Hi Rami, Ovirt-node package (iso) has everything you need to pxeboot into a stateless node. The way to create pxebootable ovirt-node images files is to:
1. first loop mount the ovirt node iso to say /mnt/iso 2. run /mnt/iso/LiveOS/livecd-iso-to-pxeboot <your-ovirt-node-iso> This will generate initrd0 and vmlinuz0 under /mnt/iso/tftpboot/. Plus the pxelinux.cfg/default. Copy those to proper directories in your DHCP/TFTP server. You should be set to pxeboot if you have done that before.
