I was worried about spamming the list by sending the full logs but if that is
likely to have the most useful
information then here we go...
xen-4.4.3.gz is installed as bootx64.efi but that fails and so it drops to the
firmware where I start a shell
and then execute xen-4.5.1.efi. I've just noticed the firmware sees the system
with 16Gb RAM despite the guest
configuration being memory=20480 but changing that to 16384 did not change the
behaviour. Xen also seems to
only see 1 cpu when the configuration is vcpus=4. iommu=1 is set on the
command line because this is an image
from a physical server but no iommu is detected, changing to 0 has no effect.
If I boot the hvm without xen
using the same kernel I can get to the ramdisk shell, the log for that boot is
the second one below.
The complete xen configuration file is:
name = "nvdom0"
builder = "hvm"
vif = [
"bridge=ovswan,mac=00:16:3e:01:3d:23",
"bridge=ovslan,mac=00:16:3e:02:3d:23"

#memory = 16384
