mbraligned linux vms result in Partition 1 not ending on cylinder boundary

From what I understand, running mbralign shifts all the data to new fs boundaries, so seeing this warning/error when looking at the output of a 'fdisk -l' almost seems expected.  My test VM is still able to boot normally with this error, but I was wondering if anyone else has seen this and had negative impacts to their VM?

Thanks

Screenshot by any chance? Or the output from "mount"? (am curious about the file system in question)

It's an ext3 filesystem

eleenchiang,

Your inclination was correct.  The cylinder boundary warning isn't valid for virtual disks (or virtual luns).  There is/was a advantage to taking cylinder and track boundaries into consideration when the geometry described a physical disk, but there is none in this case.
Hope this helps.

Thanks forgette for the reassurance.  I will boldly move forward and align all of my linux vms without as much concern now.
