Hyper-V novosti u Windows Serveru vNext Romeo Mlinar, Ekobit

Dati detaljan pregled novosti koje dolaze s Hyper-V u Windows Serveru Technical Preview Ovo nije… Kompletan pregled svih Hyper- V značajki koje će biti dostupne u finalnoj verziji Windows Servera Cilj prezentacije!

Hot add and remove for network adapters and memory Virtual Machine Configuration Version New virtual machine configuration file format Production checkpoints Hyper-V Manager improvements Integration Services delivered through Windows Update Linux secure boot Rolling Hyper-V Cluster Upgrade Sadržaj

Network adapters – can be added and removed from Generation 2 virtual machines while they are running. Memory – for Windows Server Technical Preview guests, you can now increase and decrease the memory assigned to virtual machines while they are running. Hot add and remove

Demo: Hot Add Memory - NIC

You can name individual network adapters in the virtual machine settings – and see the same name inside the guest operating system. PowerShell in host: PowerShell in guest: Network Adapter Identification Add-VMNetworkAdapter -VMName “TestVM" -SwitchName "Virtual Switch" -Name "Fred" -Passthru | Set-VMNetworkAdapter -DeviceNaming on Add-VMNetworkAdapter -VMName “TestVM" -SwitchName "Virtual Switch" -Name "Fred" -Passthru | Set-VMNetworkAdapter -DeviceNaming on Get-NetAdapterAdvancedProperty | ?{$_.DisplayName -eq "Hyper-V Network Adapter Name"} | select Name, DisplayValue

Hyper-V will not automatically upgrade virtual machines Upgrading a virtual machine is a manual operation that is separate from upgrading the host Individual virtual machines can be moved back to earlier versions, until they have been manually upgraded Virtual Machine Configuration Version

PowerShell only: Virtual Machine Configuration Version Update-VMConfigurationVersion vmname Or Update-VmConfigurationVersion vmobject Update-VMConfigurationVersion vmname Or Update-VmConfigurationVersion vmobject

After you upgrade the virtual machine configuration version, you cannot move the virtual machine to a server running Windows Server 2012 R2 You cannot downgrade the virtual machine configuration version back from version 6 to version 5 The virtual machine must be turned off in order to upgrade the virtual machine configuration This cmdlet is blocked on a Hyper-V Cluster, when the cluster functional level is Window Server 2012 R2 After the upgrade the virtual machine use the new configuration file format Virtual Machine Configuration Version

Secure boot may not work on Generation 2 virtual machine after upgrade Solution: Virtual Machine Configuration Tech Preview Bug Set-VMFirmware "VMName" -SecureBootTemplate MicrosoftWindows

Demo: Upgrade VM Configuration Version

Binary format for efficient performance at scale Resilient logging for changes New file extensions:.VMCX and.VMRS New virtual machine configuration file format

Delivers the same Checkpoint experience that you had in Windows Server 2012 R2 – but now fully supported for Production Environments Uses VSS instead of Saved State to create checkpoint Restoring a checkpoint is just like restoring a system backup Production checkpoints

Demo: Checkpoint

When you add a new virtual hard disk to a virtual machine that is being replicated – it is automatically added to the no-replicated set. This set can be updated online. Replica Support for Hot Add of VHDX Set-VMReplication "VMName" -ReplicatedDisks (Get-VMHardDiskDrive "VMName")

Connecting via WinRM Support for alternate credentials Requires that you have CredSSP enabled on server and client ( Connecting via IP address Able to manage Windows Server 2012, 2012 R2 and Technical Preview from a single console. Hyper-V Manager improvements Multiple improvements to make it easier to remotely manage and troubleshoot Hyper-V Servers

I can’t see all the virtual machines in Hyper-V Manager! Solution Hyper-V Manager Tech Preview Bug get-vm | ?{$_.heartbeat -eq "OKApplicationsUnknown"} | Disable-VMIntegrationService "Heartbeat"

Integration Services Delivered through Windows Update Windows Server 2012 R2: VM drivers (integration services) updated with each new host release Require that VM driver version matches the host Drivers shipped with host operating system Windows Server Technical Preview: VM drivers (integration services) updated when needed Require latest available VM drivers for that guest operating system Drivers delivered directly to the guest operating system via Windows Update

Providing kernel code integrity protections for Linux guest operating systems. Works with: *Ubuntu and later *SUSE Linux Enterprise Server 12 Linux secure boot

PowerShell to enable this: Linux secure boot Set-VMFirmware "Ubuntu" -SecureBootTemplate MicrosoftUEFICertificateAuthority

DEMO: Linux secure boot

Prednosti nadogradnje Hyper-V klastera s WS2012 R2 na WS TP: * bez novog hardvera * bez prekida rada * mogućnost povratka, (roll-back) ukoliko ima potrebe Rolling Hyper-V Cluster Upgrade

Windows Server 2012 R2: * Introduced the ability to limit maximum IOPs for an individual virtual hard disk Storage Quality of Service (QoS)

Windows Server Technical Preview: Leveraging Scale Out File Server to allow you to: * Define IOPs reserves for important virtual hard disks * Define a IOPs reserve and limit that is shared by a group of virtual machines / virtual hard disks Storage Quality of Service (QoS)

Demos: Distributed Storage QoS & Linux
