For now, I’m just trying to get something to work.

This is helpful as it seems to make a bit of progress.

I downloaded a Debian image and tried to create a Xen instance with the following conf file modeled after yours:

kernel = "/usr/pkg/lib/xen/boot/hvmloader"
builder='hvm'
device_model_version="qemu-xen-traditional"
memory = 2048
cpu_weight = 64
name = "debian"
vif = [ 'mac=aa:00:00:d1:00:09,bridge=bridge0' ]
disk = [ 'file:/path/to/xen/debian-live-11.6.0-amd64-cinnamon.iso,hda,w', ]
boot='c'
vfb = [ 'type=vnc,vnclisten=X.X.X.X' ]

I get the following message:

	WARNING: you seem to be using "kernel" directive to override HVM guest firmware. Ignore that. Use "firmware_override" instead if you really want a non-default firmware

Is this something to worry about?

More importantly, I am not able to connect to the running instance.  Connecting with “xl console” just hangs.  Perhaps vnc should work, but I’m not sure how to do that.  I have tried vncviewer commands that are analogous to what I use for other systems, but nothing connects, despite trying several different IP addresses for the vfb.  Do I also need to define a display?

I’m not sure how to see what is actually running.  Does anyone have a known-good image and conf file to share (off list).

Any suggestions welcome.

Thanks a lot.

Cheers,
Brook
