Personally I've never used the 9p kvm share method to access server resources in a VM, as I find it slower and more difficult to manage than accessing the shares using SMB, just like you would with a physical machine elsewhere on the network. All the SMB traffic stays internal to the box, so it's much faster than a physical machine on the LAN. 9p may be better performing now, but I'd never know it since SMB still works well for me.
As for copying the XML, I've found that generating a fresh XML and making the needed changes like pointing to a specific vdisk works much better.

I'll ping @jonp as well, he is an employee of Limetech, and has a lot of experience with virtual machines.
