[Openstack] Creating a virtual machine using virsh commands

Hallo Haitao,

I am aware that creating VMs using virsh will not be recognized by Nova.

I am working with Ubuntu 12.04. I did the dumpxml of an existing VM and used the same xml for creating a new guest. But it throwed me an error. In the XML file, I am interested to know which key value pairs are to be used and which are to be deleted?

You do realize that creating VM using virsh will not be recognized by the Nova, right?

Which OS you are working with? If you use Ubuntu, you can use vm-builder. If you use CentOS, you can use virt-install. I had success stories with both.

If you have Nova running with some VMs, you can get an example of XML by doing
virsh list to list all VMs and then virsh dumpxml <vm>.

Hallo all,

I am trying to create a virtual machine using a XML file using libvirt. But I am getting an error during this creation process.

I am using the virsh commands in order to perform this action. Can somebody pass me an example XML file and also describe the steps for connecting to the VM?
