Thank you for your answer! Adding console=hvc0 indeed provides kernel output serial console. Looking at the log message, I found dom0 kernel failed to initialize a lot of device drivers (network cards, raid cards, etc).Is it related to iommu?

At the moment, the IOMMU is not hidden from dom0. So Linux may try to use it. However, IIRC, it is only becoming a problem when booting a guest.
