RHBA-2015:2234 - Bug Fix Advisory

Topic

Updated hyperv-daemons packages that fix two bugs are now available for Red Hat Enterprise Linux 7.

Description

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

This update fixes the following bugs:

• Using the online backup feature on read-only file systems that do not support system freezing, for example SquashFS, failed with an "Operation not supported" error. This update fixes the hypervvssd daemon to handle the online backup correctly, and the described error no longer occurs. (BZ#1160584)
• Previously, on a virtual machine managed by the Microsoft Hyper-V hypervisor, the hypervvssd daemon did not detect partitions that were mounted more than once, for example when a partition was mounted simultaneously to several different mount points. Consequently, the Windows Backup tool failed to back up the data of such virtual machines. With this update, the hypervvssd daemon has been fixed to detect partitions even if they were mounted more than once. As a result, using the Windows Backup tool on machines with such configuration now succeeds. (BZ#1169724)

Users of hyperv-daemons are advised to upgrade to these updated packages, which fix these bugs.
