I'm trying to boot Xen 4.4 + Linux dom0 inside VMware Fusion. Xen 4.4 and Linux are both the stock versions that come with Ubuntu Trusty, i.e. Kernel 3.13.0-32-generic #57-Ubuntu SMP Xen 4.4.0-0ubuntu5.1 The boot process hangs during kernel boot at: "x86: Booted up 1 node, 1 CPUs" details here: http://tinypic.com/r/24fixcj/8 If I boot without Xen, it works fine, and nested virtualisation using KVM inside (rather than Xen) also works fine. Any ideas? -- Alex Bligh
