Thanks.  I've read MRJ's blog at various points along my journey...

What's SXCE?

Oh yeah... :)

I've had several different problems at various stages.  For example,
using Nevada build 87 and Xen 3.2.0, I was able to get the install CD to
boot and install the system, but it would kernel panic when booting into
the installed OS.  Looking for the cause, I found some indication that
my trouble might be fixed by an upgrade, but since moving to Xen 3.2.1
and OS2008/05, I can't get the install CD to boot.

Yes, it's based on Nevada build 86 . You are supposed to failure.
John Levon's patch went into build 87.

Okay, my Solaris kernel command line mojo is pretty weak... I changed my
"extra" line to read:

  extra = '/platform/i86xpv/kernel/amd64/unix -kd'

Was that right, or should I have left the "-B
console=ttya,livemode=text" parts in place?  At any rate, when I try to
boot with that I do get into the debugger.  Typing "::stack" returns:

  kmdb_enter+0xb()
  mlsetup+0x35c(fffffffffbc6ee28)
  _locore_start+0x7b()

Does that tell you anything?

> Also which builds of SXCE did you try?

I've only tried Nevada build 87 previous to this.

BTW, I've just logged into the IRC channel and I see you're there too,
would be happy to take this over there if it's easier.

Thanks much,
