When running virsh snapshot-* command, such as snapshot-create-as / snapshot-delete, it prints a result message. On the other hand virsh snapshot-revert command doesn't print a result message.

So, This patch fixes to add message when running virsh snapshot-revert command. --- # virsh snapshot-create-as vm1 test1 Domain snapshot test01 created # virsh snapshot-revert vm1 test1

# virsh snapshot-delete vm1 test1 Domain snapshot test01 deleted

The full context above: result = virDomainRevertToSnapshot(snapshot, flags); if (result < 0 && force && last_error->code == VIR_ERR_SNAPSHOT_REVERT_RISKY) { flags |= VIR_DOMAIN_SNAPSHOT_REVERT_FORCE; vshResetLibvirtError(); result = virDomainRevertToSnapshot(snapshot, flags); } return result >= 0;

Here you call virDomainRevertToSnapshot again. That makes no sense as the call to revert the snapshot was already done. Additionally the logic above is required to handle the --force flag properly. You must make the decision based on the 'result' variable, not an additional call to virDomainRevertToSnapshot.

Please separate the function name change to a separate commit as it doesn't relate to what this commit is doing.
