Xen-git domains not starting on boot, but start fine afterward[SOLVED]

I am running xen-git 4.4. To start my domain with systemd I softlinked my config file (/etc/xen/conf/utm9.cfg) to /etc/xen/auto and enabled xendomains in systemd. My VM doesn't start successfully and I see the following in the journal:

Aug 23 19:14:23 adamwest xendomains[268]: /etc/xen/scripts/xendomains: line 29: LOCKFILE: command not found
Aug 23 19:14:23 adamwest xendomains[268]: touch: cannot touch '': No such file or directory

Aug 23 19:14:23 adamwest xendomains[268]: ..failed

It appears that it can't see it's disk (odd as it should be /dev/sda6, the same drive it is booting from).

My config looks like so:

# =====================================================================
# Example HVM guest configuration
# =====================================================================
#
# This is a fairly minimal example of what is required for an
# HVM guest. For a more complete guide see xl.cfg(5)

#kernel = '/usr/lib/xen/boot/hvmloader'

# This configures an HVM rather than PV guest
builder = "hvm"

# Guest name
name = "utm9"

# 128-bit UUID for the domain as a hexadecimal number.
# Use "uuidgen" to generate one if required.
# The default behavior is to generate a new UUID each time the guest is started.
#uuid = "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"

# Enable Microsoft Hyper-V compatibile paravirtualisation /
# enlightenment interfaces. Turning this on can improve Windows guest
# performance and is therefore recommended
#viridian = 1

# Initial memory allocation (MB)
memory = 4096

# Maximum memory (MB)
# If this is greater than `memory' then the slack will start ballooned
# (this assumes guest kernel support for ballooning)
maxmem = 4096

# Number of VCPUS
vcpus = 1

# Network devices
# A list of 'vifspec' entries as described in
# docs/misc/xl-network-configuration.markdown
vif = [ 'mac=08:0b:27:c2:b7:e4,model=e1000,bridge=xenbr0', 'mac=08:0b:27:20:09:59,model=e1000,bridge=xenbr1' ]

# Disk Devices
# A list of `diskspec' entries as described in
# docs/misc/xl-disk-configuration.txt
disk = [ '/dev/sda6,raw,hda,w' ]

#device_model = 'qemu-dm'

# Guest VGA console configuration, either SDL or VNC
sdl = 0
vnc = 1
vnclisten="10.144.0.255"
vncpasswd=*CENSORED*
usbdevice='tablet'
acpi=1
apic=1
stdvga=0
serial='pty'

on_xend_stop = 'shutdown'
on_xend_start = 'start'

Once it is booted fully I can run sudo systemctl start xendomains and everything is fine... Any ideas on why this would happen? It is very annoying to have to manually log in each boot to start the Xen dom.

Re: Xen-git domains not starting on boot, but start fine afterward[SOLVED]

Switched back to regular Xen after a rebuild and all if working as expected... Not really solved, but no longer an issue.
