Hi, everybody,
Went to give PVH a try, seeing as we have 4.4 and 3.14 now in f20, but:
# grep XEN.*PV /boot/config-3.14.4-200.fc20.x86_64 CONFIG_XEN_PVHVM=y # CONFIG_XEN_PVH is not set CONFIG_XEN_HAVE_PVMMU=y
Posting my notes here, in case anybody else is trying it and wants to compare. I haven't yet had luck getting a pvh domU to launch. I think I'm doing what the documentation calls for, but clearly something is missing.
Current bits are up here: https://www.bfccomputing.com/downloads/fedora/xen/f20/
I've got Xen 4.4 booting and a kernel built with PVH support, but when starting a domU with 'pvh=1' I get:
xc_dom_parse_image: unsupported feature requested
Could you also include 'xl dmesg' please?
and the domain fails to build. I did verify that BUILD/kernel-foo/.config is getting the entry, and it sure looks like the symbols are in the kernel:
[root@librescu xen]# grep -i pvh /boot/config-3.14.4-200.xenpvh.fc20.x86_64 /boot/System.map-3.14.4-200.xenpvh.fc20.x86_64 /boot/config-3.14.4-200.xenpvh.fc20.x86_64:# Linux/x86_64 3.14.4-200.xenpvh.fc20.x86_64 Kernel Configuration /boot/config-3.14.4-200.xenpvh.fc20.x86_64:CONFIG_XEN_PVHVM=y /boot/config-3.14.4-200.xenpvh.fc20.x86_64:CONFIG_XEN_PVH=y /boot/System.map-3.14.4-200.xenpvh.fc20.x86_64:ffffffff81004340 t xen_pvh_set_cr_flags /boot/System.map-3.14.4-200.xenpvh.fc20.x86_64:ffffffff816e04d0 T xen_pvh_secondary_vcpu_init /boot/System.map-3.14.4-200.xenpvh.fc20.x86_64:ffffffff81d2a0a9 t xen_pvh_gnttab_setup /boot/System.map-3.14.4-200.xenpvh.fc20.x86_64:ffffffff81e5fd48 t __initcall_xen_pvh_gnttab_setup1 [root@librescu xen]# uname -r 3.14.4-200.xenpvh.fc20.x86_64
So, I'm not sure what's up. I added "loglvl=all guest_loglvl=all" to grub and can get another reboot in this weekend to see if there's any more info logged.
It also looks like I should update my 4.4 tarball to the stable-4.4 branch for non-broken guest shutdowns (but one step at a time).

I put the current one here in case there's anything useful:
but I'll also add the debug-level 'xl dmesg' after I get a reboot.

OK. Nothing much show up in the log - except that you are using XSM and I have not been building that when testing/developing (oops).
Could you try to rebuild Xen but without XSM just in case it is something in there?
Thanks!
