[Fedora-xen] Problem with network install, network wrong

[John Summerfield]

I'm using the click-through wizard to try to network-install F8, 
fully-vertualised, on F8.

My dhcpd configuration gives special treatment to PXE clients which it 
recognises:
class "pxeclients"
         {
                 match if substring (option vendor-class-identifier, 0, 
9) = "PXEClient";
                 option vendor-class-identifier "PXEClient";
# At least one of the vendor-specific option must be set.       We set
# the MCAST IP address to 0.0.0.0 to tell the bootrom to still use
# TFTP (address 0.0.0.0 is considered as "no address")
#               option PXE.mtftp-ip 192.168.9.1; vendor-option-space PXE;
                 option PXE.mtftp-ip 0.0.0.0; vendor-option-space PXE;
         }

and later,

         pool {
                 allow members of "pxeclients";
                 default-lease-time 1800;
                 max-lease-time 3600;
                 range 192.168.9.150 192.168.9.169;
                 filename "/PXE/pxelinux.0";
         }

I  give etherboot clients special (different). treatment too.

class "Etherboot"
         {
                  match if substring (option vendor-class-identifier, 0, 
13) = "Etherboot-5.0";
                  option vendor-encapsulated-options 
3c:09:45:74:68:65:72:62:6f:6f:74:ff;
                  option vendor-class-identifier "Etherboot-5.0";
                  filename "tftpboot.vc";
         }

and IBM thin clients.

Unfortunately, virt-manager tells the user it's using PXE, but something 
tells the DHCPD server it's etherboot. Here's a bit of

For this application, the "boot rom" needs to claim it's PXE.

btw I can also recognise Macs (good to deal with openfirmware) Anaconda 
(a shame it won't use the filename I return), debian-installer
