Hello world,
I used to use Xen on my server but due to a non-patched cygwin problem
I installed kvm 83 on my redhat 5.4 with the red hat rpm.
I found some troubles with a windows 2008 server 64 bits guest. When I
install a software like an anti-virus it takes a lot of time compare
to Xen ( that takes 10 times more time on kvm) .
The guest task manager displays 100% of the cpu is used but with the
virt-manager (host) I can see just 7.5% of the cpu is used. Do you
have any solutions ?
As regards, thanks in advance

It's probably disk activity. Can you verify with vmstat?
If so, try using an lvm volume instead of a qcow2 file.
