Description
QEMU: i386: multiboot OOB access while loading kernel image.
QEMU: cirrus: OOB access when updating VGA display.
In certain Red Hat Virtualization (RHV) guest configurations, virtual pass-through devices could not be removed properly. A reference count leak in the QEMU emulator has been removed, and the affected devices are now removed reliably. (BZ#1555213).
Previously, a raw disk image that was using the '--preallocation=full' option in some cases could not be resized. This problem has been fixed and no longer occurs. (BZ#1566587).
Due to race conditions in the virtio-blk and virtio-scsi services, the QEMU emulator sometimes terminated unexpectedly when shutting down. The race conditions have been removed, and QEMU now exits gracefully. (BZ#1566586).
Prior to this update, deleting guest snapshots using the RHV GUI in some cases failed due to an incorrect image-seeking algorithm. This update fixes the underlying code, and guest snapshots in RHV can now be deleted successfully. (BZ#1566369).
