Only today.. manage to reach 26x CPU load..
freaking-load-average
with..

xen running to install windows xp on CentOS 5.2
firefox..
vncserver
squid..
nagios
zm ..

apparently .. the load decrease significantly when
killing firefox..

then .. start killing nagios.. also vncserver.. and virt-manager console..

as figured out how to connect direct to the guest after that..
then only it was a bit “Okay”
