I agree that virtualising FreeBSD is useful but I suspect your chances of getting guest patches for FreeBSD 4.x are very low. FreeBSD 4.x is no longer supported by the FreeBSD project and there are significant changes in the kernel architecture between 4.x and later versions. For new features to be added to FreeBSD, they must be first added to the latest version and then back-ported to older versions - the backport to 4.x would probably require significant effort. >KVM has now special drivers, based on the virtio specifications.

I think that they are pretty simple in the guest side (75kb of >code for linux for example, for network and block device) but I'm not >very good in kernel driver compilation. Note that FreeBSD does not have block-mode devices. --=20 Peter Jeremy Please excuse any delays as the result of my ISP's inability to implement an MTA that is either RFC2821-compliant or matches their claimed behaviour. --7uYPyRQQ5N0D02nI Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) iEYEARECAAYFAkhJqJ4ACgkQ/opHv/APuId+MgCglHA6MO6Al2mddepu7wrhKkIL 5gUAn3D6Vg9KnyGffQz/ByGWr7FMYi8y =kLEX -----END PGP SIGNATURE----- --7uYPyRQQ5N0D02nI--
