Please make sure you have in that kernel configuration XEN support enabled (together with hypervisor console support).

Hello Andrii,

>> What kernel d= o you use for DomU? Please make sure you have in that=20 kernel configuration XEN support enabled (together with hypervisor=20 console support).

I use a 3.15 kernel (git://git.kernel.org= /pub/scm/linux/kernel/git/torvalds/linux.git) with the following config= s enabled for Xen support.
CONFIG_XEN_DOM0=3Dy
CONFIG_XEN=3Dy
CONFIG_XEN_BLKDEV_FRONTEND=3Dy
CONFIG_XEN_BLKDEV_BACKEND=3Dy
CONFIG_XEN_NETDEV_FRONTEND=3Dy
CONFIG_XEN_NETDEV_BACKEND=3Dy
CONFIG_INPUT_XEN_KBDDEV_FRONTEND=3Dy
CONFIG_HVC_XEN=3Dy
CONFIG_HVC_XEN_FRONTEND=3Dy
CONFIG_XEN_DEV_EVTCHN=3Dy
CONFIG_XEN_BACKEND=3Dy
CONFIG_XENFS=3Dy
CONFIG_XEN_COMPAT_XENFS=3Dy
CONFIG_XEN_SYS_HYPERVISOR=3Dy
CONFIG_XEN_XENBUS_FRONTEND=3Dy
CONFIG_XEN_GNTDEV=3Dy
CONFIG_XEN_GRANT_DEV_ALLOC=3Dy
CONFIG_XEN_PRIVCMD=3Dy

In fact, it is the same kernel as that of dom0, just to che= ck if Xen is properly configured.

Also, I had previously= tried with a kernel image with no Xen support and the results were quite s= imilar - guest domain gets created and is shown in a running state as per <= i>'xl list' , however 'xl console' shows nothing= but hangs until I press Ctrl+5 .

Thanks and Regard= s,

I made certain changes to my configuration file. Instead of trying to use a= disk, I want to the guest domain up from ramdisk image.
Its quite wise idea to sort out problems.

My new configuration file looks like

"
name =3D "android"

kernel =3D "/home/root/android/kernel"
ramdisk =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"= ;

"

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

However I'm not able to access the guest console. '/xl console andr= oid/' shows nothing, but using 'Ctrl + 5' or 'Ctrl + ]'= closes the console. Am I missing something here?
What kernel do you use for DomU? Please make sure you have in that kernel c= onfiguration XEN support enabled (together with hypervisor console support)= .
