Hi! Thanks for your reply - I should have posted to say I'd partially solved this.

I think the commandline looks much simpler this way. OTOH, I can see that this might help with my next problem, which is that I want to write EGD support for virtio-rng, so I'm guessing my commandline would (in your scheme) need to be something like: -tcpsocketthing $addr.of.egd.server,id=some-name-here, more-egd-client-options -device virtio-rng,tcpsocketthing=some-name-here,rate=$limit I guess the idea here is to seperate the host related config from the guest OS setup ? This doesnt, however, get around my problem that the -device option doesnt know how to parse OPT_SIZE types, though. (I'd like to be able to specify 'rate' in B/s or KB/s (or even kbits/sec, more appropriately)) - -Ian -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQIcBAEBAgAGBQJLAUWCAAoJEFIjE1w7L6YHi7YP/1JXi1T1T3/GUG8o+ZTXJbV5 KUCkwZct7bAqMaZyxsbkbqo947tNjL006kupvUwRsfS/Hrp2uf9K/+o0tTGr87Kl ec7sWAU67q1ydhFQQYcAnUeBEe2qO9qIXC2d32QOPOTBftwmmCYMSRob+VG0jOvy eBN9ZdnUM+vGWmFfAxH8U1Wcx4sxEni+QZ36cFSCwAVfimxqkj9h2sI4yYVmIwWI 3VN6BERQgBGMp81fRY+QiVFGSXEPfLi/ppI8Ta6MOO3dB91XzsqDcMNIHIJwmxFz S2uSMl9py3P5jGb2hhHHO56Fvl8paBOEvVm1SsOMXID9MpnrSHJZmlnKAe+P0nY2 EX+pvvqJZwA2OS15fjzypmho0WZtvS/HdrvEp9SQcM6dgfyVapR6H/GLrqV1iEZ5 uarKBbFKuWVCl8rWc4dZm6sMDfIuzjUgeMZyEhUx3dHVpzzd1B0zIZOVFyI7Fde1 +ox+lvm4EXBV/hji4GCc3E1pJSlmQtokSSTuaVrAXrwJRJcZpX3cjsQad5S5OOrI zXYgs2H/ITINxnVjxkPTHty1txcZrs2Wvjbs8LvkE7LsZuquy+maVN2VS7ahwy3q qCAkfm8Yp1QVmPM1sAlhuMPCrtQKl4VAt825PbpjEd4DNHZb1hnK8s7dc3NpVKcv NK+vr3fUldUlsU+6Om0r =yNv7 -----END PGP SIGNATURE-----
