pvshim for 32-bit PV guests - what am I doing wrong?

[Andy Smith <andy@xxxxxxxxxxxxxx>]

Hi,

Let's say I have a 32-bit PV guest being booted with pvgrub2 like
so:

name   = "tracker0"
memory = 1024
vcpus  = 2
cpus   = "all,^0,^1"
vif    = [ "mac=00:16:5e:00:01:f5, ip=192.168.80.250, vifname=v-tracker0" ]
type   = "pv"
kernel = "/opt/grub/lib/grub-i386-xen.bin"
disk   = [ "phy:/dev/xenvg/domu_tracker0_xvda,xvda,w" ]

So if I want to run it under pvshim, I should change the config to this, right?

name   = "tracker0"
memory = 1024
vcpus  = 2
cpus   = "all,^0,^1"
vif    = [ "mac=00:16:5e:00:01:f5, ip=192.168.80.250, vifname=v-tracker0" ]
type   = "pvh"
pvshim = 1
kernel = "/opt/grub/lib/grub-i386-xen.bin"
disk   = [ "phy:/dev/xenvg/domu_tracker0_xvda,xvda,w" ]

But when I try to create that guest, I just get this:

$ sudo xl -v create -c /etc/xen/tracker0.conf

What am I doing wrong?

This is Xen 4.12.4.

Thanks,
