Some of you on the list are aware of a VM image with scripting
specifically to support the oddities of netbooting/installing classic
SGI systems. DINA (http://dina.harrydebug.org, will deregister at end of
May but I've mirrored it) has some rough edges I've been meaning to go
back and fix, but is a lifesaver compared to CD installs. The original
DINA image is VMware flavored, but I've gotten it running under
VirtualBox and I think others have done the same for one or two other
platforms. More info about DINA is available here:
DINA can't include the IRIX software, though that's all a user has to
add. But VM images setup to serve various architectures of free
operating systems (Linux, *BSD) certainly could. How about a
netboot/install server for NetBSD that included VAX, SPARC, MIPSco, x86,
etc? Maybe, like DINA, it's already out there and it just hasn't been
publicized outside of a given circle. Heck, maybe I'm the only one
unaware of it. ;)
Including a runtime environment for IRIX or SunOS within the VM...
interesting. Distribution of a VM image including the software would
again be "problematic" - at least from a copyright/IP perspective. But
technically I don't see why you couldn't serve a SunOS 4 runtime
environment from an x86 *BSD VM, for example.

I'd be thinking of netboot/install server images as separate from
emulators intended for end-users to fiddle with. Maybe that's just an
old sysadmin reflexively wanting to keep the regular users away from
where the infrastructure services are running...
