There is no one pv backend, it is a per device type thing. For disk, blkback (in backend kernel driver) is best if your guest disks are backed by raw disks (e.g. lvm volumes in the backend), qdisk (from qemu-upstream) is best if your guest disks are backed by something more complex, like a qcow2 file. For network netback (in kernel backend driver) is best. For PVFB, PVKBD and PVMOUSE qemu-upstream is the best (only?) backend. There is no qemu-xen-trad on ARM, I don't expect anyone to port it and I wouldn't expect those patches to be accepted anyway. > Is there any guild doc to get it work on arch arm? I'm not sure what "it" refers to here. PV backends generally are part of all the docs on the wiki explaining how to get Xen to work, there is not generally a separate guide for them since they are part of the core concept. qemu-upstream is built along with Xen on ARM for a while (not 4.4, 4.5-rcN should be fine), the in kernel backends have been available for longer than Xen on ARM has been.
