Hi, I have installed Xen-4.1.4 on existing server where the VM''s are running. After I have installed this Xen version the Xen HVM VM''s with Ubuntu are not booting well and its throwing the below error message while booting up, IO-APIC + timer doesn''t work! Boot with apic=debug and send a report. Then try booting with the "noapic" option If I boot with noapic then its booting fine. May I know what could be causing the issue to refuse boot as normal? Also does the VM will get any issues if we boot with noapic? _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users
