Just a couple of quick questions that were running around in my head
lately. First, can either of the bsd ports operate as privleged domains
yet? And second, is it currently possible to do something like the following:
hard disk(s) nic(s)
| |
| |
/-----------\ /-----------\
| dom0-priv | blk dev | dom1-priv |
| |--------------| |
| xend | event chnl | |
\-----------/ \-----------/
and then have xend create unprivleged domains with block device event
channels hooked up to domain 0, and network device event channels
hooked up to domain 1?

Which two are you referring to?

Xend configuration files should allow you to specify what domain to use as a backend for a device. I''m not sure anybody has actually ever tried it...

(also there are more than 3 BSDs...)> > "First, can any of the bsd ports operate as privleged domains yet?"The NetBSD port to Xen 1.2 is complete and works as a privileged domain -- you can run a Xen 1.2 NetBSD only machine. There''s currently no incentive to make the port to Xen 2.0 operate as a privileged domain. christian ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.

Ports of FreeBSD and Plan 9 are nearing completion. j. ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
