 In the past, I know better than to have attempted this.. but in recent 
explorations, I seem to have read somewhere that there's a kernel option 
to output to serial port, and that the xm console for an HVM would in 
fact be the serial port output?
 Or did I misinterpret this?

 I would if I were on the machine in question. As it is, it is at a 
remote location and I'm accessing it over a VPN... so unless I'm missing 
something (ie can I even use the SDL way if I'm NOT on the local 
machine's console??) I can't go this route.

 Is it essential to add the "bridge=xenbr0" ?

 Will networking not work in an HVM without it?

 And.. with all the recent talk about bridging and Xen 3.2, I get the 
impression xenbr0 isn't used in the same capacity anymore... in which 
case, should I say "bridge=eth0" ? Or, is that referring to something 
else entirely?

 Out of the 30+ times I attempted to boot my HVM, maybe about 4-5 times 
did I actually/eventually see anything.. maybe a HVM POST screen (ie VGA 
BIOS, disk controller being "detected" etc.) or the initial debian text 
mode installer screen.
 I'm assuming when you say "text mode install" you mean non-X... which 
is all I'm shooting for (I'm not doing HVM in this case for X, I'm doing 
it for a fully contained machine that I can run some non-Xen kernels on).
 Thank you for your thoughts. I will keep plugging away with them in mind.
