Hi all,
i have a question. I'm going to setup a Xen server for a client.
It's going to serve about 25 clients.
It's a Athlon 64 3200+, which currently runs Debian i386-stable and xen
2.0.7
until Xen 3.0 is stable enough, and then i'm gonna replace it with
Debian amd64-stable and Xen 3.0.
The Xen dom's consists of:
Samba , file printer sharing most active all 25 users all the time
network io is a lot.
Mail 25 users, + webmail + clamav + spamassassin + amavis
Proxy squid + squidguard + willowbark (uvscan, which cooperates with
the www
who does the actual scanning)
WWW www server for about 25 concurrent users, who access the some of the
samba files. Not very IO heavy but some disk IO is involved.

Full spec's at bottom:
The server is a (overkill but it's going to last at least 5 to 7 years) :
AMD athlon 64 3200+
2 G internal DDR 400 Mhz
Sata drive (hdparm -Tt gives 1549/65.33 mb/sec)
radeon 9600 don't know how much mem, but who care's it won't be running X
Marvell Yukon Gigabit Lan onboard.
How should i divide the memory for the dom's , what about swap?
i was thinking:
DOM MEM SWAP
dom0 512 750
samba 768 250
www 256 100
proxy 256 100
mail 256 100
Any other suggestions are welcome....
any other info needed?
any tuning tips?
kind regards and thanks in advcance.
