Re: [Xen-devel] Unable to create guest PV domain on OMAP5432
Hello Andrii, >> What defconfig are you based on? Do you have a device-tree support enabled? I use *omap2plus_defconfig* . Yes , device tree support is there and the dts file used is *omap5-uevm.dts>> *But it did not get a command line to setup console on hvc0, or the kernel crashed in earliest stages. Is there a way to debug which one of the above two possibilities has lead to the issue ? As I'm using the dom0 kernel image for my guest, is it still possible that it could be a kernel crash since it has already booted up for dom0.

Re: [Xen-devel] Unable to create guest PV domain on OMAP5432
Hello Andrii, >> What kernel do you use for DomU? Please make sure you have in that kernel configuration XEN support enabled (together with hypervisor console support). I use a 3.15 kernel (git:// 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. 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 .

Hello Konrad, Apologies for the incomplete mail. Adding to the previous reply; >> not allocate order=18 extent: id=4 memflags=0xc0 (0 of 1)libxl: error: > looks like it could not allocate memory? In my configuration file, i had used "memory=1024" . However if I use any value <=512 , the above error log is not seen. However the rest of the logs appear and it is still unable to add disk devices.

[Xen-devel] Unable to create guest PV domain on OMAP5432
Hello all,
I'm trying to implement Xen hypervisor support on OMAP5432.I have followed
the steps as in
https://wiki.xenproject.org/wiki/Xen_ARM_with_Virtualization_Extensions/OMAP5432_uEVM
for the initial setup. I'm able to see the domain 0 successfully up.
