Issue with Ubuntu and Xen-3.3.2
The Dom0 is a NetBSD-5.2/amd64 installation running Xen-3.3.2, with a
number of DomU's, mostly NetbSD-5, but we've run Linux CenTOS in the past
on this setup.
hello. Ok, I realize I'm running an ancient version of Xen, but it's
a production environment and it's been very stable for us. Now, I'd like
to bring up a Ubuntu domU and I have it almost working.
I'm using ubuntu 16.04 with a 4.4.0-51 Linux kernel. I'm trying to bring
up the installation environment and I'm getting stuck after the kernel
loads, but before the userland processes begin. I get further if I define
more than one vcpu, but the VM still crashes.
I've also tried bringing up an HVM, but I couldn't figure out how to
get the ISO image to use a serial console. I'm sure there are more ways to
poke at this problem, but if anyone has ideas on what I might try to either
solve the issue or get more information about the nature of the problem,
I'd be very appreciative.
My config and boot messages are below.
-thanks
