Below are my grub setup notes, I use:
GRUB_CMDLINE_LINUX_DEFAULT="rootwait"
2. ###### Fix Grub Settings ######
2.1 ### Fix grub setup so that the first kernel is a xen kernel (required).

2.2 ### Add entries to /etc/defalult/grub
# cat >> /etc/default/grub <<EOF
# Disable OS prober to prevent virtual machines on logical volumes
# from appearing in the boot menu.
GRUB_DISABLE_OS_PROBER=true
# Xen boot parameters for all Xen boots
#GRUB_CMDLINE_XEN=""
# Xen boot parameters for non-recovery Xen boots
# (in addition to GRUB_CMDLINE_XEN)
#GRUB_CMDLINE_XEN_DEFAULT=""
EOF
2.3 ### Adjust grub timeout
### Note for IBM x346 server:
###
### I had to change the default grub delay from 5 seconds to 10, in
/etc/default/grub
###
### With the standard 5 seconds, the Dom0 wouldn't boot and I would
### get a CPU panic with reboot every time.
GRUB_TIMEOUT=10
### this continued to be a problem later.... on another machine
### the best fix was to adjust a different line in /etc/default/grub
### it originally has "quiet", but I didn't want quiet, I did want
rootwait
### to fix this problem
GRUB_CMDLINE_LINUX_DEFAULT="rootwait"
2.4 ### Update Grub Setings ######
# update-grub2
