Hi all,

With the recent xVM putback of:

6851808 Stop delivering 32-bit dom0
http://bugs.opensolaris.org/view_bug.do?bug_id=6851808

we have stopped delivering 32-bit xen.gz, along with the disk and
networking backend drivers used in dom0.  This does not affect
32-bit domUs.

The rationale is explained in the bug report.

Other than upgrading to 64-bit capable hardware, for users still
interested in virtualization on 32-bit machines, the options are:

 * OpenSolaris Containers, if using the same kernel version in
   the guest and host (or using one of the branded zones if they
   support the version of Solaris you need)

 * VirtualBox for Linux, Windows and other guests operating systems

After this change, the error message you would see were you to try to
boot from an xVM grub entry on a 32-bit machine would look like:

---------------------------------
findroot (BE_snv_125,0,a)
 Filesystem type is zfs, partition type 0x82
bootfs rpool/ROOT/opensolaris-1
kernel$ /boot/$ISADIR/xen.gz
loading '/boot/$ISADIR/xen.gz' ...

Error 15: File not found

Press any key to continue...
---------------------------------

If you perform incremental builds, then this will introduce
some build noise similar to:

==== cpio archives build errors (non-DEBUG) ====

with similar errors about packaging. To workaround, either
remove these files from your proto area, or run a full clobber
build.

        cheers,
                        tim
