Hi all,

I'm trying to start a pvh guest on debian 8.2(whose kernel is 3.16.43-2+deb8u3) with xen 4.5.0, the guest is a compiled linux 4.12.10 kernel(pvh support enabled). However, the xen could not parse the config correctly, saying 
    xc: error: panic: xc_dom_core.c:877: xc_dom_parse_image: unsupported feature requested: Invalid configuration
    libxl: error: libxl_dom.c:583:libxl__build_pv: xc_dom_parse_image failed: No such file or directory
    libxl: error: libxl_create.c:1121:domcreate_rebuild_done: cannot (re-)build domain: -3

The problem is that when I change to linux 4.7, xen4.5.0 could successfully create the VM, although it got stuck when booting, I got only one line output,
    (XEN) irq.c: 380: Dom1 callback via changed to Direct Vector 0xf3

I've got one successful try with xen 4.9.0 and linux cloned from git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git

I wonder if pvh is not fully supported in xen 4.5.0? Do I have to switch to xen 4.9.0 to start a pvh guest?
