Xen is booting properly here and the kernel hvc0 console is also working ([ 0.346199] console [hvc0] enabled) It seems that all your cores are ending up in idle in Linux (all ELR are at the same address). So you probably have a problem mounting a root filesystem or you network is not coming up. An other solution would be that you linux is missing the hvc0 console entry in inittab. I would suggest to try the following: - pass console=ttySC1 which is probably the second serial line of your board and connect to it to see if linux goes further - use an sdcard based or usb based root filesystem instead of NFS - add rootwait option But all in all Xen works well and you now have a linux boot issue probably not related to xen. Regards Bertrand PS: You might want to switch to xen-user mailing list instead of xen-devel :-)
