and the VM now boots. Many thanks.

I note from the best practices doc that "Because qemu-system-x86_64 usually
also provides better performance for 32-bit guests, SUSE generally recommends
using qemu-system-x86_64". I appear to be using qemu-system-i386 but I couldn't
find out how to change it ...
