So how are you actually trying to install F17?
I tried:
virt-install --name F17 --ram 1024 --disk /dev/vg_guest/f17_32 --paravirt 
--location http://build/tftpboot/f17-i386/

and it showed the text console, and then rebooted thinking it was complete.
When using a manual guest config:
append="console=hvc0 loglevel=8 root=http://build/tftpboot/f17-i386";
maxvcpus = 2
vcpus = 2
disk = ['phy:/dev/vg_guest/f17_32,xvda,w']
vif = [ 'type=netfront, bridge=switch' ]
vfb = [ 'vnc=1, vnclisten= ,vncunused=1']

I get this:

so is there a new syntax for the root parameter now that is a LiveCD?

Yes, the F17 install image is now a liveCD so you need to specify this on the boot command line. This may be as simple as replacing root= with root=live:
