Fixed In Version: mingw-virt-viewer-2.0-1.el7ev
Doc Type: Bug Fix
Doc Text:
Previously, the SPICE client did not send a data message when transferring zero-sized files by drag and drop. Because the guest agent expects to receive a message, it would keep a file open, causing a leak. This has been fixed by adding a transfer message for zero-sized files to prevent guests from leaking file descriptors in the guest agent during the copy.
