  15. Open Discussion – VMware is standardizing on the ESXi hypervisor architecture

  16. Open Discussion – Q&A Problem after upgrading to 4.1 Virtual Center was slow and search broke after upgrade – Check the memory for the TomCat Service. We had to increase it to 4GB. tomcat6.exe

  17. Open Discussion – OS Standards OS Standards W2K C: 10 D: 20GB RAM – 1GB W2K3 C: 20GB D: 20GB RAM – 2GB W2K8 C: 30GB D: 30GB RAM – 3GB Disable COM ports not being used SQL and Citrix Servers – Added memory to the reservations. 1024MB for SQL 2048MB for Citrix

  18. Open Discussion – OS Standards Check and upgrade Tools during power cycle Adding multiple drives: Run diskpart to align the drive to 64bit offset. Diskpart Command: “Create part primary align 64” Startup Timeout: Deselect BOOT.INI timeout Where: My Computer \ Properties \ Advanced \ Startup & Recovery Computer Description: Add what the system/application is. Where: My Computer \ Properties \ Advanced \ Computer Name IIS installed:If IIS is installed, do the following. Move IIS directories to D:\ (including logfiles) Delete default files in .\wwwroot

  19. Open Discussion – Q&A • Windows 2008-64Bit running SQL 2005-64bit • C: 50GB - system • D: 50GB - SQL • E: CD • F: 30GB – Logs • G: 50GB – Update MGR Store • Create two separate databases. VCenterDB and UpdateDB • Created a 32bit DSN for vCenterDB and UpdateDB. (No Longer Needed, 4.1 is 64 bit compatible) • NOTE: • The default install location on 64-bit operating systems is C:\VMware. • Run the 32-bit ODBC Administrator application, located at [WindowsDir]\SysWOW64\odbcad32.exe. • Use the application to create your DSN. • You now have a DSN that is compatible with vCenter Server. When the vCenter Server installer prompts you for a DSN, select the 32-bit DSN. • Disabled WWW service. VCenter uses tomcat and communicates on port 80 • Installed VCenter on default drive C: because it uses application data for necessary files. • Set the SQL Server install to use TCP/IP and named pipes. • Run the server under system account. • Update Manager is connected to SQL Database UpdateDB • Patches are downloaded and saved to G:\updatemanager • Created an alias to connected to ***VC***01 – VirtualCenter or Vcenter • ESX Install - How to install ESX 4.pdf

  20. Open Discussion – Q&A Q: My performance is slow on Windows 2008 R2 Servers.  A: The most effective solution is to update to ESX 4.0 Update 1, which provides a new WDDM driver that is installed with VMware Tools and is fully supported. After a VMware Tools upgrade, you can find it in C:\Program Files\Common Files\VMware\Drivers\wddm_video. KB Article: 1011709 Did you try to install the WDDM driver or to just disable the SVGA driver? Typically I have had customers install the WDDM driver and increase the video RAM to 32MB, to see a better improvement in video response on 2008 R2 machines. http://kb.vmware.com/selfservice/microsites/search.do?cmd=displayKC&docType=kc&externalId=1011709&sliceId=1&docTypeID=DT_KB_1_1&dialogID=43856896&stateId=0%200%2043008426 Note: By default Windows 2008 uses the SVGA driver so you must manually configure the WDDM driver using the path above. If you cannot update to ESX 4.0 Update 1, deselect the driver included with ESX 4.0. When you install VMware Tools, select Custom or Modify in the VMware Tools installation wizard, then deselect the SVGA (XPDM) driver. Alternatively, remove the SVGA driver from the Device Manager after installing VMware Tools.

  21. Open Discussion – Q&A Q: I can’t add a 2008 server to the domain during customization process: A: For some reason the unattended XML doesn’t like the same format as the unattended.txt from 2003. I used “vmware.org" in the domain name field instead of “vmware” AND changed the username from either “vmware\domainadd" or “vmware.org\domainadd" to just “domainadd". This seems to have fixed the issue Q: Do I need to reload my ESX Hosts to upgrade to 4.0? A: Depends on your current setup. The service console VMDK requires at least 8.4GB of available space. VMware recommends that you select a datastore that is local to the ESX host. The service console must be installed on a VMFS datastore that is resident on a host's local disk or on a SAN disk that is masked and zoned to that particular host only. The datastore cannot be shared between Hosts. NFS and software iSCSIdatastores are not supported as the destination for the ESX 4.0 service console VMDK.

  22. Open Discussion – Q&A • VM blue screening after updating VMWare tools • Troubleshooting procedures/fix • W2K systems blue screened after tools upgrade. Message mentioned that system was unable to find system drive. • Booting with last known good or in safe mode was unsuccessful. • Connect drive to an existing vm to investigate • Looked for files that had been updated at the time of crash • Started with the setupapi.log file in winnt\temp • Found entries mentioning the install of vm device drivers into winnt\system32\drivers folder • Compared the version of vmscsi.sys to other versions. My guess was that it needed to go back to the version of the same OS and same stage of VMware tools. In this case, it was 2000 and out of date VMware tools. • Logged into a computer that met the criteria. Versions did not match. • Unable to copy the file because the file was in use (makes sense) • **NOTE** A copy of the VMware drivers is stored in c:\program files\vmware\vmware tools\drivers\ • Copied the vmscsi.sys file and used it to replace the one on the machine that was blue screening. (winnt\system32\drivers) • Removed drive from VM & powered on vm that was blue screening. • Great Success! Big sigh of relief • Reinstalled VMtools and updated virtual hardware.

  23. Open Discussion – Q&A Q: Do you need any special licenses to add the Nexus 1000 stuff? A: No additional licenses needed for the Nexus 1000 switch Q: Can I migrate / svmotion a thin provisioned guest? A: Yes Q: Can I migrate / svmotion a guest with a RAW disk attached? A: Yes  Q: How to upgrade to latest agents on HP. A: Use 800a to uninstall, then upgrade to latest. Q: Can I expand the C: drive without taking down the server? 2000 & 2003 32bit only (no 64-bit) A: Yes you can by using ExtPartfrom Dell. http://h0bbel.p0ggel.org/howto-using-extpart-to-expand-windows-server-2003-vm-boot-volume http://support.dell.com/support/downloads/download.aspx?c=us&cs=19&l=en&s=dhs&releaseid=R64398&formatcnt=2&fileid=83929 http://taylor.freeshell.org/2009/06/dell-extpart.html

  24. Open Discussion – Q&A Performance Enhancements – VShpere is Alua aware – “Asymmetric logical unit access” Check with your storage provider to find out if they are “alua” aware. This helps with fail-over and better performance. EMC ?? HP – EVA 8000 NetApp

  26. Open Discussion – Q&A Disk Alignment Problems http://www.vmware.com/pdf/esx3_partition_align.pdf NetApp – Free tool Vizioncore – Pay per processor We use NFS on a NetApp 3040 for our datastores. They are 1.5TB in size and have de-duplication enabled. We have around 200 VMs per datastore. We were seeing performance problems on VMs as well as build performance issues with hosts that stored their data on the same NetApp. We opened a case with NetApp and the performed an analysis of the performance issue. They were seeing a lot of misaligned I/O which was traced back to the VMDKs. The tool works pretty well, but there are some limitations. It will not work with VMs that have snapshots. All snapshots will need to be deleted before aligning the VMDK. It does not work with VMDKs that have Windows Dynamic partitions. It works with Linux and Solaris 10 VMs, but after realignment, you have to boot the VM off a rescue CD and reinstall the grub boot manager.
