Does anyone know how significant the performance hit is when using a partition image file for the file system of a domU instance as opposed to using a file system on a separate disk?
For example:
disk =['tap:aio:/xen/images/mydomU_partition.img,xvda1,w']
vs
disk =['phy:hda1,xvda1,w']
I realize the second config would be faster, but will the first one work pretty well? Does anyone know of any performance papers written on this subject?
Cheers,
Kevin
