Agenda
- Slide 3
- Streamed Virtual Machine Setup Wizard
- Slide 4
- XenDesktop and Streamed VM Setup Wizards
- Slide 5
- Functionality Creates VMs from template on hypervisor host(s)
Creates PVS targets within specified Device Collection Creates AD
computer accounts or import existing ones Assigns shared vDisk
Streamed Virtual Machine Setup Wizard
- Slide 6
- Requirements One PVS Collection and one vDisk in standard mode
At least one host with one VM template One template per host

- Slide 10
- New VHD types New vDisk lifecycle operations and modes New
target device types How does Versioning Work?
- Slide 11
- The existing VHD file types are preserved Fixed Dynamic New VHD
types VHD Base Disk, *.vhd (either fixed or dynamic VHD) VHD
Differencing disk, *.avhd New VHD Types
- Slide 12
- VHD Chains Examples
- Slide 13
- VHD Chains Read/Write Access
- Slide 14
- VHD Chains Multiple Streams
- Slide 15
- Properties file for each version to retain printer
configurations Cache type will be determined by top version Lock
file will exist for each version Properties & Lock Files
- Slide 16
- Maintenance Test Production Standard Mode Private Mode vDisk
Lifecycle Management
- Slide 17
- New Target Device Types Maintenance Test Production
- Slide 18
- Lifecycle operations New Promote Revert VHD chain operations
Merge (2 ways) Delete Replication (Import / Export) Lifecycle and
VHD Chain Operations
- Slide 19
- vDisk Versioning User Interface IconVersion Maintenance Test
Pending Current Production Obsolete
- Slide 20
- vDisk Versioning User Interface
- Slide 21
- Lifecycle Operations Promoting a vDisk Version Promoting a
Maintenance to Test or Production
- Slide 22
- Lifecycle Operations Reverting a vDisk Version Reverts a
Production to Maintenance or Test Reverts a Test into
Maintenance
- Slide 23
- VHD Chain Operations - Merge Consolidate differencing disks
into Another differencing disk New base disk No Maintenance version
can exist No Test version(s) can exist
- Slide 24
- VHD Merge Consolidated Differencing Disk
- Slide 25
- VHD Merge New Base Image
- Slide 26
- Automatic Merge
- Slide 27
- Automatic Merge Warning
- Slide 28
- Exporting vDisk Versions
- Slide 29
- Copy new versions to new store location Copy XML file to new
store location
- Slide 30
- Importing vDisks Versions Copy vDisk and any associated
properties files to shared storage Check vDisk versions to be added
to vDisk pool
- Slide 31
- Import and export of both versioned and unversioned vDisks,
from an existing store to a store in a different farm Import or
Export of VHDs and VHD chains Treat disks from external sources as
single VHD All differencing disks not exported with PVS must be
merged to a base disk before imported VHD Chain Operations
Import/Export
- Slide 32
- Performance The longer the VHD chain the more IOPS and memory
it will consume Upgrade and backward compatibility Upgrade ALL
SERVERS before using vDisk versioning Old target drivers specific
versions are compatible with vDisk versioning Performance
Considerations
- Slide 33
- Automated vDisk Updates
- Slide 34
- Automates updating of vDisks Electronic Software Delivery (ESD)
tools or scripts can be used: SCCM and WSUS in first release Others
including AV tools in subsequent releases Multiple supported
hypervisors XenServer, Hyper-V, ESX Multiple update modes Scheduled
Manual Automated vDisk Updates
- Slide 35
- vDisk Update Management Components
- Slide 36
- Remote vDisk Store Virtual Host ProviderOptional: ESD Server
Provisioning Services Provisioning Services designated for
Automated vDisk Updates
- Slide 37
- Configuring Image Updates (1) Enable vDisk Update in the site
properties dialog
- Slide 38
- Configuring Image Updates (2) Add a Host
- Slide 39
- Configuring Image Updates (3) Select vDisks and assign them to
VMs
- Slide 40
- Configuring Image Updates (4) Create an update task
- Slide 41
- Citrix vDisk Update Service
- Slide 42
- Add Scripting Points into Update Sequence Server Pre- update
script Prepare Image Post- update script Start VM Maintenance
Device Pre- update script Apply updates Post- update script
Shutdown Server Post-VM script Submit Image Post- update script
Update Complete
- Slide 43
- Server side Create scripts folder under installation folder
Client side names to be exact Create scripts folder under
installation folder Preupdate.bat Postupdate.bat Enabling
Scripting
- Slide 44
- Inventory and Replication
- Slide 45
- In-memory Inventory Table created at startup Keeps track of
every vDisk version in the file system Keeps track of which disks
are up to date Let admin choose replication method Examples: DFS,
PeerSync, Robocopy or scripts vDisk Inventory Service
- Slide 46
- vDisk Replication Status
- Slide 47
- Will keep PVS server out of HA if vDisk version not available
Better logon with no hanging devices Better reconnect with no Blue
Screens A graphical view to check replication status Replication
