Re: Utility of PV on non-obsolete hardware

	hello.  Below is a config file for bringing up an HVM domU host under
xen3.3 with a serial console.  I've used this with FreeBSD and NetBSD-4.x.
I have FreeBSD-11.x running  with this setup, so although the xen
installation is quite old, I'm able to run modern versions of domU guests.
Will this help get some documentation going?

<cut here for xen33-dom0-hvm.conf>

# Python configuration setup for 'xm create'.
# This script sets the parameters used when a domain is created using 'xm create'.
# You use a separate script for each domain you want to create, or 
# you can set the parameters for the domain on the xm command line.

# Kernel image file.
kernel = "/usr/pkg/lib/xen/boot/hvmloader"


# Initial memory allocation (in megabytes) for the new domain.
memory = 8192

vcpus = 4

# A name for your domain. All domains must have different names.
name = "YourDomain"

#Network interface. By default emules a realtek 8139. For a NetBSD guest you
# have to disable re(4) and let rtk attach to use it.
# ne2k_pci emulates a pci ne2000 clone; this his cpu-hungry in dom0
# pcnet emulates a AMD PCnet-PCI controller; but it corrupts packets with
# pcn(4) under NetBSD.

# Define the disk devices you want the domain to have access to, and
# what you want them accessible as.
# Each disk entry is of the form phy:UNAME,DEV,MODE
# where UNAME is the device, DEV is the device name the domain will see,
# and MODE is r for read-only, w for read-write.
# For hvm domains you can only use hda to hdd. You can set extra types
# (e.g. cdrom)

disk = [ 'file:/var/xen/domus/YourDomain/disk0,ioemu:hda,w', ]

# The following line creates 2 disks, a boot (install) disk and the system
# disk.  use this to recover from a disaster.  System disk shows up as ada1
# Root filesystem is ada1s1a (BB 08/31/2018)
# The cdrom file can be an image suitable for writing to a flash disk
# and should be bootable.

# By default, 'xm create' will try to open an X window on the current display
# for the virtal framebuffer. You can have the virtal framebuffer in vnc
# instead, and connect using a vnc client (using localhost:$vncdisplay)
# If vncunused is set to 1 (this is the default value), vncdisplay
# will be set to the first unused port; so it's recommended to
#vnc = 1
#vncdisplay = 0
#vncunused = 0

#Xen emulates a PS/2 mouse, but the pointer in the guest has difficulties
# tracking the absolute position. Xen can emulate a USB tablet in addition
# to the mouse which will report the absolute position of the pointer,
# and make the mouse much easier to use.
