  • Microsoft Hyper-V Server 2012 and 2012 R2
  • Windows Server Technical Preview
  • Microsoft Hyper-V Server Technical Preview
  • Microsoft Azure

The new integration tools add support for the following Linux releases:

  • Red Hat Enterprise Linux 5.5-5.11 32-bit, 32-bit PAE, and 64-bit
  • Red Hat Enterprise Linux 6.0-6.7 32-bit and 64-bit
  • Red Hat Enterprise Linux 7.0-7.1 64-bit
  • CentOS 5.5-5.11 32-bit, 32-bit PAE, and 64-bit
  • CentOS 6.0-6.7 32-bit and 64-bit
  • CentOS 7.0-7.1 64-bit
  • Oracle Linux 6.4-6.7 with Red Hat Compatible Kernel 32-bit and 64-bit
  • Oracle Linux 7.0-7.1 with Red Hat Compatible Kernel 64-bit

Also remember that many Linux distributions already have Integration tools included with them and there is no need for a separate install.
You can find the list of supported Linux versions over here.

Update rollup 3 for SCVMM 2012R2 & update rollup 7 for SCVMM 2012SP1 released

Update rollup 3 for SCVMM 2012R2 has been released. It includes multiple resolved issues and adds support for Ubuntu Linux 14.04

Issues that are fixed in this update rollup

  • Total storage for a User role is reported incorrectly. For example, the User role can use only half of the allowed quota.
  • A host cluster update fails intermittently because of a locked job.
  • Virtual machine (VM) refreshers do not update highly available virtual machines (HAVMs) after failover to another node.
  • A cluster IP address for a guest cluster configuration in a Hyper-V Network Virtualization (HNV) environment is not updated correctly by using HNV policies during failover. For more information about this issue, see the following article in the Microsoft Knowledge Base:2981736 (http://support.microsoft.com/kb/2981736/ )
    The cluster IP address in an HNV environment is updated incorrectly during failover
  • Server Message Block (SMB) shares may not be usable by high availability (HA) workloads if they are also connected to stand-alone hosts.
  • Storage objects discovery does not occur on a Virtual Machine Manager server if the discovery item is too big.
  • A Virtual Machine Manager job that assigns network service backend connectivity fails.
  • Enable maintenance mode fails when you evacuate failed-state VMs.
  • The Virtual Machine Manager service cannot be restarted because of database corruption.
  • The ZH-TW language incorrectly appears in the tooltip of the VM Network icon.
  • Library refresher rewrites the alternative data stream on every file during every update.
  • For iSCSI hardware storage-based array, when the MaskingPortsPerView property option is set to “multi-port per view,” the target endpoint is not obtained as the port address.
  • The virtual hard disk (VHD) is left in the source folder after storage migration is completed.
  • The addition of a bandwidth limitation to an existing virtual private network (VPN) connection is not added to the generated script.
  • A VM that is attached to an HNV VM network loses connectivity when it is live migrated to another node in the failover cluster that is not currently hosting other VMs that belong to the same VM network.
  • VM network shared access is lost after a service restart or an update interval.
  • The Remove-SCFileShare command fails for a network-attached storage SMI-S provider.
  • Setting the template time zone to UTC (GMT +0:00) is incorrectly displayed as “Magadan Standard Time.”
  • The System Center 2012 R2 Virtual Machine Manager crashes when you add groups that contain the at sign (@) character in User roles.
  • VM deployment fails in a VMWare environment when you have virtual hard disk (.vmdk) files of the same size in your template.
  • Deployment of an application host on HAVMM fails and generates a 22570 error.
  • Live migration of an HAVM cross cluster creates a duplicate VM role in the target cluster.
  • An error occurs when you apply physical adapter network settings to a teamed adapter.
  • A VMM agent crashes continuously when the HvStats_HyperVHypervisorLogicalProcessor query returns a null value.
  • A host refresh does not update the VMHostGroup value of a VMWARE cluster after the cluster is moved from VCENTER.
  • VMM reports an incorrect Disk Allocation size for dynamic VHDs that are mapped to a virtual machine.
  • A VMM service template script application does not work for a self-service role.
  • VM creation fails if Virtual Machine Manager undergoes failover during the creation process.
  • The Access Status value of a file share is incorrect in the user interface.
  • The Virtual Machine Manager service crashes because of an invalid ClusterFlags value.
  • VMs cannot be deployed from a service template to a cloud across multiple host clusters (multiple datacenters).

Features that are added in this update rollup

  • This update includes a Linux guest agent upgrade to support the following new operating systems:
    • Ubuntu Linux 14.04 (32-bit)
    • Ubuntu Linux 14.04 (64-bit)
  • This update also includes the following:
    • Host DHCP extension driver upgrade
    • Several performance improvements
    • Several Management Pack package improvements

Also released is update 7 for SCVMM 2012 SP1.

Issues that are fixed in this update rollup

Virtual Machine Manager

  • A host refresh does not update the VMHostGroup value of a VMWARE cluster after the cluster is moved from VCENTER.
  • A service reconfiguration does not finish when the servicing generic command executable (GCE) has an application payload.

Hyper-V 2012R2 Extended Linux Support

In every release of Hyper-V Microsoft has improved support for Linux.
The support of Linux is being improved in Hyper-V 2012R2 with the following features:

  1. Linux Synthetic Frame Buffer driver – Provides enhanced graphics performance and superior resolution for Linux desktop users.
  2. Linux Dynamic memory support – Provides higher virtual machine density/host for Linux hosters.
  3. Live Virtual Machine Backup support – Provisions uninterrupted backup support for live Linux virtual machines.
  4. Dynamic expansion of fixed size Linux VHDs – Allows expansion of live mounted fixed sized Linux VHDs.
  5. Kdump/kexec support for Linux virtual machines – Allow creating kernel dumps of Linux virtual machines.
  6. NMI (Non-Maskable Interrupt) support for Linux virtual machines – Allows delivery of manually triggered interrupts to Linux virtual machines running on Hyper-V.
  7. Specification of Memory Mapped I/O (MMIO) gap – Provides fine grained control over available RAM for virtual appliance manufacturers.

In a nutshell what this means is that you can have dynamic memory working on Virtual Linux Machines, perform live backups of the Linux VM’s without pausing or interrupting the activity of the servers, dynamically enlarge VM disks without interrupting the VM and more.

This basically means that you can run Linux VM’s in a hyper-V environment with the same features as Windows provisioned VM’s.
I can’t wait to see all those virtual appliances out there being customised for Hyper-V.
