When booting into dom0=pvh, using the serial console prevents dom0 from booting. Serial works until Xen tries to hand off to dom0. The specific crash varies with the arguments passed to iommu:
iommu=1,debug console=com1 com1=115200,8n1 Xen goes into an infinite loop iommu=1 console=com1 com1=115200,8n1 Xen either receives an NMI in process_pending_softirqs or gets stuck in __sync_local_execstate iommu=1 dom0 boots fine, but USB doesn't work (as others have recently posted about). I'm using xen staging and linux xen/tip. Example logs for the first two cases are attached. Connor Davis
