Exactly. The reason for this: VMs come and go, diskless setup on client is much easier to accomodate with that. But general services provided to all VMs (DHCP, DNS, HTTP cache/proxy) belong to the "host". > If you're after that septup, I'm not sure if it's possible...

Basically, is there is a way to tell the boot scripts running on the client to ignore the IP of the boot server, and try to mount NBD somewhere else? Can this be done via kernel parameters that I set in the pxelinux.cfg? What I am trying to achieve in general: There is a headless host running various VMs. There is a separate PC (or several of them) used for interactive stuff. Once turned on, the PC gets the PXE boot menu from the host. Then, either local boot (from PC's own HD), or a diskless boot may be chosen depending on the purpose. Diskless boot may target one VM or another as provider of root filesystem and applications. But the boot server is always the same, the "host". Ideally all I had to do to enable another booting method, would be to copy necessary image files (kernel, initrd) to the TFTP directory on the host, and update the pxelinux.cfg menu items. So IMHO this could be considered for LTSP as a feature: specify NBD or NFS root path in the kernel boot parameters obtained from pxelinux.
