Re: Xen 3.x with NetBSD 3.x x86-64/64-bits/amd64 Dom0

This is disappointing news.
If I want to run Xen on an old Pentium 3 733Mhz with 512M
RAM am I 
better off to run Xen2 with NetBSD Dom0 or Xen3 with a Linux
Dom0 ?
The virtual machines will be home mail server, web server,
file server 
with little load on them.

thanks, Philip

1.) NetBSD 3.x can *not* be used a Xen 3 dom0. NetBSD 3.1
can be used as
    a Xen 3 domU, all other releases of NetBSD 3.x only
support Xen 2.
2.) NetBSD doesn't support Xen for AMD64.
3.) Xen for AMD64 seems to have a lot of issues in general.

The good news is that NetBSD 4.0_BETA2 support running as
Xen3 dom0.

512MB is not much in Xen land.

You could try NetBSD 4.0_BETA2 as Xen3 Dom0 and NetBSD 3.1
as Xen3 domU.

Virtual machine*s*? Running several virtual machines in
512MB won't
allow you to use much memory per domU which could lead to
poor
performance.

thanks.  i will look at netbsd 4
my web server is running as cooperative linux vm on top of
XP with 64M 
RAM at the moment, and it seems quite happy.  Linux and BSD
don't need 
much RAM provided that no x server is running
anyway the point is to play with it more than anything else

regards, Philip

I recommend xen2/NetBSD  -  looking at my uptime numbers, it
is quite 
superior if you can get by without xen3 features.
