QEMU doesn't start with "qemu-system-i386: -xen-domid 1: Option not
supported for this target"

This happens if CONFIG_XEN isn't set.

QEMU is built with:
                  host CPU: aarch64
           host endianness: little
               target list: i386-softmmu

commit 8a19980e3fc4 "configure: move accelerator logic to meson"
introduced this logic:
+accelerator_targets = { 'CONFIG_KVM': kvm_targets }
+if cpu in ['x86', 'x86_64']
+  accelerator_targets += {
+    'CONFIG_HAX': ['i386-softmmu', 'x86_64-softmmu'],
+    'CONFIG_XEN': ['i386-softmmu', 'x86_64-softmmu'],
+    'CONFIG_HVF': ['x86_64-softmmu'],
+    'CONFIG_WHPX': ['i386-softmmu', 'x86_64-softmmu'],
+  }
+endif

I guess something like this would fix it:
if cpu in ['aarch64', 'arm']
  accelerator_targets += { 'CONFIG_XEN': ['i386-softmmu'], }
endif

I don't have an arm setup to test this.

2020-10-27 14:08:29 Z lvdisplay output says device is still open:
/dev/fiano1-vg/test-amd64-amd64-xl-qcow2_debian.buster.guest.osstest-disk:fiano1-vg:3:1:-1:1:20504576:2503:-1:0:-1:253:2

It's unclear to me why the disk is still in use.  Looks like QEMU exited.
