How were your qemu vms created?  Was it by direct invocation of 'qemu'?
 If so, you _might_ be able to teach libvirt about those vms by using
'virsh qemu-attach $pid', but it depends on the vm having been created
with a proper monitor connection.

In general, libvirt is better suited to managing vms created via libvirt
interfaces (virt-manager is only one of many programs that uses libvirt
interfaces for creating a vm) than it is for managing random vms created
via direct command-line invocation of qemu.

The 'virsh domxml-from-native' command might help you in creating a
libvirt XML representation that matches what you are currently passing
directly to qemu, although that area of code is not the best-maintained
at the moment.
