• Guest OS:
– Runs all major x86 OSes
– 3.6GB RAM
– 4 NICs
– 56.5TB storage (IDE -SCSI)
– 2-N failover MSCS clustering• VM to VM same VS Host
Server• SCSI limits cluster size• ISCSI will support more
cluster nodes and VM to VM clusters across hosts.

Agenda
• Overview and Architecture• Configuration and Capabilities
Configuration and Capabilities Virtual Machine Files• Virtual Machine configuration file
– XML file contains all configuration metadata– Can be copied to another host server for redeployment
• Virtual Hard Disk file– Is the “hard disk” in the virtual machine– Can be copied to another host server for redeployment
• Virtual Network configuration file– XML file contains all configuration metadata– Can be copied to another host server for redeployment
Configuration and Capabilities Virtual Machine States
• On/Off• Paused• Saved/Restored/Discard• Reset
Configuration and Capabilities Disk Drives
• Four disk drive types – Dynamically expanding– Fixed size– Difference drive – Linked drive – Uses a physical drive
• Undo disks– Updates are committed or discarded at shutdown
Configuration and Capabilities Virtual Machine Remote Control
• VMRC Protocol– Access to BIOS– Operating System Independent– Service hosted by Virtual Server– Can be encrypted via SSL
• RDP Protocol– No Access to machine BIOS– Limited to OS that hosts Terminal Services
Monitoring Status & Resource AllocationScripting
• COM API – Web console = reference implementation– Fully-documented: 28 classes and 363 calls– Support for all COM-capable languages
• XML configuration files– Extensible VM descriptors– Management solutions can
leverage/enrich metadata
Configuration and CapabilitiesCPU Resource Allocation
• Relative Weight– Most often used– Virtual Server assigns CPU time
• Reserved Capacity– Minimum CPU threshold
• Maximum Capacity– Maximum CPU threshold
