[libvirt] [PATCH] Fix 'virsh pool-list' locking issue
by Cole Robinson 11 Dec '08

11 Dec '08

Running 'virsh pool-list' seems to deadlock libvirtd. Dan gave me some debugging tips, and I managed to track it down to the poolGetAutostart function. The attached patch fixes the issue. Thanks, Cole

[libvirt] [PATCH] Fix segfault if virtual network has no bridge listed
by Cole Robinson 11 Dec '08

11 Dec '08

The attached patch fixes a libvirtd segfault if we try to call virNetworkGetBridgeName on a virtual network with no bridge in its xml. This occurs if the network hasn't been started as long as the daemon has been running. This patch also cleans up an error path in qemu_conf which was overwriting the error returned by virNetworkGetBridgeName. Thanks, Cole

[libvirt] PATCH 0/5: connection cloning support (WIP)
by Daniel P. Berrange 10 Dec '08

10 Dec '08

This series is a work-in-progress set of patches implementing connection cloning. The idea is that if you want to use a connection form multiple threads, you could do virConnectPtr copy = virConnectClone(conn) and use 'copy' from the other thread. This avoids the problem of having to make all the virError handling stuff thread-local whic is the blocker for allowing real mutlti-thread access to a single virConnectPtr object. I believe this cloning support should be sufficient for the Java bindings need to use a thread for its event loop. The idea being that if you wanted to use an event loop in a background thread, you'd create a cloned object for use event loop triggered callbacks like domain events notifications. I'd still like to do some experiments later making the single virConnectPtr fully thread safe, but that'll take a little more time. I'm hoping this cloning will address the Java needs right now...

[libvirt] F10 rpm problems
by Ben Guthro 09 Dec '08

09 Dec '08

So...I decided to make the leap, and upgraded to F10 (from F9) After my upgrade, I decided to build the libvirt rpm from source, and install it. So far, so good...everything built, and installs nicely. However, when I run virsh, I get the following error: virsh: error while loading shared libraries: libgnutls.so.13: cannot open shared object file: No such file or directory Fedora 10 has /usr/lib/libgnutls.so.26, so I'm not real sure why it is looking for the old F9 versions. I have tried a make clean, make distclean, even re-cloning the repo...without effect. Does anyone have any thoughts as to why it is choosing this version of gnutls?

[libvirt] [PATCH] fix just-broken "virsh start" and "virsh pool-start" commands
by Jim Meyering 09 Dec '08

09 Dec '08

* src/virsh.c (cmdPoolStart, cmdStart): Change hard-coded vshCommandOptDomainBy string argument to match just-changed option name. Cole Robinson reported that "virsh start" was broken and provided that part of the fix. Bug introduced by yesterday's "virsh.c: tweak options to produce more accurate help". * tests/start: New file. Test for the above fix. * tests/Makefile.am (test_scripts): Add start. --- Without this change, "virsh start" and "virsh pool-start" would always fail. I'm fixing this in two steps: first is this patch: make the tiny string-changing fixes (along with the new test). Second will be a more invasive change to make it so the duplicate strings are removed altogether, so they'll never get out of sync again. src/virsh.c | 4 ++-- tests/Makefile.am | 1 + tests/start | 42 ++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 45 insertions(+), 2 deletions(-) create mode 100755 tests/start diff --git a/src/virsh.c b/src/virsh.c index bb81f25..1a5b42f 100644 --- a/src/virsh.c +++ b/src/virsh.c @@ -1021,7 +1021,7 @@ cmdStart(vshControl *ctl, const vshCmd *cmd) if (!vshConnectionUsability(ctl, ctl->conn, TRUE)) return FALSE; - if (!(dom = vshCommandOptDomainBy(ctl, cmd, "name", NULL, VSH_BYNAME))) + if (!(dom = vshCommandOptDomainBy(ctl, cmd, "domain", NULL, VSH_BYNAME))) return FALSE; if (virDomainGetID(dom) != (unsigned int)-1) { @@ -3693,7 +3693,7 @@ cmdPoolStart(vshControl *ctl, const vshCmd *cmd) if (!vshConnectionUsability(ctl, ctl->conn, TRUE)) return FALSE; - if (!(pool = vshCommandOptPoolBy(ctl, cmd, "name", NULL, VSH_BYNAME))) + if (!(pool = vshCommandOptPoolBy(ctl, cmd, "pool", NULL, VSH_BYNAME))) return FALSE; if (virStoragePoolCreate(pool, 0) == 0) { diff --git a/tests/Makefile.am b/tests/Makefile.am index fd319e1..9e794c5 100644 --- a/tests/Makefile.am +++ b/tests/Makefile.am @@ -64,6 +64,7 @@ test_scripts += \ int-overflow \ read-bufsiz \ read-non-seekable \ + start \ undefine \ vcpupin virsh-all diff --git a/tests/start b/tests/start new file mode 100755 index 0000000..a436f9b --- /dev/null +++ b/tests/start @@ -0,0 +1,42 @@ +#!/bin/sh +# ensure that virsh start works properly + +# Copyright (C) 2008 Free Software Foundation, Inc. + +# This program is free software: you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation, either version 3 of the License, or +# (at your option) any later version. + +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Hello, i have the following piece of pyhton test code: try: dom = conn.createXML(xmldata, 0) except libvirt.libvirtError, le: sys.stderr.write(le.message) as a result in case of exception i get 2 outputs in stderr: libvir: OpenVZ error : operation failed: Already an OPENVZ VM defined with the id '3005' operation failed: Already an OPENVZ VM defined with the id '3005' Actually, i just need only second string, which is generated by sys.stderr.write(le.message). Can an exception be raised without "uncontrolled" direction to stderr (fisrt string)? ________________________________ This message (including attachments) is private and confidential.
