[Xen-users] Xen 4.8, qemu 2.12.0 - Live CDs fail to boot from 64-bit kernels

[Stephen Oberholtzer <stevie@xxxxxxxxx>]

Okay, I've been struggling with this for ages, and have enough data to come back here.

* Xen 4.8 ('xl info' outputs 4.8.4-pre, but it's Debian version 4.8.3+xsa267+shim4.10.1+xsa267-1+deb9u9) 

* QEMU emulator version 2.12.0 (Debian 1:2.12+dfsg-3)

Trying to boot a Knoppix or Debian Live ISO inside an HVM fails: CD-ROM emulation fails.

What's extremely strange is that 32-bit kernels boot just fine, it's just 64-bit kernels that have a problem.

Furthermore, the kernels don't exhibit this problem if I run qemu directly (no Xen acceleration).

Having libata dump the IDENTIFY data had a most curious result: all zeroes.
