Doesn't look like you have altp2m enabled in Xen.

And this is my /etc/default/grub file:

If you change this file, run 'update-grub' afterwards to update

/boot/grub/grub.cfg.

For full documentation of the options in this file, see:

info -f grub -n 'Simple configuration'

GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=0
GRUB_DISTRIBUTOR=lsb_release -i -s 2> /dev/null || echo Debian
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""

Uncomment to enable BadRAM filtering, modify to suit your needs

This works with Linux (no patch required) and with any kernel that obtains

the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)

#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"

Uncomment to disable graphical terminal (grub-pc only)

#GRUB_TERMINAL=console

The resolution used on graphical terminal

note that you can use only modes which your graphic card supports via VBE

you can see them in real GRUB with the command `vbeinfo'

#GRUB_GFXMODE=640x480

Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux

#GRUB_DISABLE_LINUX_UUID=true

Uncomment to disable generation of recovery mode menu entries

Uncomment to get a beep at grub start

If you booted Xen with that command line and altp2m is not enabled that means your CPU doesn't support EPT. Try a different system.

Also sir the commands mentioned on drakvuf.com is not working with the system only having SSD. when i upgrade the grub using command update-grub and reboot the system for booting it in xen hypervisor then my system not booted up. I tried it many times then i tried it with the laptop having HDD it worked, same commands i followed.

Thanks & Regards
