routeros instalation is ok, but after installation of xen package, router doesn't boot
it reboots after loading image
is problem with cpu on this board ?
Version is 3.22 and cpu does not support kvm. I've tried linux and xen on the same board it worked. I think some compile options may prevent Mikrotik's Xen kernel to boot on that.
if you installed xen package and it booted up, that means that xen kernel is sarting correctly problem is with memory allocation. To create and run guest DomU, you need to reduce memory available to Dom0, and that is what is not working. Try some older version please.
