When started with other accelerator than Xen, the XenPV machine
fails with a criptic message:
$ qemu-system-x86_64 -M xenpv,accel=kvm
xen be core: can't connect to xenstored
qemu-system-x86_64: xen_init_pv: xen backend core setup failed
By restricting it to Xen, we display a clearer error message:
$ qemu-system-x86_64 -M xenpv,accel=kvm
qemu-system-x86_64: invalid accelerator 'kvm' for machine xenpv
