Hmm, Usually, you can boot very well even if the hostname is not set - you just need to tftp server address.
well the dns name has been set to that address in BIND
DHCP entry is like:

       group {
              # PXE-specific configuration directives
              next-server tftpserver;
              filename "linux-install/pxelinux.0";
# You need an entry like this for every host
              # unless you're using dynamic addresses
               host vm00 {
               hardware ethernet 00:0C:xx:xx:xx:xx;
               fixed-address xxx.xxx.xxx.xxx;
               }
       }


also i do an ifconfig and everything to doublecheck before reboot and also all the system messages during install and everything seems to match up.
pings fine and no funny logs
