linux xen 3.1.0 dom0 / solaris domU PV install from usb dvd reader
When trying to boot the OpenSolaris b75a dvd in a pv domU
(using the linux phy:/dev/cdrom device as the source for the
boot media), running on an Ubuntu 7.10 x86_64 dom0 box
with xen 3.1.0 hypervisor, using the following config file...
=======================================#
# Hostname
#
name = ''solaris-install2''
#
# Kernel + memory size
#
kernel = ''/boot/platform/i86xpv/kernel/amd64/unix''
ramdisk = ''/boot/amd64/x86.miniroot''
bootloader = ''pygrub''
extra = ''/platform/i86xpv/kernel/amd64/unix -kd - nowin -B
install_media=cdrom''
memory = ''1024''
#
# Disk device(s).
#
disk = [ ''phy:/dev/cdrom,6:cdrom,r'' ]
#
# Networking
#
vif = [ ''mac=ed:b7:8e:10:3b:b7'' ]
#
# Behaviour

on_poweroff = ''destroy''
on_reboot = ''restart''
on_crash = ''restart''
=======================================
... Solaris prints the following to the console and fails to install:

This doesn''t happen when I try to boot from an iso image file,
like this:
disk = [
''file:/volumes/xen-install-images/solaris/solaris.iso,6:cdrom,r''
]
In the "file:" case, xdf_oe_change() gets an
XenbusStateInitWait and XenbusStateConnected event, but
no XenbusStateClosed. And the OpenSolaris installer is able to
find the installation media CD just fine.
Is this a linux / dom0 bug?
