Best thing to do is write up a command-line config for your little
domain. Try this to get started (put your specifics where needed):
kernel = "/usr/lib/xen/boot/hvmloader"
builder='hvm'
memory = 512
name = "MyDomain"
guest_os_type = 'linux'
vcpus=1
vif = [ 'type=ioemu, bridge=xenbr0' ]
disk = [ 'phy:/dev/vg0/lv3,hda,w', 'file:/tmp/rescue.iso,hdc,r' ]
boot="dcna"
vnc=1
vncconsole=1
vncpasswd=''
serial='pty'
This should boot into d=cdrom first, then c=hard disk second, followed
by n=network (PXE) third, followed by a=floppy last.

Not sure which screen you are talking about here, still using
virt-manager? Drop it and start writing config files.
The options are documented in the examples in /etc/xen directory.

Good fore thought, that'll save a step later.
