Subject Re: Migration among hypervisors
Date Tue, 20 Oct 2015 19:41:55 GMT
I have successfully moved a bunch of vms from xenserver to kvm without any issues. The only
thing that i had to change was the fstab entries where I have not used UUIDs. From what i
recall i had /dev/xvdX device naming in the xenserver and /dev/vdaX in kvm.

Hi Mario, 

you might also want to look at some of the other vendor converters - 
depending on which HV you are converting to: 

Nux¹ comments still stand though - whatever migration method you use you 
will have to sort HV specific drivers and tools as part of the conversion 
- which sometimes involve some surgery.
