Went from 162 cmdlets in VMM 2008 R2 to 438 in VMM 2012. They maintained backwards compatibility through aliases. The cmdlets got renamed so they don\u2019t conflict with the new Windows Server 2012 Hyper-V cmdlets.<\/p>\n
POSH is the driving force for the UI. Cmdlets are executed as jobs in VMM so there\u2019s an audit trail. Other partners, e.g. TFS or XenDesktop, integrates with VMM cmdlets for deployment.<\/p>\n
Overview of VMM 2012 system<\/u><\/strong><\/p>\n Cmdlet groups: 46 nouns<\/u><\/strong><\/p>\n Domain Join for VM<\/u><\/strong><\/p>\n You can use \u2013DomainJoinOrganizationalUnit \u201cou=, dc=\u201d to set where a new VM joins in a domain.<\/p>\n -AutolongCredential to set autologon account and \u2013AutoLogonCount to say how many times that will run.<\/p>\n These must be set at the same time. You can clean up with disableautologon.<\/p>\n UnattendSettings<\/u><\/strong><\/p>\n Looks like we can use this to customise an unattend.xml for Specialize (3) and OOBE (6) passes. Use Add)key,value) to add settings.<\/p>\n Your settings will override settings in GuestOSProfile or VMTemplate. You have to commit the settings with set-scvmtemplate (I think \u2013 quick slides) to use them.<\/p>\n Demo<\/u><\/strong><\/p>\n I<\/strong>n the demo, he wants to override a template. He gets the template. Now he creates a new temporary template. He sets the OU for it to join to. He creates runas account as the account he\u2019ll use for building the VM. He uses that for autologon. He get\u2019s the unattend object. No he adds a bunch of overrides to the template using $unattend.add(). set-scvmtemplate \u2013 vmtemplate $template \u2013UnanntedSettings $unattend) | Out-Null commits the overrides. They create a $vmconfig using new-scmconfiguration \u2013vmtemplate $template \u2013Name ($vmNamePrefix + @_config@)) | fl Name. <\/p>\n VMM still doesn\u2019t have the ability to create differencing disks so you have to use WMI to do it instead. Apparently this has been blogged. <\/p>\n He sets the disk name and location. This can be done on a per disk basis. In this cmdlet he\u2019s told it to use an existing VHD he just created using WMI. <\/p>\n Virtual Machine Configuration<\/u><\/strong><\/p>\n You can create a VM config so you can deploy very specific VM configs, different from the defaults. $VHD to get-scvirtualharddisk from the library. Then set$storageclass viariable with get-scstorageclassification. Now $ComputeTier with get-sccomputertier. Then $VMconfig with new-scvmconfiguration and the $computertier variable. $vhdconfig and get-scvirtualharddiskconfiguration and $vmconfig. setscvirtualharddiskconfiguration and $vhdconfig and $vhd and $storageclass. <\/p>\n Now $virtualnetworkadatperconfig = get-scvirtualnetworkadapterconfiguration. Setscvirtunetworkadapterconfiguration with $virtualnetadapterconfiguration. And then more stuff. Download the slide deck when it comes out in a few days.<\/p>\n Basically you build up a VM config and then you create a VM from that config.<\/p>\n There is a script on the net that will automatically sign the scripts in your VMM library. It was written for 2008 R2.<\/p>\n We\u2019re shown a demo where a script checks for expired (by date) VMs and stores them in the VMM library.<\/p>\n Hyper-V Data Exchange<\/u><\/strong><\/p>\n Can read and set the KVPs in the VM. Can read data from a VM without using the network via read. Can pass in string values to a VM regardless of power state with Set. A Key is a registry VALUE create to store DATA. The value is the DATA. And a KVPMAP is a hash table is one ore more VALUEs or DATA.<\/p>\n Cool demo where Hector writes to the registry of the VM in different power states (on, off, paused, save state).<\/p>\n VDI<\/u><\/strong><\/p>\n Jobs submitted to VMM using \u2013RunAsynchronously from one or more runspaces. Hundreds of parallel jobs. Typically used in the morning bootstorm in VDI.<\/p>\n VMM 2012 has a concept of threadpools. By default it handles 25 threads per core in the VMM server with a max of 150 (requires a monster VMM server). High number of context switches can slow performance of the VMM server. The WCF timeout is configurable (default of 120 seconds). Monitor the performance of jobs if you increase threadpools.<\/p>\n If you run asynchronously then query the job object for status. For higher throughput, use multiple threads with multiple runspaces.<\/p>\n Make sure you tune the VMM refreshers in VDI, and also in very large static environments. 4000 VMs doing a light refresh every 2 minutes and a ful refresh every 30 minutes will hammer the VMM server. <\/p>\n <\/p>\n Speakers: Hector Linares, Senior Program Manager and Susan Hill, Senior Technical Writer, MSFT Went from 162 cmdlets in VMM 2008 R2 to 438 in VMM 2012.
