I use a 3.15 kernel
(git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
<http://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git>)
with the following configs enabled for Xen support.
CONFIG_XEN_DOM0=y
CONFIG_XEN=y
CONFIG_XEN_BLKDEV_FRONTEND=y
CONFIG_XEN_BLKDEV_BACKEND=y
CONFIG_XEN_NETDEV_FRONTEND=y
CONFIG_XEN_NETDEV_BACKEND=y
CONFIG_INPUT_XEN_KBDDEV_FRONTEND=y
CONFIG_HVC_XEN=y
CONFIG_HVC_XEN_FRONTEND=y
CONFIG_XEN_DEV_EVTCHN=y
CONFIG_XEN_BACKEND=y
CONFIG_XENFS=y
CONFIG_XEN_COMPAT_XENFS=y
CONFIG_XEN_SYS_HYPERVISOR=y
CONFIG_XEN_XENBUS_FRONTEND=y
CONFIG_XEN_GNTDEV=y
CONFIG_XEN_GRANT_DEV_ALLOC=y
CONFIG_XEN_PRIVCMD=y
In fact, it is the same kernel as that of dom0, just to check if Xen
is properly configured.
What defconfig are you based on? Do you have a device-tree support enabled?
Also, I had previously tried with a kernel image with no Xen support
and the results were quite similar - guest domain gets created and is
shown in a running state as per /'xl list' /, however /'xl console/'
shows nothing but hangs until I press Ctrl+5 .
Your guest is created and XEN treats it as being running, you can see
this in `xl list`.
But it did not get a command line to setup console on hvc0, or the
kernel crashed in earliest stages.
