This article describes the Microsoft System Center Virtual Machine Manager 2008 R2 (SCVMM 2008 R2) Service Pack 1 (SP1) issues that are resolved in the hotfix rollup package that was released on July 12, 2011.
List of issues that are resolved
A Virtual-to-Virtual (V2V) migration to a Cluster Shared Volume (CSV) volume fails if the cluster node that owns the volume has insufficient disk space on the system volume. Additionally, you receive an error that resembles the following:
Unable to perform the job because one or more of the selected objects are locked by another job.
Virtual machine placement may show a host as having a zero rating. If you select the host, the following message is listed on the Rating Explanation tab:
The projected disk i/o utilization (IOPS) 0 exceeds the maximum disk i/o utilization (IOPS) of -1687.
Note This issue occurs if the disk IOPS reservation for the host placement is set to a value that is larger than 2097.
A cluster node might not enter Maintenance mode, and you receive the following error because of a timing issue:
Could not initiate live migration of Virtual machine SCVMM vmname to virtual machine host servername using this cluster configuration.
