 I got an error. I edited the files that you said and changed "gdm" to "gdm3" :

Then I used below command :xen-create-image --size=4Gb --swap=512Mb --ip=172.30.9.21 --netmask=255.255.255.0 --gateway=172.30.9.254 --dir=/home/jason --hostname=linux1 --dist=jessie --role gdm
But when I run below command show me error :

I edited this file too :

and used below command :

But the command can't complete and show me an error :

Must I install any external packages? I installed "xdm" and "gdm" too but problem not solved :(

Edit /etc/xen-tools/role.d/gdm and /etc/xen-tools/role.d/gdm, replace
"xserver-xfree86" by "xserver-xorg" (/etc/xen-tools/role.d/gdm
probably also needs "gdm" replaced by "gdm3") and then add either
"--role xdm" or "--role gdm" (whatever you prefer) to your
commandline.

        Kind regards, Axel
