To enter your PTR records correctly you have to use an elevated command line with the dnscmd tool.

example:

For a reverse DNS of 111.111.111.10

dnscmd 127.0.0.1 /recordadd 128/25.111.111.111.in-addr.arpa 10 PTR subdomain.domain.com

SELECT *

FROM [vmwvdb].dbo.VPX_ENTITY

Copy the ID for use in the next query as 'VM-###'

 

SELECT *

FROM [vmwv composer db].dbo.SVI_REPLICA

where [REPLICA_MOID] = 'VM-###'

 

Copy the Replica_ID for use in next query

,[REPLICA_ID]

FROM [vmwv composer db].dbo.SVI_SIM_CLONE

where [REPLICA_ID] ='11111111-aaaa-1111-aaaa-111111111111'

 

You should now have the VM name if it still exists in the database.

    Migration is almost 2x faster than 4.1

    Empty disk is created on target vmfs, IO is written to both disks, and mirroring is started to move disk
    Pause and resume time for VM moving over storage vMotion is now controlled and never more than 2 seconds

    Snapshots
    Preserve the state of a VM
    config state
    memory state
    disk state

    Components:
    Snapshot descriptor file *.vmsd
    Snapshot config file *.vmsn
    snapshot delta disk *-delta.vmdk

    Snapshot File Placement:
    Descriptor and config file in VM home or SnapshotDirectory
    Delta disk in same location as the parent disk

    vSphere 5.0 supports storage vMotion for linked VMs

    RoadMap:
    Simultaneous vMotion and Storage vMotion
    Inter-vDS vMotion and Storage vMotion
    Inter-vCenter vMotion and storage vMotion
    vMotion and Storage vMotion across geographies

    Not all applications should use ThinApp

    Follow the ThinApp Design Process
    Listen to and document the customer pain points
    Don't be afraid of ThinApp Steaming
    Reuse existing deployment infrastructure
    Don't be afraid of 3rd Party Tools

    Use Case Definition
    Target App List
    Application Integration Design
    Application Management Design
    Packaging Infrastructure Standards
    Deployment Infrastructure Design

    ThinApp Bandwidth requirements:
    ThinApp Streaming Workload is the traffic consumed by the application during the launch process
    ThinApp Payload is the data containing the runtime components only
    TCP/IP Overhead necessary to facilitate the ThinApp Streaming Process

    ThinApp Network Impact Study Guide and ThinApp Repository Best Practices will be released soon
    PowerShell can be used to Inventory deployed and remove deployed ThinApps

    In place updates:  Current version renamed to .1 update ran as .msi

    App1.1  App1.MSI

    Dependancies are included in the ThinApp.  Multiple versions of Java can be packaged for different ThinApps and used on the same desktop.

    Using DFS to replicate ThinApps works well

    Liquidware Labs Profile Unity - ThinApp deployments and Persona management

    ThinApp Factory, new version of the ThinApp Converter
    Automatic conversion of MSI into ThinApps (coming soon)

    Horizon App Manager
    Phase 1 Saas based applications
    Phase 2 ThinApp Management and Distribution (coming soon)

    View client can't connect

    Common Issues:
    Logon failure
    Black Screen
    Poor quality display
    Randomly Disconnected Session

    Troubleshoot with:
    Connection Broker Logs ( Client logs?)
    Event database
    Look for:
    Client Connects
    Client sends user/pw
    Broker authentication
    User has authenticated to Broker
    Use the Session ID

    Domain 2: Desktop Not Available

    Common Issues:
    No Desktop Available
    Pool provisioning issues
    Agent not communicating with broker
    User sat at desktop login screen (SSO)

    Troubleshoot with:
    Connection Broker/View Agent logs
    Event Database

    Look for:
    Broker desktop request
    Broker allocates session to user
    Broker attempts SSO
    Broker starts session on VM
    Agent responds
    Broker provisioning error

    Domain 3: Broken Broker

    Look for:

    vCenter Server Connectivity
    VS_DOWN events
    View Composer

    Connect Server Logs
    tracker REJOIN messages - JMS connectivity
    tracker RESYNC messages - messages being delayed

    Domain 4: Why is my desktop so slow?

    Common Issues:
    Storage IO Bottleneck
    20ms or less disk latency expected
    Memory contention
    CPU contention
    Network Issues

    Look at:
    vCenter Server
    3rd Party Tools

    What to look for:
    VM %READY Time(ESXTOP)
    Swapping/Ballooning
    VMs per VMFS LUN (SCSI reservations)

    The most complex decisions need to be made first
    Operating Systems
    Windows 7 = Windows XP (x) 1.25 resources when optimized
    Use Case > Personal desktop and pool > Pod and Block > VMware infrastructure > Storage Design > User access Device

    Storage Design Considerations

    Server Workload
    DR
    OS
    Disposable disks
    Workload IOPS 2.5x standard deviation for design
    Max footprint
    Repositories - Home Dirs, Persistent Disks, Profile Stores, Transfer server, templates, applications

    Non functional specifications

    Manageability
    Security
    Availability
    Recoverability
    Performance
    Users Love for system, dislike for change
    Migration

    Design checklist

    Simplicity
    User involvement
    Balanced business and technical best practice
    Design rationales
    Clarity over ambiguity
    Reusable
    Simplicity

    Best Practices

    OS optimization
    Antivirus resource demands
    Storage design
    PCoIP integration
    Business case
    Avoid the meandering path to failure
    PCoIP one level below VOIP

    Assessment > PoC > Pilot > Production design > Production Deployment
