Virtual disks in Xen: per file per partition or per file per disk?

Question

Xen

Colleagues, good day.
I noticed that in Xen you can configure guest disks in two ways:

1. disk = ['file:/xen/disk.img,sda,w']

   (and in the guest disk this disk is divided, for example, into 3 partitions)
   

2. disk = ['file:/xen/firstpart.img,sda1,w','file:/xen/secondpart.img,sda2,w', 'file:/xen/thirdpart.img,sda3,w']

   
   

Has anyone studied the data, which of these options is more productive? I suspect that the second ... But are there any links on the topic? Thank you.

Answer 1

the question is a bit off topic: why are you not satisfied with LVM volume groups?
