Thanks to all the help, I’ve gotten most of this to work for both Debian and LinuxMint; I’ll  summarize once complete for the record.

What has worked: booting install images, connecting via vnc, installing the OS on a second disk image, booting the second image.  For Debian, all this works, and the second disk can be run as a PVH DomU.  For LinuxMint, all this works for HVM DomUs only.

I have tried more or less the same configuration for the LinuxMint PV DomU as for the working Debian PV DomU:

kernel='/xen/linuxmint-21.1-cinnamon-64bit-vmlinuz-5.15.0-56-generic'
ramdisk='/xen/linuxmint-21.1-cinnamon-64bit-initrd.img-5.15.0-56-generic'
type='pvh'
memory = 2048
cpu_weight = 64
name = "linuxmint-pv"
vif = [ 'mac=aa:00:00:d1:00:09,bridge=bridge0' ]
disk = [ 'file:/xen/linuxmint-21.1-cinnamon-64bit.img,ioemu:hda,w', ]
root = "/dev/xvda1"
vga = 'stdvga'
videoram = '16'
vfb = [ 'type=vnc,vnclisten=127.0.0.1’ ]

This reports in the vnc window “This VM has no graphic display device.”  That message occurs with or without the vga+videoram statements and with or without the vfb statement.

Any ideas?

Thanks again for all the help.

Cheers,
Brook
