info about the system specifications via hdparm

http://gentoo-wiki.com/HOWTO_Use_hdparm_to_improve_IDE_device_performance
hdparm -I /dev/sda

aptitude did not work, after asking there seems to be some problems

with the apt-cache server which crashes sometimes and
belnet does not work properly these days.
Changed sources.list with new mirrors: uk.debian.org now it works
REMARK: for apt and wget no proxy is neccessary because of the apt proxy. For debootstrap a proxy is neccesarry

system specs are the same on both machines
hdparm -tT /dev/sda does gives some benchmark information about the disks
tried to install apache2 on xen domU

networking does not work properly

eth0: ERROR while getting interface flags: No such device
SIOCSIFADDR: No such device
eth0: ERROR while getting interface flags: No such device
SIOCSIFNETMASK: No such device
SIOCSIFBRDADDR: No such device
eth0: ERROR while getting interface flags: No such device
eth0: ERROR while getting interface flags: No such device
Failed to bring up eth0.

in the /xen/xentest.cfg there was no vif = "bridge=xenbr0"
added this in the config file
restart xend now ifconfig gives all the interfaces
http://wiki.xensource.com/xenwiki/XenNetworking -- info on the interfaces
now xm create an xm console
in the domU ifconfig gives the correct data
http://www1.shorewall.net/XenMyWay.html
I can ping the dom0 but not the 10.10.3.165 machine
But from the .165 machine I can ping the .163 machine
aptitude now works if I use the export proxy thing

Starting with some benchmark testing

wget http://www.tux.org/pub/tux/benchmarks/System/unixbench/unixbench-4.1.0.tgz
install make and gcc for this
cd into dir en do a make
./Run
tried it on the ubuntu domU --> Does not work very well
On debian dom0 it works fine
