Bug Description

When using an older microversion (2.25 or earlier) with boot-from-image, and the user forgets to specify block-migration, the error message returned is this:

"Live migration can not be used without shared storage except a booted from volume VM which does not have a local disk."

This has a couple things wrong with it. First, the triple-negative is a bit confusing, especially for non-native-english speakers. Second, it implies that you cannot do a block migration, which is obviously false.

I think a more clear error message would be something like:

"Shared storage migration requires either shared storage or boot-from-volume with no local disks."

    fix InvalidSharedStorage exception message

    The exception message for InvalidSharedStorage is grammatically
    complex and ignores the possibility of block migration, which
    results in a misleading and confusing message for the user.

    Change it to something simpler and more accurate.
