Hi all, I am using libvirt to manage VM on my system; after creating a VM (default no NICs are present in the configuration) you can add any number of interfaces to it (as long as they exist on the host). To do that, I edit the configuration xlm: vmXml = self.domain.XMLDesc() root = ET.fromstring(vmXml) devices = root.find('./devices') intf =

I am trying to change a domain configuration from a python script. More specific, I want to edit the VNC settings. You can't do this using the libvirt API so you have to edit the domain configuration: Fo exmple, to disable VNC for a domain 'test1': vmXml = vm.XMLDesc(0) root = ET.fromstring(vmXml) devices = root.find('./devices') graphics = devices.find('graphics')

I am trying to migrate a VMware guest to KVM. I have the .vmdk file which I convert to qcow2 format using qemu-img convert. The next step is to import the new img file. If I use virt-install --import <guest config options> it all works fine. But when I try the same think using the libvirt API I get the "no boot disk found" message when starting the vm. When importing the VM

I'm trying to clone a volume in a storage pool and I'm following the steps described here: http://libvirt.org/docs/libvirt-appdev-guide-python/en-US/html/libvirt_application_development_guide_using_python-Storage_Pools-Cloning.html My code looks like: destXML = """ <volume>

Hi all, I have the following issue, and I hope someone know a way to handle it. I need to grammatically need to create/install a guest OS using the libvirt API. Currently what I do: 1. create a xml with the vm configuration (this will include a path to the iso image) 2. connection.defineXML(<my_config>) 3. vm = connection.lookupByName(<domain_name>) 4. vm.create() This will

I am building a custom Linux image which includes KVM and will be installed on multiple machines. By default when installing libvirt you get a 'default network' which adds a 'vrbr0'. I found several tutorials online about removing this 'virbr0' but I would like to not have it in the first place. I am compiling libvirt from source so I would think there is some compile time

I am using the libvirt API to manage VMs on the system, using a python wrapper to execute commands. I need to allow a webserver to access these commands and mostly read information about the VMs. The problem is that when using the web interface you use are basically running the commands as different user. Since libvirtd is run as root by default you get permission errors. Is there any way of

Hi all, I am running KVM on a 3.18 kernel. The system runs and Atom processor with 2Gb RAM. Using KVM you obviously can over allocate your resources: say you have 4 guests each configured with 1GB ram. Running all four at the same time, depending on the workload, can crash the system - I get a kernel trace when this happens. But let's consider a simpler case: one guest with 1.5 Gb RAM,

Hi Andrea, Thanks for the reply; To shed some more light on the matter I performed a few more tests; each time doing a clean install. I installed ubuntu14.04 as the guest OS, keeping everything else the same. On my custom Linux I've created ubuntu VMs before (using ide drivers) and it all works file. This time I created the VM using virtio disk drivers and the installation didn't

I just ran into a problem I can't make heads or tails of, so I'm hoping to get some help here. I have a custom built Embedded Linux running qemu-kvm 1.1.2 and libvirt 1.2.20 I'm creating a domain with the following config: <domain type='kvm'> <name>myVM</name> <memory unit='KiB'>2097152</memory> <vcpu

Tanks for the reply Eric. The only reason I'm not going through the API is because there is nothing in the API (AFIK), that will allow you to modify the VNC settings, i.e. enable/disable, change port number. So I figured, the only way to do it is to modify the XML. I can't use virsh edit because I need this whole behavior scripted. So now if I want to change the VNC settings it

I am using libvirt 1.2.20. I noticed that when running some VMs (CentOS ) with 2G ram, 2CPUs each for some reason they go from 'state=running' to 'state=paused'; and they can't be restarted. They are un-usable. When this happens I get the following in dmesg output: [ 46.595265] EPT: Misconfiguration. [ 46.595271] EPT: GPA: 0xfee000b0 [ 46.595275]

I have the following running on my system: - one linux host running libvirt 1.2.20 - two Linux guestOS VMs running When I change the clock on the host, the VMs stop responding: The VNC connection stops working, the console connection to the VMs does not work, ping stops reponding, libvirt commands temporarily stop working (after issuing the command, the system just hangs). I get control
