I made certain changes to my configuration file. Instead of= trying to use a disk, I want to the guest domain up from=C2=A0 ramdisk ima= ge. My new configuration file looks like

"
name =3D "an= droid"

kernel =3D "/home/root/android/kernel"
ramd= isk =3D "/home/root/android/ramdisk.img"
#bootloader =3D "= ;/usr/lib/xen-4.4/bin/pygrub"

memory =3D 512
vcpus =3D 1
=
device_model_version =3D 'qemu-xen-traditional'

extra = =3D "console=3Dhvc0 rw init=3D/bin/sh earlyprintk=3Dxenboot"
<= br>"

I'm able to create a guest domain as well.

Howe= ver I'm not able to access the guest console. 'xl console androi= d' shows nothing, but using 'Ctrl + 5' or 'Ctrl + ]'= ; closes the console. Am I missing something here?

I have used the below configuration file for creating a guest domain.
"
name =3D "ubuntu"

kernel =3D "/home/root/ubuntu/vmlinuz"
ramdisk =3D "/home/root/ubuntu/initrd.gz"
#bootloader =3D "/usr/lib/xen-4.4/bin/pygrub"

memory =3D 1024
vcpus =3D 1

device_model_version =3D 'qemu-xen-traditional'
I would suggest to run the stuff without this line.

disk =3D [
=C2=A0 =C2=A0 =C2=A0'/dev/vg0/domu0,raw,xvda,rw'
Do you really have "/dev/vg0/domu0" in your dom0?
=C2=A0 =C2=A0 =C2=A0 =C2=A0]

"

But when I try to create the guest domain using xl create command,I get the= below error.

 /root@omap5-evm:/# xl create -d -c /etc/xen/config.d/ubuntu.cfg/
Please try adding ` xl -vvvv create -d -c /etc/xen/config.d/ubuntu.cfg` for= getting more output./

Any input would be highly appreciated

BTW, what is your dom0 system? Does it have bash?
Long time ago, we had busybox in dom0, and used https://marc.info/?l=3Dxen-devel&m=3D146358920813936= &w=3D4 to workaround block device creation issues.
