Hi, I am trying to attach a usb device to my virtualbox node using libvirt. My node is already running, I stop my node and then I am trying to add this usb device. I have a separate xml file defined for usb. It looks like this: *<device> <hostdev mode='subsystem' type='usb'> <source> <vendor id='0x4321'/> <product

These are the messages that I get when trying to attach a virtio disk to or perform a shutdown of the problem vm guest. Add hardware This device could not be attached to the running machine. Would you like to make the device available after the next guest shutdown? Requested operation is not valid: cannot do live update a device on inactive domain Traceback (most recent call last): File

Hi all, I am trying to install a version of Libvirt that will be compatible with qemu-kvm-1.1 but I cannot seem to get Libvirt to compile.

Hi all, I've disabled cgroups v1 on my system with the kernel boot option "systemd.unified_cgroup_hierarchy=1". Since doing so, USB hotplugging fails to work, seemingly due to a permissions problem with BPF. Please note that the technique I'm going to describe worked just fine for hotplugging USB devices to running domains until this change. Attaching / detaching USB devices

Hi, I''m a long ext3 user (rpmfind.net). I propagated ext3 on some of our server box (W3C webservers are ext3 based too now). I might be tempted of testing out your kernel RPMs but unavailability or the source RPM and the SMP version are definite showstoppers. Please provide them. In the meantime I will stick to my own set of kernel ext3 RPMs at ftp://rpmfind.net/pub/veillard/ext3/

Hi, Is there any way you can save a xen domain without suspending it or stopping it? I want to set up something so if my xen session crashes I can fire up another xen session from the save file that I created 5 minutes before the crash and hopefully minimize downtime.

I've not seen this asked since I've been on the list; but was wondering... I'm currently sticking to the 2.2 line and have no plans to move to 2.4 right now. Is there any attempt to back port some of the changes in the newer 2.4 line back into 2.2? ext-0.0.7a.tar.gz has been stable thus far, but it's getting kind of old. NEM

Hi all, I'm using libvirt java binding (libvirt-java-0.4.6) I'd like to know if the Domain class offers an API to query volumes attached to a particular domain or should I parse the XML domain description?

Has support for creating or using lxc containers on remote machines been added to libvirt yet? https://help.ubuntu.com/12.04/serverguide/lxc.html says "Libvirt is a powerful hypervisor management solution with which you can administer Qemu, Xen and LXC virtual machines, both locally and remote." so I assume it's been done and I'm just having trouble seeing it... otoh, I hear

Hi, IIR/UC there have been a couple of discussions lately about possible evolution of libvirt's network management features to eventually support more kinds of virtual networking technologies like Openvswitch, VDE,... Could a kind and informed soul keep us on touch with progress in the field ? Thank you very much in advance PS: I wish this will be available before/for 1.0 release...

Are there any recommendations as to how often a new connection should be made versus reused? Right now we create a new connection *every time* we hit libvirt for something. We can easily change this so that a single connection is made for a series of libvirt calls, or even so that a single connection is used for the lifetime of the running application. What are the issues to consider when making

Hi, I'm revisiting my libVirt install for opensolaris. I downloaded libvirt 0.8.0.. This is a bit embarassing, but I forgot how to build libVirt on opensolaris.
