(XEN) Command line: vtd=1 iommu=1 dom0_mem=512M loglvl=all guest_loglvl=all

"vtd=1" is old/obsolete parameter, it's not used anymore.
Also "iommu=1" is the default in Xen 4.0.0, so that's not needed either :)

"iommu=verbose" can be used to get more debugging output, 
especially if IO virtualization doesn't get enabled.
