Performance Charts in the VI Client fail to load completely

February 26, 2014 by in VMWare

Symptoms
Performance Charts in vSphere Client load only as a bitmap, with a question mark in the top right corner
No performance data is displayed

Cause
The Performance Charts feature is designed to use JS navigation-related functions provided by the browser. This issue occurs if the HTTP 1.1 option in Internet Explorer is not selected.

Resolution
This issue is resolved in vCenter Server 4.1 Update 2. For more information, see the VMware vCenter Server 4.1 Update 2 Release Notes.
 
To download vCenter Server 4.1 Update 2, see the VMware Download Center.
To work around the issue when you do not want to upgrade:

Caution: This procedure involves modifying the registry. Ensure that you have permissions to modify the registry. Incorrect changes to the registry can leave your system unstable or unable to run. Always back up the registry before editing it, and exercise caution in making changes to the registry. VMware takes no responsibility for problems that may arise.

  1. Start Internet Explorer, click Tools > Internet Option > Advanced > HTTP 1.1 Settings.
  2. Select the Use HTTP 1.1 option. 

If HTTP1.1 is disabled at a domain level via GPO, manually override this registry settings to resolve the issue:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\CurrentVersion\Internet Settings:

EnableHttp1_1 > Use HTTP 1.1
ProxyHttp1.1 > Use HTTP 1.1 through proxy connections

Alternatively, try adding the IP address 127.0.0.1 to the trusted sites list in Internet Explorer:

  1. Start Internet Explorer.
  2. Click Tools > Internet Option.
  3. Click the Security tab.
  4. Click Trusted Sites and then click Sites.
  5. Type 127.0.0.1 in the Add this website to the zones textbox.
  6. Click Add.
  7. Click Close.
  8. Click OK.

USB support for ESX/ESXi 4.1

November 15, 2011 by in Ostatní, VMWare

ESX 4.1 supports USB device passthrough from an ESX or ESXi to a virtual machine.
This article provides information about USB device passthrough
requirements and limitations, as well as steps to add a USB controller
and a USB device.
Requirements
USB device passthrough requires:

  • Virtual hardware version 7 or higher
  • A USB Arbitrator
  • A USB controller
  • A USB device or device hub

Limitations
The USB Controller has these limitations:

  • USB controller hardware and modules that support USB 2.0 and USB 1.1 devices must be present on the host.
  • You can add only one virtual USB controller to each virtual machine.
  • The USB arbitrator can monitor a maximum of 15 USB controllers.
    If your system includes an additional number of controllers and you
    connect USB devices to these controllers, the devices are not available
    to the virtual machine.
  • You must add the USB controller to the virtual machine before you can add a USB device.
  • You must remove all USB devices before you remove the controller.

USB devices have these limitations:

  • You can add multiple USB devices to a virtual machine that
    resides on an ESX/ESXi host to which the devices are physically
    attached.
  • A USB device is available to only one virtual machine at a time.
  • You can add up to 20 USB devices to a virtual machine.
  • Unsupported USB devices may not interact as expected with other ESX/ESXi features. For a list of supported USB devices.
  • Before you hot add memory, CPU, or PCI devices, you must remove
    any USB devices. Hot adding these resources disconnects USB devices,
    which may result in data loss.
  • When you suspend and resume a virtual machine, USB devices behave as if they have been disconnected, then reconnected.
  • The virtual machine cannot boot from the attached USB device.

Adding a USB controller and a USB device
To add a USB controller in a virtual machine running operating system:

  1. Right-click the virtual machine and click Edit Settings.
  2. Click Add.
  3. Select USB Controller and click Next.
  4. Click OK.
  5. Go to Control Panel > Administrative Tools > Disk Management.
  6. Right-click the USB disk and assign a letter.

To add a USB device:

  1. Right-click the virtual machine and click Edit Settings.
  2. Click Add.
  3. Select USB Device and click Next.

Thats all

How copy, migrate from VMWare Server or VMWare Workstation to ESXi Server

And how migrate virtual disks?

1. Access the ESXi console
2. Press Alt+F1
3. Type the word "unsupported", and press enter
4. Enter the root password.
5. Run the vmkfstools command to convert your image:
# vmkfstools.pl -i /vmfs/volumes/datastore1/VMWAREFile.vmdk /vmfs/volumes/datastore1/VMWAREFile_Converted.vmdk

6. Move the resulting *two* files to the location you want on the datastore, with the name you want
VMWAREFile_Converted.vmdk (small metadata file, text format)
VMWAREFile_Converted-flat.vmdk (large disk file, binary format)
7. Type exit to log out of the unsupported console
8. Press ALT+F2 to get to the normal interface
9. Add the disk to an existing machine using an "existing disk", and reference the converted file (e.g. VMWAREFile_Converted.vmdk)
