The Qemu -pflash option can be used to boot an emulated system from an emulated flash (NAND/NOR) device. Qemu needs to be patched for supporting this option and our current version in EmbeddedXen tree is not already patched for this support. We currently boot from an emulated harddisk interface (-had Qemu option).

To be short, you can ignore these options and remove them from the Qemu command-line. It is a remaining of older project in our scripts and we will remove them from the distributed scripts to not confuse the user.

Please use the provided startup scripts at the root of the EmbeddedXen tree (stv6h script in your case). You will thus have all necessary Qemu options configured correctly.

In your example, there are some errors / missing options compared to what we use in our scripts
- memory size is set to 128MB in your command line (-m 128) where we use 256MB
- you don't provide a disk image for the rootfs (-hda tools/rootfs/rootfs_v6.img)

Hope this helps
