Added GPFS as shared file system recognized during live migration
security checks.

GPFS is 'IBM General Parallel File System' also called
'IBM Spectrum Scale'

One thing which might be worth exploring is whether GPFS is also
migratable with cache != none and thus should be also added to
virStorageFileIsClusterFS.

ACK.

Depending on the angle of view this can be viewed both as a bug and as a
feature.

Bug, since we consider this a blocker for migration.

Also, probably a regression introduced by commit ed11e9cd95bd9cae6cdfab14ae0936930bbb63e6
   qemuMigrationSrcIsSafe: Check local storage more thoroughly

Since we are feature freeze, is anybody objecting in pushing
this right away? (obviously I'm not going to push it right now)


I object to calling this a feature. Feel free to postpone if you deem it
too risky or invasive.
