Hi all, A simple question, I hope ;) Is it possible to enable the qemu monitor in libvirt's xml? It need the monitor, to dynamically add a usb device to a windows vm. Regards, Eric

[libvirt] gnome-applet-vm orphaned
by Karel Zak 12 Aug '08

12 Aug '08

Hi folks, unfortunately, I have not enough time to work on the gnome applet. I'm looking for a new upstream maintainer, or for co-maintainer. Project home page: http://fedorahosted.org/gnome-applet-vm/ Note that the applet does not require any heavy development. Any volunteers around? Karel -- Karel Zak <kzak(a)redhat.com>

[libvirt] [PATCH] Ensure parted doesn't prompt if labeling disk
by Cole Robinson 12 Aug '08

12 Aug '08

Trying to 'build' a disk pool uses 'parted mklabel' which can prompt for confirmation. Patch adds the '--script' option to remove the chance of this happening. Thanks, Cole

[libvirt] Announcement of a companion project the "UnifiedSessionsManager"
by acue 12 Aug '08

12 Aug '08

Hello, I would like to announce the unifiedSessionsManager(GPL3, including the claimed inventions), which is based for Xen on the virsh-tool, but basically uses a different approach. I guess it could be a quite usable companion of libvirt for advanced usage and enhanced customizabelity of the handling of huge amounts of virtual and physical machines in a distributed environment. It is targeting on test, development and productive environments. This requirement will particularly arise, when "bulk-core-CPUs" enter the market, providing for independently executed bulks of virtual machines, which may be logically designed as stacked and nested VMs, founding a tree like multi-layered structure of VM clusters. The design-preview as estimated by the unifiedSessionsManager is here the v-component, what could be seen as the extensin of the slogan/concept of a so called virtual appliance, where a full scale VM including it's inherent GuestOS is handeled as a virtual software component. V-Compoents are foreseen to be grouped into clusters of VMs, arranged within a nested VMSTACK and managed - e.g. suspended - as a group of services, founding a combined service by their self. In case this preview becomes reality, this may have an impact on the basic design, particularly the interface design of each of it's components to be stack-aware, thus for libvirt too. For example providing the shutdown of a stack of VMs, including the suspension of machines containing upper VMs, might require some kind of communications and propagation.. The usage of multilayered VMSTACKs is already supported by the unifiedSessionsManager. Particularly MACRO and GROUP features support for handling of the number of entities required to be handled for a VMSTACK. Whereas much of the required functionality from the VMs is simulated, particularly by utilizing a recursive Stack-Propagation based on native access to GuestOSs with SSO-accounts. The concrete supported products of current version 01_07_001b02 are: - GuestOS and HostOS on physical machines: CentOS, Fedora, debian, OpenSUSE, Ubuntu, OpenBSD, Solaris10(limited) - Hypervisors/Emulators: QEMU, Xn, VMware(workstation,server,player) Future Plans are, mostly for the next version already: -Planned-OS: FreeBSD, NetBSD, Solaris10(complete), OpenSolaris, ScientificLinux -Planned-OS: eCos(?), uCLinux(several ARCH), SkyEye, ... -Planned-VM: VirtualBOX(evaluation first), OpenVZ(evaluation first) .Introduction of a LDAP based nameservice for VMs. -Evaluation of:Cygwin The Idea was the easy to adapt utilization of a minimalistic-bash-scripts only implementation for setting up a unified wrapper interface customizable for almost any kind of user sessions by almost anyone. Even though I would prefer now at least Perl or for specific parts full scale C/C++ code and Java/JavaScript for some administrative parts. The managed user environment comprises sessions to VMs which could be allocated in a nested multilayered VMSTACK as well as within a PM, which are physical machines - layer-0 entities. Also HOSTs sessions as native access to GuestOSs are integrated. Additionally a simple implemented but with sophisticated functionally equipped cache database is introduced in order to support for hundreds and thousands of virtual machines to be managed, with an average query-response-time for single-level-filters of less than 1second. Results are measured with an average of 0.3-0.8seconds in the ref.-env., even though bash and awk is mainly used only with an Office-Compatible record format. Information could be found within the User-Manual, which has more than 600pages, and within the sources of more than 110.000LinesOfCode. The following sites provide downloads: http://www.heise.de/software/download/unified_sessions_manager_ctys/51630 http://www.unifiedsessionsmanager.org http://www.unifiedsessionsmanager.eu http://sourceforge.net/projects/ctys (sourceforge not yet complete) (berlios follows) There are basically three reasons for sending this Mail: 1. Announcing a new supplemental project focusing on usage of distributed and stacked VMs 2. Getting some feedback and ideas for the future direction of the development of libvirt and the unifiedSessionsManager. 3. Probably initiation of setting up a common overall concept for the future vision of an IT environment and it's integrated handling of VMs. And of course, I would appreciate, if the current version already is of some benefit for the OpenSource community.

