Subject: libxl: Makes libxl be able to call Qemu upstream for XenPV guest.
X-Git-Url: https://dgit.raspbian.org/%22http://www.example.com/cgi/%22/%22http:/www.example.com/cgi/%22?a=commitdiff_plain;h=5f258c9e4372a2c19e3809ccc82906f1ca16451c;p=xen.git

libxl: Makes libxl be able to call Qemu upstream for XenPV guest.

In libxl_build_device_model_args_new:
  - Adds -xen-attach options to the list of arguments to Qemu.
  - Adds -vga xenfb options when vnc and sdl are not set.
  - Remove disk list from the command line for XenPV as they will be
    read from xenstore by Qemu.
