[libvirt-users] Release of libvirt-0.8.2
by Daniel Veillard 06 Jul '10

06 Jul '10

Following Dan advice, I decided to not wait for more patches and push the current git head as the release. Let's plan to have another release by this month end with the QEmu debugging and hacking APIs. The release is available as usual at ftp://libvirt.org/libvirt Quite a lot of bug fixes during the two months since 0.8.1, and a few new feature. It also tagged more commits as being documentation or portability fixes, it's good :-) Features: - phyp: adding support for IVM (Eduardo Otubo) - libvirt: introduce domainCreateWithFlags API (Eric Blake) - add 802.1Qbh and 802.1Qbg switches handling (Stefan Berger) - Support for VirtualBox version 3.2 (Jean-Baptiste Rouault) - Init script for handling guests on shutdown/boot (Jiri Denemark) - qemu: live migration with non-shared storage for kvm (Kenneth Nagin) Documentation: - html docs: add link to PHP bindings by Radek Hladik (Justin Clift) - virsh: document attach-disk better (Eric Blake) - bridge_driver.c: fix file description (Alan Pevec) - nwfilter: extensions of docs with (Stefan Berger) - Fix description of virStorageVolGetInfo() (Philipp Hahn) - virsh: improve help text for vol query commands (Justin Clift) - virsh: fixed trivial comment and debug message in vshCommandOptVolBy function (Justin Clift) - virsh: remove xen reference in header comment (Justin Clift) - virsh: add the volume commands to the virsh man page (Justin Clift) - virsh: fix minor virsh man page typos and formatting problems (Justin Clift) - Trivial virsh.pod additions --all for "list" command and similar (Justin Clift) - Add docs on drive <serial> element (Марк Коренберг) - daemon: sysconf: Update comment about VNC audio (Cole Robinson) - nwfilter: documentation (Stefan Berger) - docs: distribute more coding convention documentation (Eric Blake) - note a typo: VIR_MIGRATE_TUNNELLED should be VIR_MIGRATE_TUNNELED, (Jim Meyering) - datatypes: fix comment typo (Eric Blake) - Fix a typo in docs (Ersek Laszlo) - docs: hacking: explain why using curly braces well is important (Jim Meyering) Portability: - cgroup: Fix compilation broken on MinGW due to dirent->d_type (Ryota Ozaki) - parthelper: fix compilation without optimization (Eric Blake) - build: fix some mingw issues (Eric Blake) - build: avoid pthreads-win32 on mingw (Eric Blake) - build: fix cygwin build, correctly this time (Eric Blake) - build: fix up some compiler flags (Eric Blake) - build: avoid compile failure on linux kernels older than 2.6.19 (Jim Meyering) - libvirt_proxy: link with -lpthread if needed (Eric Blake) - build: allow older gettext (Eric Blake) - mingw32-libvirt.spec: bring up to date (Eric Blake) - avoid link error in tests using libvirt_util; due to pthread_sigmask (Jim Meyering) - configure.ac: Avoid uname, which breaks cross-compilation (Matthias Bolte) - mingw: Fix two undefined symbols (Matthias Bolte) - build: avoid compiler warning (Eric Blake) - build: prefer WIN32 over __MINGW32__ checks (Eric Blake) - dnsmasqReload: avoid mingw link failure (Eric Blake) - mingw: Fix symbol export (Matthias Bolte) Bug Fixes: - Avoid invoking the qemu monitor destroy callback if the constructor fails (Daniel P.

[libvirt-users] ESXi support
by adrian wyssen 03 Jul '10

03 Jul '10

Hello everyone, I want to use libvirt to manage an Vmware ESXi 4.0 server from within a virtual machine running on that server. I did not find any C examples using ESX(i). Can anyone give me some example code, because I am really new in this domain and I can't get started... I don't find any information about using libvirt with ESX(i), even if it is supposed to work with it. I thank you for any information. Adrian

[libvirt-users] ANNOUNCE: ruby-libvirt bindings 0.2.0
by Chris Lalancette 02 Jul '10

02 Jul '10

Hello all, I'm pleased to announce the release of 0.2.0 of the ruby-libvirt bindings. This release has a number of new features: - Updated Storage class, implementing pool.active?, pool.persistent?, pool.vol_create_xml_from - Updated Connect class, implementing conn.node_free_memory, conn.node_cells_free_memory, conn.node_get_security_model, conn.encrypted?, conn.libversion, and conn.secure? - Updated Network class, implementing network.active? and network.persistent? - Update Domain class, implementing conn.domain_xml_from_native, conn.domain_xml_to_native, dom.migrate_to_uri, dom.migrate_set_max_downtime, dom.managed_save, dom.has_managed_save?, dom.managed_save_remove, dom.security_label, dom.block_stats, dom.memory_stats, dom.blockinfo, dom.block_peek, dom.memory_peek, dom.active?, dom.persistent?, dom.snapshot_create_xml, dom.num_of_snapshots, dom.list_snapshots, dom.lookup_snapshot_by_name, dom.has_current_snapshot?, dom.revert_to_snapshot, dom.current_snapshot, snapshot.xml_desc, snapshot.delete, dom.job_info, and dom.abort_job - Implementation of the NodeDevice class - Implementation of the Secret class - Implementation of the NWFilter class - Implementation of the Interface class - Conversion of the development tree to git - New maintainer (me). David Lutterkort has agreed to transfer maintainership of the bindings over to me, since he is not actively involved in their development anymore. With the above list, almost all of the APIs up to and including libvirt 0.8.1 are covered. There are a few that I have not yet had time to implement; you can look at the list of FIXMEs in the source code to find them. I've uploaded new tarballs and source RPMs to: http://libvirt.org/ruby/download/ The new git repo is here: http://libvirt.org/git/?p=ruby-libvirt.git;a=summary The documentation for the new API's are here: http://libvirt.org/ruby/api/index.html If you have time, and are interested in the bindings, please give these new ones a whirl and let me know if they work for you. As usual, if you have any questions, problems, patches, or bug reports, feel free to email the libvirt development list (and CC me) so that I can take a look at them. -- Chris Lalancette

