X-Git-Tag: archive/raspbian/4.11.1-1+rpi1~1^2~66^2~755

-xen-attach is needed for pvh boot with qemu-xen

Currently the boot of a pvh guest using the qemu-xen device model
fails with the error
xen emulation not implemented (yet)
in the qemu-dm log file. This patch adds the missing -xen-attach
argument.
