- do you wnat to setup an ovirt-node, or just install vdsm on plain 
fedora 17?
sounds like the latter, but if you want to use fake-qemu, ovirt-node is 
much harder than just using a fedora 17.

for using plain fedora 17 as a guest, you just need to:
option 1:
- yum install vdsm vdsdsm-hook-faqemu
- vi /etc/vdsm/vdsm.conf and set vars.fake_kvm_support=True
- now simply add the host from web admin (hosts-->add host)
note: you may need this patch if not in your version of vdsm already:
http://gerrit.ovirt.org/#/c/5611/

option 2: if your host is fedora 16 and above, just use nested 
virtualization, and your virtual host would behave like a normal one (i 
still need to try this one out)
i.e., just add the virtual host from web admin (hosts-->add host)

I assume another step would be needed here (at least configuring the 
guest in libvirt to have nested virtualization), but i haven't tried 
this one yet to know what it is.