[libvirt-users] C API example
by steven765＠yahoo.com 02 Jul '10

02 Jul '10

Trying to build the hellolibvirt example. I get the project to compile okay but when I try to run it I get: Unable to connect to '/usr/local/var/run/libvirt/libivrt-sock Given libvirt --status says it's in /var/run/libvirt/libvirt-sock that makes sense. How do I make the git version run with my local copy? Or even better does anyone have any example projects that have the proper includes documented, seperate from the build tree? I'd like to just use the API not compile and deal with all of libvirt at the moment. Thanks a ton!

[libvirt-users] qemu+ssh auth with different identity files

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I'm trying to get qemu+ssh auth working but I need to be able to specify an identity file to use for the ssh connection.

[libvirt-users] Some missunderstanding in the wiki page
by Leopold Palomo-Avellaneda 01 Jul '10

01 Jul '10

Hi, I'm not in the list and I just would like to comment it to the comunity. So, if someone want to contact me, make CC to me in the reply. The wiki page [1] talk about networking, and show two typical configurations: "virtual network" and "shared physical device". The shared physical device has an error or something that could make confused, I think. What I want to say? In my case, I have a box with several nics, and I want to speciffy that ethX should be used exclusively but virtual domain X. The documentation is clear in this: The NAT based connectivity is useful for quick & easy deployments, or on machines with dynamic/sporadic networking connectivity. More advanced users will want to use full bridging, where the guest is connected directly to the LAN. The configuration (I have follow only the debian/ubuntu steps) shows that br0 has assigned an IP. I did the mistake to try to assign the same IP in the guest network configuration, I understand that, and obviously it doesn't work (duplicate IPs). So, to me, it would me more clear if the br0 interface has no IP. In my case, I have two nics: eth0 the interface for the host and eth1 for the guest. The eth1 part in my network/interfaces is: ... auto eth1 iface eth1 inet manual auto br0 iface br0 inet manual bridge_ports eth1 bridge_stp on bridge_maxwait 0 bridge_fd 0 ... and then in the guest you configure the IP as you want. In the host, eth1 (or whatever interface you bridge) has no IP, so it's not used, and the guest uses completely. What do you think? Regards, Leo [1] http://wiki.libvirt.org/page/Networking

My server and client are running Ubuntu Lucid, libvirt-bin 0.7.5-5ubuntu27, qemu-kvm-0.12.3+noroms-0ubuntu9 and I'm using virt-viewer-0.0.3-6ubuntu7.xul19 or virt-manager-0.8.2-2ubuntu8 to connect. I configured SASL2 to use GSSAPI for libvirt following the instructions in the libvirt docs, created a keytab with libvirt/my.fully.qualified.domain(a)MY-REALM.COM (has a dash fwiw) and pointed SASL2 and libvirt at /etc/krb5.keytab (changing the location of that doesn't seem to work for my version, but that's no biggie). So I sit on my client and run this: virsh -c qemu+tcp://my.fully.qualified.domain/system And I get this message on the client: error: authentication failed error: failed to connect to the hypervisor And this on the server logs: 16:37:35.278: error : remoteDispatchAuthSaslStart:3135 : sasl start failed -1 (SASL(-1): generic failure: GSSAPI Error: Unspecified GSS failure. Minor code may provide more information (Key table entry not found)) For fun, I ran kdestroy and tried again and got this: error: Failed to start SASL negotiation: -1 (SASL(-1): generic failure: GSSAPI Error: Unspecified GSS failure. Minor code may provide more information (Credentials cache file '/tmp/krb5cc_1000' not found)) error: failed to connect to the hypervisor So at least the client seems to be presenting my ticket properly, but the server is either looking for the wrong keytab entry or I can't read very well. -adam

[libvirt-users] non-root user "virConnectOpen() faile" in libvirt-0.3

*Hello,* * * *My environment is "Xen3.1 in Fedora8" with "libvirt0.3 & python2.5". When I ran the following * *commands as a non-root user "nimbus":* $python >>> import libvirt >>> libvirt.open("xen:///") --------- Console --------- [nimbus@localhost-120 ~]$ python Python 2.5.1 (r251:54863, Oct 30 2007, 13:54:11) [GCC 4.1.2 20070925 (Red Hat 4.1.2-33)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import libvirt >>> libvirt.open("xen:///") Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python2.5/site-packages/libvirt.py", line 123, in open if ret is None:raise libvirtError('virConnectOpen() failed') libvirt.libvirtError: virConnectOpen() failed >>> *I encountered the error "virConnectOpen() failed". if I changed the user into root, it worked well. * *But I hava to use the non-root account "nimbus". I looked into the problem on the net, in order * *that non-root user could use libvirt as root user, someone suggested that I should modify the libvirt * *configuration file "/etc/libvirt/libvirtd.conf", but they didn't point out what field should be changed.* * * *I am puzzled about that problem. I have already changed the sudo file and the xen configuration * *file "/etc/xen/xend-config.sxp", which doesn't work at all. Could someome give me any tips? * --------- "/etc/xen/xend-config.sxp" --------- (xend-http-server yes) (xend-unix-server yes) (network-script network-bridge) * * *Thanks in advance!* * * *Cheers,* * * *Shenglan Wang*
