Hi all, I talked to our oVirt developers who use CentOS for upstream development. And that's what makes their lives hard because it takes a long time before they can start using new features of libvirt. The latest released CentOS version is 7.2 with libvirt 1.2.17, which is pretty old. But even when CentOS 7.3 with libvirt 2.0.0 gets released, it will already be old since libvirt 2.5.0 is

hello , thanks for comments . I tried now with force options for CPU flag which were not supported . Now the command with non fully supported CPU model gets executed , But i am surprised to see that still Guest cpu model is not changed and still same as host cpu model(SAndy Bridge) Why don't i see the model as HAswell now , could you please comment. Command used : virt-install

The problem desribed here: https://bugzilla.redhat.com/show_bug.cgi?id=593266 Please update http://www.libvirt.org/formatdomain.html and describe NEW xml tags, like <serial>xxxx</serial> for hard drive and all cpu tags, other if any. -- Segmentation fault

Hi There, I am using Libvirt 1.2.1 on Fedora 20. So, Libvirt is well installed and started but the weird thing is that the 'default' virtual network is not automatically defined and started, knowing that I can define/start it manually and everything goes fine. previously I was using libvirt 1.0.4 and the 'default' virtual network was defined/started at Libvirt startup. so,

ok thanks , but then can we know which all list of feature are supported by QEMU/KVM release. http://www.linux-kvm.org/page/KVM_Features Does not seem to be all corect .

Hi all, I am trying to bring up lxc's using Libvirt JAVA API. I do the following: conn = Connect("lxc:\\\") xml_config = "<domain> .... <\domain>" dom = conn.domainCreateXML(xml_config, 0) dom.create() Using the above code, I am able to start a domain but the domain is not visible within the "lxc" list, i.e when I use the command "lxc-ls

Hello all, I find this curious behavior that libvirt will automatically insert a USB controller and a memballoon virtio driver into the domain's XML, when defineXML is called. IOW, the original XML did not have these 2 devices but they are present right after defineXML is called. Why should libvirt add a USB controller? DETAILS: Here is a little Python snippet to show that behavior:
