RHBA-2015:2202 - Bug Fix Advisory

Topic

Updated libvirt packages that fix several bugs and add various enhancements are now available for Red Hat Enterprise Linux 7.

Description

The libvirt library is a C API for managing and interacting with the virtualization capabilities of Linux and other operating systems. In addition, libvirt provides tools for remote management of virtualized systems.

The libvirt packages have been upgraded to upstream version 1.2.17, which provides a number of bug fixes and enhancements over the previous version. (BZ#1194593)

This update also fixes the following bugs:

• Previously, when the default CPU mask was specified while using Non-Uniform Memory Access (NUMA) pinning, virtual CPUs (vCPUs) could not be pinned to physical CPUs that were not contained in the default node mask. With this update, the control groups (cgroups) code correctly attaches only vCPU threads instead of the entire domain group, and using NUMA pinning with the default cpuset subsystem now works as expected. (BZ#1207257)
• After hot-plugging an invalid LUN device, the next start or reboot of the guest failed, and the guest could not be started until the hot-plugged device was removed. This update adds an additional domain XML check that properly detects invalid LUN devices, and attempting to hot-plug them now fails. (BZ#1201143)
• Previously, attempting to use the virDomainGetBlockIoTune() API failed on systems running a recent version of libvirt together with an earlier version of QEMU. With this update, libvirt correctly checks QEMU version compatibility, which makes it possible to use the virDomainGetBlockIoTune() API even with less recent QEMU versions. (BZ#1224053)
• The severity of the "VIR_ERR_NO_DOMAIN_METADATA" error has been lowered to the DEBUG level, which ensures that the error no longer clutters libvirt logs. (BZ#1220474)
• Previously, the libvirtd daemon terminated unexpectedly when parsing disk volume backing strings that contained a URI without a path. With this update, libvirtd has been adjusted not to access the path segment of a URI when the path is not provided, and the described crash no longer occurs. (BZ#1189007)
• If a running guest was pinned to a host NUMA node, moving the guest to another node failed. With this update, libvirt primarily uses cgroups to configure host NUMA node affinity, and moving a running pinned guest works. (BZ#1206625)

In addition, this update adds the following enhancements:

• A number of new options have been added to the "virsh blkdeviotune" command that allows the user to configure for block device I/O throttling. For more information, see the virsh(1) man page. (BZ#1157997)
• With this update, libvirt supports the memory hot-plug and hot-unplug features, which allow users to dynamically re-allocate memory resources among virtual machines. (BZ#790583)
• The virDomainSetUserPassword API has been introduced in libvirt. This allows setting passwords for any guest user, including the administrator, by using the QEMU guest agent. (BZ#1174177)
• It is now possible to disable "mrg_rxbuf" for virtio network interface controller (NICs) in the domain XML file. This allows the use of applications that cannot run with "mrg_rxbuf" enabled. (BZ#1186886)
• This update enables support for the Ceph storage driver backend, and thus allows Ceph storage pools to be accessed via libvirt APIs. (BZ#1187533)
• When performing a live migration on a domain including its disks, libvirt now automatically pre-creates storage on the destination file system. This simplifies the migration process and prevents potential errors caused by pre-creating storage manually. (BZ#927252)
• When live migrating a domain as well as its disks, the user can now select which disks are copied during the migration. (BZ#1210352)

Users of libvirt are advised to upgrade to these updated packages, which fix these bugs and add these enhancements. After installing the updated packages, libvirtd will be restarted automatically.

Solution
