RHBA-2012:1322 - Bug Fix Advisory

Topic

An updated ovirt-node package that fixes various bugs is now available.

Description

The ovirt-node package provides the utilities and recipes used to create and
configure the Red Hat Enterprise Virtualization Hypervisor ISO image.

Note: Red Hat Enterprise Virtualization Hypervisor is only available for
the Intel 64 and AMD64 architectures with virtualization extensions.

This updated ovirt-node package fixes these bugs:

• Previously, changing the network configuration of the Hypervisor while

netconsole was enabled resulted in a kernel panic ("Kernel panic - not
syncing: Watchdog detected hard LOCKUP"). This kernel bug has now been
fixed. The Hypervisor has been updated to include a later kernel release
that does not have this bug. Changing the network configuration of the
Hypervisor with netconsole enabled will not result in a kernel panic
(BZ#846431).

• In some circumstances Hypervisor installation previously failed to

create all required sub-directories of the '/var/log/' directory. Attempts
to register such an installation to the Manager would fail because the
'/var/log/vdsm-reg/' directory did not exist. The Hypervisor has been
updated to ensure that all required sub-directories of the '/var/log/'
directory are always created during installation (BZ#855390).

Users of the Red Hat Enterprise Virtualization Hypervisor are advised to upgrade
to this updated package, which corrects these issues and adds these
enhancements.
