If should be possible to update the snv_85 domU using a BFU archive
that contains the fix for 6650717.
http://dlc.sun.com/osol/on/downloads/
I think the "current" BFU (from 20080331) already contains the fix.
And "b87" will have it, too. But "b87" is not yet available.
But the BFU update won't help much with installing a fresh snv85
domU from the optical installation media. You would have to update /
BFU the kernel bits that are booted from the optical media.
If you're impatient, you can use the kernel debugger to apply the
fix for 6650717 to the live snv_85 kernel that gets booted from
DVD:
# cat /tmp/solaris-exp
name = "solaris-exp"
memory = 512
vcpus = 1
kernel = '/boot/platform/i86xpv/kernel/unix'
ramdisk = '/boot/x86.miniroot'
bootloader = 'pygrub'
extra = '/platform/i86xpv/kernel/unix -kd - nowin -B
install_media=cdrom'
disk = [ 'file:/tmp/sol-nv-b85-x86-dvd.iso,6:cdrom,r' ]
vif = [ 'mac=2:35:a0:5e:c5:7a' ]
on_shutdown = 'destroy'
on_reboot = 'destroy'
on_crash = 'destroy'
On a 3.2 xen hypervisor (32-bit), it crashes. This is bug 6650717:
# xm create /tmp/solaris-exp -c
Using config file "/tmp/solaris-exp".
