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).
How do I use this functionality?
To set the quota for a user role:Set-UserRole –UserRole UserRoleObject –NATConnectionMaximum MaxNumber
To remove the quota for a user role:Set-UserRole –UserRole UserRoleObject –RemoveNATConnectionMaximum
Sample cmdlets:Set-UserRole –UserRole $UserRoleObject –NATConnectionMaximum 25
Set-UserRole –UserRole $UserRoleObject –RemoveNATConnectionMaximum
- Support for quotas for checkpoints
Before UR8, when you create a checkpoint through WAP, VMM does not check whether creating the checkpoint will exceed the tenant storage quota limit. Before UR8, tenants can create the checkpoint even if the storage quota limit will be exceeded.
Sample scenario to explain the issue before UR8
Consider a case in which a tenant administrator has a storage quota limit of 150 GB. Then, she follows these steps:
- She creates two VMs of VHD size 30 GB each (available storage before creation: 150 GB, post-creation: 90 GB).
- She creates a checkpoint for one of the VMs (available storage before creation: 90 GB, post-creation: 60 GB).
- She creates a new VM of VHD size 50 GB (available storage before creation: 60 GB, post-creation: 10 GB).
- She creates a checkpoint of the third VM (available storage before creation: 10 GB).
Because the tenant administrator has insufficient storage quota left, VMM should, ideally, block the creation of this checkpoint (step 4). But before UR8, VMM lets tenant administrators create the checkpoint and exceed the limit.
With Update Rollup 8, you can now rest assured that VMM will handle checking the tenant’s storage quota limits before you create a checkpoint.
- Ability to configure static network adapter MAC address during operating system deployment
With Update Rollup 8, we now provide the functionality to configure static network adapter MAC addresses during operating system deployment. If you have ever done Bare Metal provisioning of hosts and ended up having multiple hosts with the same MAC addresses (because of dynamic IP address assignment for network adapters), this could be a real savior for you.
How do I use this functionality?
New-SCPhysicalComputerNetworkAdapterConfig -UseStaticIPForIPConfiguration -SetAsGenericNIC -SetAsVirtualNetworkAdapter -IPv4Subnet String -LogicalSwitch Logical_Switch -VMNetwork VM_Network -MACAddress MAC_Address
To configure a static MAC address, you can specify the MACAddress parameter in the previous PowerShell cmdlet. If no MAC address parameter is specified, VMM configures it as dynamic (VMM allocates Hyper-V to assign the MAC Address.). To choose MAC from the default VMM MAC address pool, you can specify the MAC address as 00:00:00:00:00:00., as in the following screen shot:
- Ability to deploy extended Hyper-V Port ACLs
With Update Rollup 8 for VMM, you can now:
- Define ACLs and their rules
- Attach the ACLs created to a VM network, VM subnets, or virtual network adapters
- Attach the ACL to global settings that apply it to all virtual network adapters
- View and update ACL rules configured on the virtual network adapter in VMM
- Delete port ACLs and ACL rules

- Support for storage space tiering in VMM
With Update Rollup 8, VMM now provides you the functionality to create file shares with tiers (SSD/HDD).
For more information, see Knowledge Base article 3101159 .
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 7
In 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.
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, as in the following screen shot:
