RHBA-2015:1729 - Bug Fix Advisory

Topic

Updated vdsm packages that fix several bugs and add various enhancements are now
available.

Description

VDSM is a management module that serves as a Red Hat Enterprise Virtualization
Manager agent on Red Hat Enterprise Virtualization Hypervisor or Red Hat
Enterprise Linux hosts.

Bug fixes and enhancements with this update include:

Changes to the ovirt-hosted-engine-setup component:

• On Red Hat Enterprise Virtualization Hypervisors, the vdsmd and libvirtd

services experienced restart errors while deploying the Self-Hosted Engine. The
hosted-engine setup script changes the VDSM configuration file and restarts it,
but this is not enough; explicitly calling vdsm-tool configure is also required
to make the changes effective and void any race condition on the services'
start-up. (BZ#1235591)

Changes to the vdsm component:

• Due to a bug in VDSM, ifcfg files that served multiple networks sometimes

contained ONBOOT=no, and as a consequence, rendered management networks (or
other important networks) unavailable during the early stages of boot. As a part
of another change, all ifcfg files are now ONBOOT=yes, thus solving this bug,
and making this scenario impossible. All networks are now loaded by network
service and are not flushed later by VDSM, except in cases where the VDSM
service recognizes them as different from the persistent network configuration.
(BZ#1242508)

• This release defers the ability to use VDSM in cluster versions 3.0 to 3.3.

Over el6, vdsm-3.5 supports all clusters and Managers from 3.0 to 3.5. Over el7
and Fedora, VDSM stops supporting clusters below 3.4 and Managers below 3.3.
Support for 3.4 Managers stays as tech-preview over el7. (BZ#1234320)

• When working with Red Hat Enterprise Linux 7 hosts, the power management

boolean options (true/false options) should have an explicit value (i.e. value=0
or value=1). In the past it was enough to pass "value" when referring to
"value=1". This fix changes that in the database for all known boolean values,
except for cases in which the options are encrypted. If your environment has
encryption enabled for these options, then you have to manually change the host
power management options for Red Hat Enterprise Linux 7 hosts. (BZ#1225082)
