[libvirt] Release of libvirt-0.6.4
by Daniel Veillard 06 Jun '09

06 Jun '09

The monthly release is out ! There is a number of new things in that release, but as happens in time-based releases some are not fully complete, for example the OpenNebula driver was added but it still need a bit of work on the detection code and a bit of cleanup to avoid a GPL/AFS licencing issue, so please don't enable it except for test builds. We also have a new set of Interface config APIs but they are not yet implemented by a driver and the XML import/export routines are not there yet. Still there is a lot of things to use and discover in this release as you can see below: * New features: - new API virStorageVolCreateXMLFrom (Cole Robinson) - full VBox graphic capabilities (Pritesh Kothari) - Interface config APIs (Laine Stump) - APIs for domain XML conversions (Daniel Berrange) - initial version of OpenNebula driver (Abel Miguez Rodriguez) * Portability: - better compiler warning selection (Daniel Berrange) - Win32 portability fixes (Daniel Berrange) * Documentation: - documentation for <sound> device XML format (Cole Robinson) - storage format documentation fixes (Ryota Ozaki) - docs for XML conversion APIs (Daniel Berrange) - inconsistencies in storage volume docs and schemas (Ryota Ozaki) * Bug fixes: - fix hostdev managed handling (Mark McLoughlin) - lxc_controller should not cash without args (Guido Gunther) - bug fixes in I/O routines (Guido Gunther) - fix migrationsave/restore for QEmu 0.10.0 (Daniel Berrange) - avoid crash on VBox init (Guido Gunther) - fix dev and cgroup init in LXC (Ryota Ozaki) - QEmu startup fix (Cole Robinson) - block node reboots from LXCs (Ryota Ozaki) - QEmu argv detection fix for recent kvm (Daniel Berrange) - fix watch/timer event deletion (Daniel Berrange) - fix XML escaping bug - various locking bugs (Daniel Berrange) - avoid a deadlock in HAL nodedev driver (Cole Robinson) - detection of node device media insert/eject (Cole Robinson) - broken networking with new QEMU/KVM >= 86 (Daniel Berrange) - various fixes in domain and network startup error report (Cole Robinson) - double free on unexpected client disconnect (Daniel Berrange) * Improvements: - cleanups and doc on virExec (Cole Robinson) - error reporting in QEmu migrations (Cole Robinson) - better path and driver detection in VBox (Pritesh Kothari) - avoid caching QEMU driver capabilities(Cole Robinson) - multiple graphics elements definitions (Pritesh Kothari) - LSB init header init.d improvements (Frederik Himpe) - special erro code for invalid operations (Daniel Berrange) - dlopen error logging (Daniel Berrange) - fix UUID and name uniqueness (Daniel Berrange) - improvement on VBox initialization (Pritesh Kothari and Dan Berrange) - "Host only" and "Internal" network in VBox (Pritesh Kothari) - add utility virExecDaemonize (Cole Robinson) - enable bridges without IP (Ludwig Nussel) - 'make -s' silencing (Daniel Berrange) - test case for exercising the event loop (Daniel Berrange) - virsh commands vol-clone and vol-create-from (Cole Robinson) - new xend don't use [] around cpumaps (Tatsuro Enokura) - add the CIL mutex lock checker (Daniel Berrange) - fix some LXC error code (Amy Griffis) - virInterface python bindings (Daniel Berrange) - fix to the example code for event handling (Pritesh Kothari) - always add location informations to logging (Daniel Berrange) - python domain events example and binding (Daniel Berrange) - PPC Qemu Machine Type update (Thomas Baker) * Cleanups: - strings bug in virsh (Daniel Berrange) - various cleanups in storage code (Cole Robinson) - rpm spec cleanups - destructors data cleanups (Laine Stump) - some QEmu code refactoring (Daniel Berrange) - avoid dependancy on libcap (Daniel Berrange) - python import cleanup (Cole Robinson) - virAsprintf based cleanups in storage code (Cole Robinson) - fix some direct stderr logging - OpenNebula driver cleanups (Daniel Berrange) Thanks everybody for the contributions for this new release !

