Hi,
I started to experiment with xen, so I am still new to it. I was impressed 
how easy I got my first virtual node up and running. 
I measured the disk speed, created a 1gb file with dd. 
copying that file on the dom0 always took about 5 seconds, on the domU, it 
took about 15-20seconds. I used "time cp large_file large_file2" to measure 
the speed. I only expected a small time difference, but not factor 3-4.
My virtual disk is a physical device, configured like this:
disk=[ 'phy:/dev/sdv2,xvda,w', ]
As far as I know, using the physical partitions as the virtual disk, should 
be the fastest solution for virtual disks, compared to files.
Are there different ways to present a physical partition from dom0 to a 
domU, that would influence the speed? Or is the speed factor I have seen 
above the one to expect?
I am on sles10sp1 x86_64.
kind regards
Sebastian
