Introduction

This article describes the issues that are fixed in Update Rollup 8 (UR8) for Microsoft System Center 2012 R2 Virtual Machine Manager. There are two updates available for System Center 2012 R2 Virtual Machine Manager: one for servers and one for the Administrator Console. This article also contains the installation instructions for Update Rollup 8 for System Center 2012 R2 Virtual Machine Manager.

Features that are added in this update rollup

  • Support for SQL Server 2014 SP1 as VMM database
    With Update Rollup 8 for SC VMM 2012 R2 you can now have Microsoft SQL Server 2014 SP1 as the VMM database. This support does not include deploying service templates by using the SQL profile type as SQL Server 2014 SP1. For the latest information about SQL Server requirements for System Center 2012 R2, see the reference here.
  • Support for VMWare vCenter 6.0 management scenarios
    With Update Rollup 7, we announced support for management scenarios for vCenter 5.5. Building on our roadmap for vCenter and VMM integration and supportability, we are now excited to announce support for VMWare vCenter 6.0 in Update Rollup 8. For a complete list of supported scenarios, click here.
  • Ability to set quotas for external IP addresses
    With Update Rollup 7, we announced support for multiple external IP addresses per virtual network, but the story was incomplete, as there was no option to set quotas on the number of NAT connections. With UR8, we are glad to announce end-to-end support for this functionality, as you can now set quotas on the number of external IP addresses allowed per user role. You can also manage this by using Windows Azure Pack (WAP).

Issues that are fixed in this update rollup

  • Issue 1
    Creation of Generation 2 VMs fails with the following error:

    Error (13206)
    Virtual Machine Manager cannot locate the boot or system volume on virtual machine <VM name>. The resulting virtual machine might not start or operate properly.
  • Issue 2
    VMM does not let you set the owner of a hardware profile with an owner name that contains the “$” symbol.
  • Issue 3
    HA VMs with VLAN configured on the network sites of a logical network cannot be migrated from one host to another. The following error is thrown when you try to migrate the VM:

    Error (26857)
    The VLAN ID (xxx) is not valid because the VM network (xxx) does not include the VLAN ID in a network site accessible by the host.
  • Issue 4
    The changes that are made by a tenant administrator (with deploy permissions to a cloud) to the Memory and CPU settings of a VM in the cloud through VMM Console do not stick. To work around this issue, change these settings by using PowerShell.
  • Issue 5
    When a VM is deployed and put on an SMB3 file share that’s hosted on NetApp filer 8.2.3 or later, the VM deployment process leaves a stale session open per VM deployed to the share. When many VMs are deployed by using this process, VM deployment starts to fail as the max limit of the allowed SMB session on the NetApp filer is reached.
  • Issue 6
    VMM hangs because of SQL Server performance issues when you perform VMM day-to-day operations. This issue occurs because of stale entries in the tbl_PCMT_PerfHistory_Raw table. With UR8, new stale entries are not created in the tbl_PCMT_PerfHistory_Raw table. However, the entries that existed before installation of UR8 will continue to exist. To delete the existing stale entries from the SQL Server tables, use the following SQL script:

    DELETE FROM tbl_PCMT_PerfHistory_Raw where TieredPerfCounterID NOT IN (SELECT DISTINCT tieredPerfCounterID FROM dbo.tbl_PCMT_TieredPerfCounter);

    DELETE FROM tbl_PCMT_PerfHistory_Hourly where TieredPerfCounterID NOT IN (SELECT DISTINCT tieredPerfCounterID FROM dbo.tbl_PCMT_TieredPerfCounter);

    DELETE FROM tbl_PCMT_PerfHistory_Daily where TieredPerfCounterID NOT IN (SELECT DISTINCT tieredPerfCounterID FROM dbo.tbl_PCMT_TieredPerfCounter);

  • Issue 7In a deployment with virtualized Fiber Channel adapters, VMM does not update the SMI-S storage provider, and it throws the following exception:
    Name : Reads Storage Provider
    Description : Reads Storage Provider
    Progress : 0 %
    Status : Failed
    CmdletName : Read-SCStorageProvider
    ErrorInfo : FailedtoAcquireLock (2606)This occurs because VMM first obtains the Write lock for an object and then later tries to obtain the Delete lock for the same object.
  • Issue 8
    For VMs with VHDs that are put on a Scale out File Server (SOFS) over SMB, the Disk Read Speed VM performance counter incorrectly displays zero in the VMM Admin Console. This prevents an enterprise from monitoring its top IOPS consumers.
  • Issue 9
    Dynamic Optimization fails, leaks a transaction, and prevents other jobs from executing. It is blocked on the SQL Server computer until SCVMM is recycled or the offending SPID in SQL is killed.
  • Issue 10
    V2V conversion fails when you try to migrate VMs from ESX host to Hyper-V host if the hard disk size of the VM on the ESX host is very large. The following mentioned error is thrown:

    Error (2901)
    The operation did not complete successfully because of a parameter or call sequence that is not valid. (The parameter is incorrect (0x80070057))
  • Issue 11
    Live migration of VMs in an HNV network takes longer than expected. You may also find pings to the migrating VM are lost. This is because during the live migration, the WNV Policy table is transferred (instead of only delta). Therefore, if the WNV Policy table is too long, the transfer is delayed and may cause VMs to lose connectivity on the new host.
  • Issue 12
    VMM obtains a wrong MAC address while generating the HNV policy in the deployments where F5 Load Balancers are used.
  • Issue 13
    For IBM SVC devices, enabling replication fails in VMM because there is a limitation in SVC in which the name of the consistency group should start with an alphabetical character (error code: 36900). This issue occurs because while enabling replication, VMM generates random strings for naming the “consistency groups” and “relationship” between the source and the target, and these contain alphanumeric characters. Therefore, the first character that’s generated by VMM may be a number, and this breaks the requirement by IBM SVC.
  • Issue 14
    In Update Rollup 6, we included a change that lets customers have a static MAC address even if the network adapter is not connected. This fix did not cover all scenarios correctly, and it triggers an exception when there’s a template with a connected network adapter, and then you later try to edit the static address in order to disconnect the network adapter.
  • Issue 15
    Post Update Rollup 6, as soon as a host goes into legacy mode, it does not come back to eventing for 20 days. Therefore, the VM properties are not refreshed, and no events are received from HyperV for 20 days.This issue occurs because of a change that’s included in UR6 that set the expiry as 20 days for both eventing mode and legacy mode. The legacy refresher, which should ideally run after 2 minutes, now runs after 20 days; and until then, eventing is disabled.Workaround:
    To work around this issue, manually run the legacy refresher by refreshing VM properties.
  • Issue 16
    Post-UR7, deleting a virtual network does not correctly clean up the cluster resources for the Network Virtualization Gateway. This causes the cluster role (cluster group) to go into a failed state when a failover of the HNV gateway cluster role occurs. This causes a failure status on the gateway
