1 Management Pain points now Existing tools: Do not map to virtual environments Provisioning Backup Health monitoring Performance monitoring / management Do not consider physical - virtual relationship Ownership Patching and servicing

2 Virtual Server Backup and Recovery Do you need to backup VMs? Because a VM is a single file (*.vhd), it is very easy to use backup methods that you cannot safely restore Issues are: Running state of vhd-file Restore unusable "snapshot" of a database Best example: Active Directory database

3 Backup of VM Three methods: - Inside VM, run backup application Treat VM as a normal physical machine - Stop VM (save state) - On host, backup vhd/vsv files - Start up VM Only short VM downtime  Not supported for DCs in VM ! - Needs: Virtual Server 2005 R2 SP1 - On host, run backup application - Copy 'open' vhd files - uses VSS and VS Writer VS Writer ensures vhd-file is in consistent state  Do NOT use without Virtual Server 2005 R2 SP1

4 Backup of VMs VSS explained Roles VSS Requestor = backup application Initiates backup action VSS Writer = Virtual Server 2005 R2 SP1 Ensures data consistency In guest (VM1) Virtual Server On host VSS Service Backup Application VSS Service "Backup VM1" 1 VS Writer SQL Server Writer Exchange Writer Snap 2 3 "Backup files" Snap 4 SnapID 5 Freeze "Unfreeze" 6 Backup Application Copy files based on SnapID 7 VSS Service

5 Scripting Virtual Server Virtual Server COM - Set virtualServer = CreateObject("VirtualServer.Application") WMI - Set vsWMIObj = GetObject("winmgmts:\\.\root\vm\virtualserver") Virtual Machine Manager PowerShell (Monad) Windows Virtualization WMI - Set WMIService = GetObject("winmgmts:\\.\root\virtualization")

7 Virtual Machine Manager Features Resource optimization Identify consolidation candidates Fast P2V Optimum workload placement on host computers Rapid provisioning Central library of virtualization components Running VMs, offline VMs, vhd-files, vnc-files Self-service provisioning Templates: create standardize VMs Automatic placement on suitable host computer Distributed storage infrastructure - uses DFS Host provisioning Uses PowerShell ("Monad") for scripting

8 Virtual Machine Manager Physical to Virtual (P2V) Identify consolidation candidates Looks at peak and average performance Configurable selection parameters Physical to virtual migration Uses fast VSS, not based on existing VSMT Support Win2000 Server and Win2003 Server Uses BITS for network transport speed Wizard based, or scripted through PowerShell

9 Virtual Machine Manager VM placement Capacity planning everywhere Used for P2V, migration, template deployment, self-service Rating scheme Hard requirement Minimum CPU, RAM needed, disk space needed, network usage Soft requirements Historic VM performance Current host performance

10 Virtual Machine Manager Offline library Contents Templates Sysprepped VHDs Standardizes deployments of VMs Virtual machines Store non-running VMs Disks ISO Scripts Architecture Distributed Multiple library servers Access through DFS Namespaces Replicated Uses DFS-R and RDC

11 Virtual Machine Manager Self-service portal Web based interface Controls management deployment End users interact with their own VMs Deployment based on templates Resource quotas set per user VMs may retire after "lease" expires
