Topic
Updated vdsm22 packages that fix multiple bugs are now available for Red Hat
Enterprise Linux 5.5.
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.
Note: This update has been tested and is supported on Red Hat Enterprise Linux
5.5 (with all appropriate post-GA 5.5-specific updates).
These updated vdsm22 packages provide fixes for the following bugs:
- When deleting a virtual guest from an export domain immediately after
re-exporting it, a race condition would cause the export to be issued before the
delete finished and the operation would fail. With this update, this and similar
race conditions no longer cause a failure. (BZ#609148)
- Previously, when creating a new domain, an existing physical volume (PV) was
referenced in the GUI by its UUID. With this update, the GUI displays the LUN
(Logical Unit Number) serial number and the vendor number. (BZ#609424)
- Occasionally, executing the 'lvs' command would not return tag metadata for a
volume which caused certain operations to fail. With this update, the 'lvs'
command retries this process until the metadata is returned. (BZ#616417)
- When VDSM was restarted on a loaded server with multiple virtual guests
running, it occasionally failed to connect the guest socket of a virtual guest,
analyzed that as an error of the virtual guest, and destroyed the virtual guest.
With this update, VDSM connects to the guest socket on a different thread, with
no delay to VDSM recovery, and without destroying any virtual guests.
(BZ#617108)
- An arbitrary limitation prevented attaching more than 8 NFS storage domains to
a pool. With this update, the limitation is removed. (BZ#622438)
- On a host with dozens of CPUs, VDSM allowed multiple concurrent migrations,
which negatively affected the network connectivity and caused the operations to
time out before their successful termination. With this update, VDSM limits the
number of virtual guests being migrated at the same time to a configured value
(5 by default). Concurrent migration of dozens of virtual guests is serialized
and finishes successfully. (BZ#623713)
- On a host that holds both, FC (Fibre Channel) and iscsi devices, the
connectStoragePool function failed with a "Cannot find master domain" exception
if it was not possible to re-scan one of the devices in
/sys/class/scsi_host/hostX/scan. With this update, this failure no longer
occurs. (BZ#628290)
- When trying to delete an image, VDSM uses the deleteImage task synchronously
which resulted in unwanted behavior in the Red Hat Enterprise Virtualization
Manager task manager. With this update, this task is done asynchronously and the
Red Hat Enterprise Virtualization Manager task manager works as expected.
(BZ#628449)
- Due to incorrect filtering of restricted characters in XML-RPC responses,
certain messages from the virtual guest could cause all virtual guests on the
same host to become unresponsive. With this update, forbidden characters in the
XML-RPC responses no longer affect the virtual guests. This complements a
previous fix of BZ#606281. (BZ#630753)
Red Hat Enterprise Virtualization Manager 2.2 users with Red Hat Enterprise
Linux hosts should install these updated packages, which resolve these issues.
Alternatively, Red Hat Enterprise Virtualization Manager can install the new
package automatically.
