I am trying to get xen running on an arndale Exynos5250. I think I am close to success because I can boot the hypervisor and interact with the debug console and I don't see any errors. I can switch the debug console from xen mode to Dom0 mode by pressing CTRL-a three times, however I am not prompted to login to Dom0 and I am not able to type any commands. I am unsure if the expected behavior is to receive a login prompt when I switch to Dom0 mode or if I should be getting output on the HDMI and that is where I would login to Dom0. I have attached the putty log showing how I boot with all of the environment variables I am using and after booting I pressed '*' to print all diagnostics. Here are my steps so far. I have done all of the compiling on the arndale board running the linaro prebuilt image from: https://releases.linaro.org/14.03/ubuntu/arndale/arndale-saucy_server_20140323-616.img.gz I have followed the instructions here: http://wiki.xen.org/wiki/Xen_ARM_with_Virtualization_Extensions/Arndale I initially got the following error compiling Linux: LD sound/built-in.o MK_FW firmware/edid-1920x1080.fw.gen.S make[1]: *** No rule to make target `firmware/edid-1920x1080.fw', needed by `firmware/edid-1920x1080.fw.gen.o'. Stop. make: *** [firmware] Error 2 so I changed the value set in /linux/linaro/configs/lt-arndale.conf from CONFIG_EXTRA_FIRMWARE="edid-1920x1080.fw" to CONFIG_EXTRA_FIRMWARE="" That is the only thing I did that deviated from the instructions. My initial thought was that I needed to add a getty process on COM3, so that when I switched to Dom0 mode I could login. This page seems to agree with me: http://wiki.xenproject.org/wiki/Xen_Serial_Console I tried to do so by creating a ttyS2.conf file under /etc/init/ that read as follows: start on stopped rc RUNLEVEL=[2345] stop on runlevel [!2345] respawn exec /sbin/getty -8 115200 ttyS2 with that in place I was still not prompted to login but it had an effect because the serial connection would become unresponsive after a few minutes.
