I run Xen 4.6 Dom0 on an Opensuse Leap 42.1 server.Hardware is a SuperMicro X10SAT motherboard (http://www.supermicro.com/products/motherboard/Xeon/C220/X10SAT.cfm), with AMI v3 BIOS + "UEFI support"
Two issues exist with the SuperMicro EFI
(1) firmware EFI mis-mapping causing Xen PANIC on restart
(2) EFI variables not persistent across reboot
SuperMicro's development/support has been made aware of both issues;
Their response is that they won't/can't fix the problem.
I do NOT know if the problems exist with other SM boards' EFI implementations. Xen's EFI workarounds work to fix (1), not (2) (admittedly, not a xen-specific issue ... just crops up when GRUB2-ing your way to Xen boot) In #xen, it was suggested that I document the issue to the xen-devel ML, just for the record. Hence, detail follows:

Not clear whether they're using tianocore UEFI code.
Demonstration of (2), non-persistence of EFI boot vars:
@ OS shell, make changes to the MoBo's EFI NVRAM. E.g.,
efibootmgr -c -d /dev/sdg -p 2 -l
\\EFI\\opensuse\\xen-4.6.0_02-397.efi -L OpenSuse-Xen
efibootmgr -c -d /dev/sdg -p 2 -l \\EFI\\XEN\\xen.efi -L Custom-Xen
efibootmgr
BootOrder: 0001,0000
Boot0000* OpenSuse-Xen
Boot0001* Custom-Xen
efibootmgr -o 0,1
efibootmgr
BootOrder: 0000,0001
Boot0000* OpenSuse-Xen
Boot0001* Custom-Xen
after reboot, re-checking the EFI variables presented from the motherboard,
efibootmgr -v
(empty)
the vars are NOT persistent, and have been removed.

...
(XEN) 000009e29d000-000009e5b0fff type=3 attr=000000000000000f
tells us the fault is on an address in boot services code. Together with
(XEN) [2015-12-02 14:18:06] L2[0x0f2] = 000000009e3ff063
ffffffffffffffff
it also tells us that the L1 page table is in the same region of
memory. While not impossible, it's quite unlikely, and suggests the
firmware is actually playing with page tables in that runtime services
call (yet then oddly sets the mapping to no-execute, which is what
actually causes the fault). After all without /mapbs Xen wouldn't map
that area at all.
...
Considering your other reboot problem (after having added /mapbs) I
suppose "efi=no-rs" would take care of both issues at once. Please let
us know.

The "efi=no-rs" fix seems to, so far, be the most-complete workaround.
There's a recent, additional thread which also appears to be relevant to
the 'right' fix for this (these) EFI firmware issues,
[Xen-devel] [PATCH] x86/time: Don't use EFI's GetTime call by default
http://lists.xen.org/archives/html/xen-devel/2015-12/msg00159.html
wherein there appears to be some disagreement as to necessity/approach.
Finally, SM's had all of the above detail communicated to their EFI devs.
After a bunch of back & forth, SM confirmed that
-- EFI is claimed to be "supported" on this board
-- it ACKs that these issues are a result of firmware error
-- SM can't, or won't, fix it, and will instead rely on 3rd party
workarounds . I.e., from devs at Kernel/Xen/etc.
Futher comments included
"...
BIOS can't support the fixed boot order feature in this beta BIOS.
After clarifying with our BIOS team, either fixed boot order OR efi
variable boot order can support from the BIOS. If the BIOS supports the
efi boot manager, then BIOS can't support the fixed boot order feature.
Thank you for your understanding!
..."
which upon further clarification means that once updated, it will no
longer be possible to select/boot to non-EFI options, such as
'removable', or 'usb drive', or 'cd'.
Not particularly helpful.(By the by, anyone recommend particular H/W server/workstation mobo vendor that has well-implemented EFI support that's Xen-friendly?) _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
