the git mirror (or mercurial) to generate their patches. I tried to assert how much git was prevalent, at least for patches embedded within the mail content a large majority are git generated: paphio:~/Mail -> tail -100000 libvir | grep "^diff" | wc -l 268 paphio:~/Mail -> tail -100000 libvir | grep "^diff" | grep -- '-git' | wc -l 182 that doesn't account mails which are attached and base64 encoded but I think it's reasonnable to conclude most of people sending patches generated them out of a git tree. CVS certainly show its age, too ! So my plan would be to switch out of CVS and make git the primary SCM, Jim Meyering is already maintaining the current git tree, so the plan would be to create a new main git tree on libvirt.org based on the existing git://git.et.redhat.com/libvirt.git tree, maybe fixing a couple of things in the process, and desactivate the CVS server after a couple of week grace period. I think once the decision is taken it's better to do it earlier than late, and I'm thinking that this could be done earlier next week if Jim schedule allows and there is no objection. That would allow to manage the set of patches for the following release only under git and not need an SCM transition in the course of preparing 0.6.6 (or 0.7.0). - Speaking of the following release, I'm shooting for a slightly smaller development cycle, in order to be able to push the next version in time for Fedora 12 Beta, this means a new release at the end of July, so only a bit more than a couple of weeks for pushing the changes, I really hope we will be able to include a first version of the ESX driver and Power Hyprvisor, if it's the case I think it will be worth bumping the release name to 0.7.0 . Feedback and opinions welcome, I hope git is not too uncontroversial :-) Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel(a)veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/
