Is it possible to install f16 final tc1 using only vmlinuz+initrd ?

[Gianluca Cecchi]

Hello,
is it expected to work a command such as this, after downloading
vmlinuz and initrd for f16 final tc1 (x86_64):

virt-install --os-type=linux --os-variant=fedora16 --boot
kernel=/tmp/f16tc1/vmlinuz,initrd=/tmp/f16tc1/initrd.img -r 1024
--name f16 --disk=/var/lib/libvirt/images/f16.img --network
network=default --virt-type=kvm

?
I'm running it from a system with fedora 15 + virt-preview repo.
But I get an error about
unable to read package metadata

Do I have to install anything else locally?
It seems to me that network has been configured correctly inside the guest...

Thanks in advance,
Gianluca
