A network install is the best option but you can always add and remove devices using virsh
Have a look in the man page for virsh at attach-disk and detach-disk

All working a treat: created the guest (fully virtualised - I have no time for Xen), setup disk space in a 6Gb file, gave it a name, and pointed the installation source to be the first of 6 .iso files for Centos 5 installation

How the blazes is one supposed to tell it where to get the file?
I'm completely stuck! I thought this was supposed to work with .iso files and I wouldn't have to burn 6 CDs. But what happens now?
Last I read, the ability to change CD was "planned for the future."
You're better off using the DVD image. If you can find a .jigdo file and template (I think CentOS does it), then you don't have to download much of CentOS 5 again.
Or do a network install: nfs should work really well over a virtual LAN.
If you don't mind the bleeding edge, the latest release of libvirt supports connecting and disconnecting cdrom backing devices (or isos) from a fullvirt xen guest. The xen guest must have a cdrom device with no "source" line in its xml definition (unfortunately we don't support this with KVM yet although we plan to soon). If you call "virsh attach-device <domain> <device.xml>" where "device.xml" is an xml file with a complete device definition like so:
<disk type='block' device='cdrom'> <source dev='/dev/cdrom'/> <target dev='hdc'/> <readonly/> </disk>
then libvirt will attach your host cdrom device to the guest's cdrom device. Then to disconnect the cdrom, call "virsh attach-device <domain> <device.xml>" where "device.xml" is an xml file like the above, but with no "source" element.
The upcoming release of virt-manager (should be out today if it isn't already) has UI that supports this capability. Again, to be clear, this only works for fully virtualized Xen guests at the moment; we're working on adding it to kvm but have no idea when that will be available.
Hope this helps somewhat.
Take care, --Hugh
