On libvirt 0.10, the maximum seems to be 77 characters. Domains with names of 78 characters or more fail to start with the following errors:

> When VCL use KVM and libvirt provisioning module to create an new image, it does not check the length of the image name. However, libvirt restrict the length of the name for a VM to be less than 50 characters. When I create an new image, VCL can create a very long image name, and final VM's name can be longer than 50 characters and libvirt will reject to boot the VM.
