It is a regression in comparision with FreeBSD v8.1 -- with the same Xen configuration FreeBSD v8.1 boots and runs adequately. With decreasing of amount of memory available in virtual machine to value below 1G, kernel hungs in endless loop without any output to console -- only 'xm destroy' is able to destroy the domain in question. >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
