Hi!
as I've reported earlier -- part of my testing of Xen 4.13 RC2 failed
in a massive way with Dom0 never coming up. I've traced that problem
to the option that we're using to boot Xen:
efi=no-rs
We've been using this option for quite sometime and Xen 4.13 RC2
is the first one that seems to make Dom0 boot fail with this option
present (note that RC1 was fine).
I was wondering whether there were any changes in the areas related
to UEFI in Xen that may have triggered this.
Here's the boot line that works with RC2:
dom0_mem=1024M,max:1024M dom0_max_vcpus=1 dom0_vcpus_pin smt=false
adding efi=no-rs make Dom0 boot process fail:
efi=no-rs dom0_mem=1024M,max:1024M dom0_max_vcpus=1 dom0_vcpus_pin smt=false
Attaching xl info and dmesg just in case
Thanks,
Roman.
