RHBA-2014:0219 - Bug Fix Advisory

Topic

Updated vdsm packages that fix a bug 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.

Changes to the ovirt-engine-backend component:

• Previously, VDSM's documented port range for SPICE was 5634 to 6166, but it

used libvirt's default range of 5900 to 65535. Consequently, firewalls set
according to this range could erroneously block SPICE traffic. Now, VDSM uses
the 5900 to 6923 range for SPICE, which allows concurrent running of up to 512
virtual machines using the SPICE console. (BZ#1052162)

Changes to the vdsm component:

• vdsmd now starts on the first run, even if no VDSM logs are present in the

RPM. (BZ#1065972)

• The iscsi daemon is now started when VDSM starts, and iSCSI storage is now

available when VDSM starts. (BZ#1058785)

• vdsm-python-cpopen is no longer installed. (BZ#1063180)
• sosreports no longer contain entire block devices, and this means that the

size of sosreports is now much smaller. (BZ#1062964)

• Virtual machines are no longer paused after migrations; hosts now correctly

acquire resource locks for recently migrated virtual machines. (BZ#1059129)

• An update to VDSM adjusts the libvirt XML to match the form the destination is

using after a migration from an older version of RHEV-H to a newer version of
RHEV-H.
Logs are no longer flooded with messages about invalid paths. (BZ#1065902)

• VDSM now provides before and after setup network hooks. (BZ#1058707)
• ifcfg files for physical interfaces no longer include HWADDR lines that

specify MAC addresses. (BZ#1058705)

• Bond speeds are now reported accurately. (BZ#1037557)
• before_device_migrate_source is now called by VDSM as expected. (BZ#1055518)
• getVdsCaps now reports the correct last client IP and lastClientIFace, which

allows the management bridge to be correctly installed. (BZ#1055557)

• TBA (BZ#1061642)
• after_update_device now runs as expected after a hook fails to run.

(BZ#1055656)

• The correct version of qemu-img-rhev is now listed correctly in VDSM's

dependencies. (BZ#1055516)

• RHEVM now recognizes preconfigured networks in which the management network is

bridgeless and untagged, making it unnecessary to drag and drop these networks
to the bond interface in order to recognize them. (BZ#1044024)

• When VDSM fails to create a snapshot, VDSM receives a request from the engine

to perform a rollback and start a deleteImage task. Previously, the deleteImage
task was stuck forever on VDSM, and had to be manually removed by the user. The
deleteImage task is now properly executed. (BZ#1056598)

All users managing Red Hat Enterprise Linux Virtualization hosts using Red Hat
Enterprise Virtualization Manager are advised to install these updated packages,
which fixes this issue.

These updated packages will be provided to users of Red Hat Enterprise
Virtualization Hypervisor in the next rhev-hypervisor6 errata package.