[libvirt] Regression in createQemuImg()@storage_backend_fs.c of 0.6.4
by Ryota Ozaki 05 Jun '09

05 Jun '09

Hi, I've found a regression in using a backing store of a volume (qcow2) in a pool (dir). The following code of 0.6.4 hits my system that works with 0.6.3. static int createQemuImg(virConnectPtr conn, virStorageVolDefPtr vol, virStorageVolDefPtr inputvol) { (snip) const char *inputBackingPath = (inputvol ? inputvol->backingStore.path : NULL); (snip) /* XXX: Not strictly required: qemu-img has an option a different * backing store, not really sure what use it serves though, and it * may cause issues with lvm. Untested essentially. */ if (!inputBackingPath || !STREQ(inputBackingPath, vol->backingStore.path)) { virStorageReportError(conn, VIR_ERR_INTERNAL_ERROR, "%s", _("a different backing store can not " "be specified.")); return -1; } The inputBackingPath will be always NULL when it is called via virStorageBackendFileSystemVolBuild(). (The third argument is passed to that of createQemuImg as it is.) static int virStorageBackendFileSystemVolBuild(virConnectPtr conn, virStorageVolDefPtr vol) { return _virStorageBackendFileSystemVolBuild(conn, vol, NULL); } I've addressed the regression with the patch - if (!inputBackingPath || + if (inputBackingPath && However, I'm not sure whether this fix satisfies the aim of the original code. Any idea? Thanks in advance, ozaki-r

[libvirt] IPv6 subnet on virbr0
by Bernie Innocenti 05 Jun '09

05 Jun '09

Hello, in a common scenario where there aren't enough public IPv4 addresses for all domains, I have elaborated this workaround: - the host operates a sixxs.net IPv6 tunnel with aiccu. - the virbr0 interface is manually configured an IPv6 address within a /64 subnet delegated by sixxs.net. (I do this from /etc/rc.local for lack of a better place) - radvd runs on the host to autoconfigure IPv6 for the guests on virbr0 and advertise the host as a gateway With this setup, all machines are globally addressable from the IPv6 internet, which is still quite useful for backstage services such as a build farm. In order to automate this setup, libvirt should support configuring an IPv6 address on bridged interfaces, and possibly multiple addresses for dual stack setups. Automatically running radvd would make a nice goodie. -- // Bernie Innocenti - http://codewiz.org/ \X/ Sugar Labs - http://sugarlabs.org/

[libvirt] virsh edit error
by Doug Goldstein 05 Jun '09

05 Jun '09

In an attempt to rename a kvm vm (which was powered off) I performed the following: $ virsh edit old-name Then changed <name>old-name</name> to <name>new-name</name> and saved and quit from the editor. $ virsh list --all Id Name State ---------------------------------- - old-name shut off - new-name shut off Performing an edit on each of these shows they're completely identical. Even the <name> section shows the old-name on both of them. I've performed restarts of libvirtd as well. If the action I did is truly invalid, we should catch that an error out on it. However I think VM renaming can be a valid use case and we have the UUID to match off of for the rename. Basically, I'm contacting the list to see if my use case was invalid and I should write my patch to spit an error, or if I should write my patch to correct the improper handling. Patch to follow based on responses. Thanks all. -- Doug Goldstein

[libvirt] [PATCH] fix a realloc problem
by Daniel Veillard 04 Jun '09

04 Jun '09

The xen code for detaching devices had a mistake in the resize compaction code, the size of the data copied was improper, moving N bytes, instead of sizeof(device) * N bytes. The attached patch by Dan Berrange fixes it, it's trivial so I commited it, 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/

[libvirt] PATCH: Fix redetection of transient QEMU VMs on daemon restarts
by Daniel P. Berrange 04 Jun '09

