This is because you're trying to boot Para-virtual Linux on a device
called "/dev/sd0a", which you haven't got according to your "disk=" line
(you have "0x03" and "0x04")... 

But that's got nothing to do with the netbsd, of course. 

Is that a NetBSD install CD? In that case, you'll need to use HVM (full
virtualization), which requires a processor with AMD-V (SVM) to start
off. You also need some modifications to the config file (look at
/etc/xen/xmexample.hvm for a base-config), and you probably want to add
":cdrom" after "0x04" on your disk-line to make QEMU-DM aware of it
being a CDROM rather than a hard-disk.
