From 8d84be5b557b27e9cc53e48285aebad28a48468c Mon Sep 17 00:00:00 2001

Subject: [PATCH 03/55] libxl: Use XEN_LIB_DIR to store bootloader from pygrub
In osstest, the jobs using pygrub on arm64 on the branch linux-linus
started to fails with:
[Errno 28] No space left on device
Error writing temporary copy of ramdisk
This is because /var/run is small when dom0 has only 512MB to work
with, /var/run is only 40MB. The size of both kernel and ramdisk on
this jobs is now about 42MB, so not enough space in /var/run.
So, to avoid writing a big binary in ramfs, we will use /var/lib
instead, like we already do when saving the device model state on
migration.
