CentOS virt - Mar 2008 - error installing Xen guests on CentOS 5.1 x64 - could not read tty from store

Hi all

I keep on getting this error when I try and install a Xen guest on a 
CentOS 5.1 x64 server with Xen installed from the repositories:



[root at gimbli ~]# virt-install sdl=0 vnc=0 nographic=0 -v 
--location=http://intranet/kickstart/cPanel/centos/5.1/32/os/i386/ 
--ram=256 --file-size=10 --file=/home/vm/vps07.img --name=vps07
libvir: error : configuration file syntax error: expecting an assignment
Would you like to enable graphics support? (yes or no) no
