Updated hyperv-daemons packages that fix one bug are now available for Red Hat Enterprise Linux 6.
The hyperv-daemons packages provide a suite of daemons that are needed when a Red Hat Enterprise Linux guest is running on Microsoft Hyper-V. The following daemons are included: - hypervkvpd, the guest Hyper-V Key-Value Pair (KVP) daemon - hypervvssd, the implementation of Hyper-V VSS functionality - hypervfcopyd, the implementation of Hyper-V file copy service functionality
When mounting a read-only file system that does not support file system freezing (such as SquashFS) and using the online backup feature, the online backup previously failed with an "Operation not supported" error. This update fixes the hypervvssd daemon so that it handles the online backup correctly, and the described error no longer occurs.
Users of hyperv-daemons are advised to upgrade to these updated packages, which fix this bug.