[libvirt] [PATCH/RFC]: hostdev passthrough support
by Guido Günther 12 Aug '08

12 Aug '08

Hi, attached is some basic support for host device passthrough. It enables you to passthrough usb devices in qemu/kvm via: <devices> <hostdev type='usb' vendor='0204' product='6025'/> <hostdev type='usb' bus='001' device='007'/> </devices> I didn't implement unplug yet since this needs some modifications to qemu/kvm to be able to identify the correct device to unplug. Does this look reasonable? -- Guido

[libvirt] [PATCH] fix MinGW compilation(200808)
by Atsushi SAKAI 12 Aug '08

12 Aug '08

Hi, Currently, compilation for MinGW is broken. Here is the patch. But configure script option for MinGW is changed from previous posting. https://www.redhat.com/archives/libvir-list/2008-June/msg00145.html Currently, it should do # ./configure --without-xen --without-qemu --without-sasl --without-lxc --without-openvz --without-libvirtd --without-test currently following 3 make works, make make install make check I do not know why syntax-check is not exist on Makefile on MinGW. src/domain_conf.c | 2 ++ src/network_conf.c | 2 ++ src/virsh.c | 8 ++++++++ tests/testutilsxen.c | 2 ++ 4 files changed, 14 insertions(+) Thanks Atsushi SAKAI

[libvirt] /var/run/libvirt
by Stefan de Konink 11 Aug '08

11 Aug '08

It is a trivial error, but i wonder if: Failed to change group ownership of /var/run/libvirt Failed to bind socket to '/var/run/libvirt/libvirt-sock': No such file or directory This could be corrected to: /var/run/libvirt doesn't exist or an mkdir is done on the directory... Stefan

[libvirt] virStoragePoolRefresh (costs)
by Stefan de Konink 10 Aug '08

10 Aug '08

Could anyone elaborate on the cost of running virStoragePoolRefresh on the different backends. I recall one of the Daniels here suggested it was expensive for some backends could anyone elaborate on it? Stefan

[libvirt] [ANNOUNCE] virt-mem tools version 0.2.8 released
by Richard W.M. Jones 10 Aug '08

10 Aug '08

I'm pleased to announce the latest release of the virt-mem tools, version 0.2.8. These are tools for system administrators which let you find things like kernel messages, process lists and network information of your guests. For example: virt-uname 'uname' command, shows OS version, architecture, etc. virt-dmesg 'dmesg' command, shows kernel messages virt-ps 'ps' command, shows process list Nothing needs to be installed in the guest for this to work, and the tools are specifically designed to allow easy scripting and integration with databases and monitoring systems. Source is available from the web page here: http://et.redhat.com/~rjones/virt-mem/ The latest version (0.2.8) reworks the internals substantially so that we have direct access to basically any kernel structure, and this will allow us to quickly add the remaining features that people have asked for (memory usage information, lists of network interfaces and so on). As usual, patches, feedback, suggestions etc. are very welcome! Binaries will be available in Fedora 10 (Rawhide) at some point soon. Rich. -- Richard Jones, Emerging Technologies, Red Hat http://et.redhat.com/~rjones virt-top is 'top' for virtual machines. Tiny program with many powerful monitoring features, net stats, disk stats, logging, etc. http://et.redhat.com/~rjones/virt-top