04 Jun '09

When the libvirtd daemon starts up, it reads all config files from /etc/libvirt/qemu. For each config file loaded, it then probes for a pidfile / live status XML config in /var/run/libvirt/qemu. In retrospect there is an obvious problem with this approach: it misses all transient VMs which don't ever have config files in /etc/libvirt/qemu. The core goal of this patch, is thus to change the way we deal with startup to apply the following logic. - Scan & load all status files in /var/run/libvirt/qemu for running VMs - Reconnect to the monitor for all VMs, and re-detect VCPU threads. - Scan & load all inactive configs in /etc/libvirt/qemu This ensures we always re-detect all inactive and running VMs, whether transient or persistent. It also fixes two other bugs, first we forgot to detect VCPU threads, so vCPU affinity functions were broken, and it also re-reserves the MCS category with selinux so it is not re-used later. Finally, if the attempt to reconnect to the QEMU monitor for a running VM fails, then we explicitly kill off that VM, rather than just ignoring it. This avoids leaving orphaned QEMU processes. The patch is larger than anticipated, because I moved all the status file code out of QEMU driver into the generic domain_conf.c file. This enables both scanning loops to be done via the single method virDomainLoadAllConfigs, just by pasing different directories. I also want to re-use this code in the LXC and UML drivers to improve bugs in their logic domain_conf.c | 314 ++++++++++++++++++++++++++++++++++++++++++++++----- domain_conf.h | 17 ++ libvirt_private.syms | 1 lxc_driver.c | 2 qemu_conf.c | 190 ------------------------------ qemu_conf.h | 18 -- qemu_driver.c | 178 +++++++++++++--------------- security.h | 3 security_selinux.c | 39 ++++++ uml_driver.c | 4 10 files changed, 431 insertions(+), 335 deletions(-) Daniel diff --git a/src/domain_conf.c b/src/domain_conf.c --- a/src/domain_conf.c +++ b/src/domain_conf.c @@ -39,6 +39,7 @@ #include "util.h" #include "buf.h" #include "c-ctype.h" +#include "logging.h" #define VIR_FROM_THIS VIR_FROM_DOMAIN @@ -511,6 +512,31 @@ void virDomainObjListFree(virDomainObjLi vms->count = 0;

HI I have downloaded and tried with both libvirt-0-6-2 %libvirt-0-6-4 versions to build the One Driver from the source directory I executed the following commands to install libvirt >./autogen.sh -with-one=yes ------------>success >make -----------------------> also succeeded >make install -----------------------> also succeeded >virsh -c one:/// execution is giving me the following error hexagrid@hexagrid-desktop:~$ virsh -c one:/// error: failed to connect to the hypervisor hexagrid@hexagrid-desktop:~$ let me know whether I have performed the right steps to install or anything is missing. but I am able to connect to QEMU driver and the out of the execution is as follows hexagrid@hexagrid-desktop:~$ virsh -c qemu:///session Welcome to virsh, the virtualization interactive terminal. Type: 'help' for help with commands 'quit' to quit -- Thanks and Regards Thirupalu Annam ---------------------------------------- Hexagrid Networks Office :23350089, 40144654 Mob:9908377725

