similar to: migrate a guest from VMware to KVM

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')

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

Hi all, I am trying to figure out if you can store the definition of a directory storage pool in a custom location. This is how I create the storage pool: xmlDesc = """ <pool type='dir'> <name>guest_images_storage_pool</name> <uuid>8c79f996-cb2a-d24d-9822-ac7547ab2d01</uuid> <capacity unit='bytes'>4306780815</capacity>

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>

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 trying to add libvirt to a linux machine running a custom built linux- there is no packet manager, everything is compiled using buildroot. On this VM server, I am running libvirt-1.2.2 and the linux kernel is 3.18.21 Libvirtd starts and runs in the background. I can add/edit VMs using Virt-install. If I try to connect to the local qemu, everything works: virsh -c qemu:///system If I ssh in

Hi all, I think I might have a small configuration issue: after restarting my machine, all the VMs previously installed are not available. virsh list --all shows an empty list. The .img files where the VMs were intalled are present in the folder I put them in. Furthermore if I import the VMs (virt-install -import) it all seems to work. It's just that I don't want to have to do this
