Hey,
This parameter
disk = ['file:/root/sol.dd,xvda,w','file:/root/sol-11_2_15_5_1-text-x86.iso,xvdb:cdrom,r']
works with qemu-traditional, but if I try with qemu-xen it
does not find the disk:
(d15) [2016-01-22 20:50:03] enter handle_19:
(d15) [2016-01-22 20:50:03] NULL

(d15) [2016-01-22 20:50:03] Booting from c980:0361
while with qemu-traditional:

It does work with Xen 4.4, but that is ancient. I hadn't yet
tried Xen 4.5 nor 4.6.
I am hoping one of you knows exactly which commit might have made
this change?
Note that the name is 'xvda', not 'hda'. Thanks!

You are good.
That was it.
CC-ing Anthony - are you OK if the patch was reverted?

And I dug in the thread.
There is a bit of problem here. This patch breaks some existing guests (Solaris 11.2
for example). It assumes that when running under Xen it would only use PV drivers.
Which is fine - except that the bootup part (GRUB2) is all done using QEMU - and
if the guest config has 'xvda' then SeaBIOS won't see the disk anymore. QEMU
traditional will still show the disk.
Ideas how to deal with the existing guests?
P.S.
Solaris OS cannot run as PV guest, only HVM.

I'd prefer this not be reverted, and instead use 'hda' in your config. Unless
you know of another way for libxl apps to request a xen virtual disk without the
accompanying emulated one.