[libvirt] Libtool problem
by Eduardo Otubo 04 Jun '09

04 Jun '09

Hello all, I found this when compiling the last git commit (0a29f59e3b8e2c1fb797d2fa93831f21a3e1711e). This is the first compilation from my new Ubuntu instalation (9.04) so I cannot figure out if it is a libvirt problem or if it is any configuration problem. I configured the compilation with './configure --with-phyp=yes --with-xen=no' and the make exit is the following: otubo@lisa ~/develop/libvirt/src $ make make all-recursive make[1]: Entering directory `/home/otubo/develop/libvirt/src' Making all in gnulib/lib make[2]: Entering directory `/home/otubo/develop/libvirt/src/gnulib/lib' make all-recursive make[3]: Entering directory `/home/otubo/develop/libvirt/src/gnulib/lib' make[4]: Entering directory `/home/otubo/develop/libvirt/src/gnulib/lib' /bin/bash ../../mylibtool --tag=CC --mode=compile gcc -DHAVE_CONFIG_H -I. -I../.. -I../../intl -g -O2 -MT c-ctype.lo -MD -MP -MF .deps/c-ctype.Tpo -c -o c-ctype.lo c-ctype.c (CC) -o c-ctype.lo c-ctype.c /home/otubo/develop/libvirt/src/gnulib/lib/../../libtool: line 847: X--tag=CC: command not found /home/otubo/develop/libvirt/src/gnulib/lib/../../libtool: line 880: libtool: ignoring unknown tag : command not found /home/otubo/develop/libvirt/src/gnulib/lib/../../libtool: line 847: X--mode=compile: command not found /home/otubo/develop/libvirt/src/gnulib/lib/../../libtool: line 1014: *** Warning: inferring the mode of operation is deprecated.: command not found /home/otubo/develop/libvirt/src/gnulib/lib/../../libtool: line 1015: *** Future versions of Libtool will require --mode=MODE be specified.: command not found /home/otubo/develop/libvirt/src/gnulib/lib/../../libtool: line 1158: Xgcc: command not found /home/otubo/develop/libvirt/src/gnulib/lib/../../libtool: line 1158: X-DHAVE_CONFIG_H: command not found /home/otubo/develop/libvirt/src/gnulib/lib/../../libtool: line 1158: X-I.: command not found /home/otubo/develop/libvirt/src/gnulib/lib/../../libtool: line 1158: X-I../..: No such file or directory /home/otubo/develop/libvirt/src/gnulib/lib/../../libtool: line 1158: X-I../../intl: No such file or directory /home/otubo/develop/libvirt/src/gnulib/lib/../../libtool: line 1158: X-g: command not found /home/otubo/develop/libvirt/src/gnulib/lib/../../libtool: line 1158: X-O2: command not found /home/otubo/develop/libvirt/src/gnulib/lib/../../libtool: line 1158: X-MT: command not found /home/otubo/develop/libvirt/src/gnulib/lib/../../libtool: line 1158: Xc-ctype.lo: command not found /home/otubo/develop/libvirt/src/gnulib/lib/../../libtool: line 1158: X-MD: command not found /home/otubo/develop/libvirt/src/gnulib/lib/../../libtool: line 1158: X-MP: command not found /home/otubo/develop/libvirt/src/gnulib/lib/../../libtool: line 1158: X-MF: command not found /home/otubo/develop/libvirt/src/gnulib/lib/../../libtool: line 1158: X.deps/c-ctype.Tpo: No such file or directory /home/otubo/develop/libvirt/src/gnulib/lib/../../libtool: line 1158: X-c: command not found /home/otubo/develop/libvirt/src/gnulib/lib/../../libtool: line 1211: Xc-ctype.lo: command not found /home/otubo/develop/libvirt/src/gnulib/lib/../../libtool: line 1216: libtool: compile: cannot determine name of library object from `': command not found make[4]: *** [c-ctype.lo] Error 1 make[4]: Leaving directory `/home/otubo/develop/libvirt/src/gnulib/lib' make[3]: *** [all-recursive] Error 1 make[3]: Leaving directory `/home/otubo/develop/libvirt/src/gnulib/lib' make[2]: *** [all] Error 2 make[2]: Leaving directory `/home/otubo/develop/libvirt/src/gnulib/lib' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/otubo/develop/libvirt/src' make: *** [all] Error 2 It seems there is a strange error form libtool, it's not recognizing some options, or some malformed options there is being passed to libtool.

[libvirt] Problem compiling libvirt-0.6.3
by Rohit Bhoj 03 Jun '09

03 Jun '09

Hello, I am facing problems getting the libvirt dependancies resolved. I am trying to compile libvirt-0.6.3 on a 64-bit SLES 11 machine. I have manually tried to resolve many dependancies, but am stuck at the GnuTLS library dependancy. The machine contains gnutls-2.4.1-24.15 installed, but still the configure script of libvirt gives an error saying : 'checking for gnutls_handshake in -lgnutls... no configure: error: You must install the GnuTLS library in order to compile and run libvirt' Can you please help me resolve this dependancy. Is there any place where I can get all the dependancy rpms needed for libvirt? Regards, Rohit Bhoj Bollywood news, movie reviews, film trailers and more! Go to http://in.movies.yahoo.com/
