This used to work for me with 2.2.2. something broken here.
I'm not really familiar with what do "liveiso:/" and "live:/" mean or 
what the exact problem is but I've tried to set ovirt-node in pxe, I 
used a pxeboot script (taken from another rpm since I couldn't find one 
in ovirt-node package), the script created for me the needed files 
(ramdisk, kernel and cfg files), and when I've booted from that pxe 
entry - I found myself in the same problem, got into that shell with the 
same error message - only my "liveiso:/" pointed to a different path.

I solved that by changing the "liveiso:/blah/blah/blah/ovirt-node.iso" 
in the kernel path to "live:/ovirt-node.iso", for a backup I copied the 
ovirt-node.iso file to the same directory where the aforementioned 3 
files reside, it worked!
