difficult for the audience to help you without any information about
your hardware and without any error messages.

i remembered some issues with some chip sets and EFI systems on ubuntu
xen. but this is some time ago, currently i have no ubuntu with xen running.

best regards
Ulf

I am running it on Proliant DL380 Gen10. There is no error message it just keep on restarting.

If I install CentOS 7 as first OS will that be a best alternative?

Before you wipe the disks and install another OS, you should take a
look at Xen "command line option":
https://xenbits.xen.org/docs/unstable/misc/xen-command-line.html

You could interrupt the boot process during the grub boot menu and set
the following "command line option" (boot argument) for the xen
hypervisor to stop it from rebooting on error:
noreboot=true

This should enable you to catch any error messages from Xen.
Since it should stop Xen from automatically rebooting on errors, take
care that you have physical/KVM/BMC access to the system since it
should freeze with Xen console access only (no network intefaces
initialized at that point).

Gruß, Linus
