I have properly packaged a split off of xen support in grub2 for Centos 7.
No more segfaults.
I have not seen anyone attempt to package this starting with the official C7 
SRPM from the vaults.

 There is some interest lately in making a self-contained grub2 boot image - 
call it pvgrub2, used for booting paravirtual domU in xen where a grub2 config 
is installed.
First attempt------------------
I first tried using the grub2*.src.rpm from the C7 vault.
I configured as shown 
belowhttps://blog.xenproject.org/2015/01/07/using-grub-2-as-a-bootloader-for-xen-pv-guests/
for headers, I used xen-devel, xen-libs, xen-licenses from a recent build I 
didhttp://107.185.144.55/xen/cent7/dom0/RPMS/stable-4.5/mock/
this gave a segfault from grub2-mkimage with a cmdline 
like/usr/bin/grub2-mkimage  -O x86_64-xen   -C auto  -d 
/usr/lib/grub/x86_64-xen -c ./grub-bootstrap.cfg     -m ./memdisk.tar     -o 
./grub2-x86_64-xen.bin -v  ext2 fat file font fshelp gzio halt hashsum help 
legacycfg linux loadenv loopback part_dvh part_gpt part_msdos part_plan 
part_sun xfs xnu_uuid xnu_uuid_test xzio
the image would finish if I cut down the module list to about 8 or less 
modules. This is not enough for a useful image .

Second Attempt----------------In the same build env, I started with the git 
clone (see link). Now when running grub-mkimage I included all the modules 
in/usr/lib/grub/x86_64-xen/ and the image formed without error and works as 
expected as a xen bootloader.
The only difference in the two builds is the size of grubX-mkimage: one is 
stripped and the other not. Using the official grub2 C7 packages failed and a 
rogue build from git worked.
