Install Dell OpenManage on ESXi 5.1 host

If you have follow my guide to install the Dell Openmanage on a ESXi 4.1 host, and try the same thing on a ESXi 5.1 you will get a warning from the host saying:
This operation is NOT supported on 5.1.0 platform.

You need to install it directly on the ESXi host in 5.1 version.
So you just need to upload the Dell OM-SrvAdmin-Dell-Web-7.2.0-6945.VIB-ESX51i.zip file to the host, i will do this with WinSCP, i will put in the /tmp directory.

Then SSH to the host and run this commands:

esxcli software vib install –d /tmp/OM-SrvAdmin-Dell-Web-7.2.0-6945.VIB-ESX51i.zip

Output:

~ # esxcli software vib install -d /tmp/OM-SrvAdmin-Dell-Web-7.2.0-6945.VIB-ESX51i.zip
Installation Result
   Message: The update completed successfully, but the system needs to be rebooted for the changes to be effective.
   Reboot Required: true
   VIBs Installed: Dell_bootbank_OpenManage_7.2-0000
   VIBs Removed:
   VIBs Skipped:

After you have install the VIB packages successfully, the ESXi 5.1 host needs to be restarted. When the host is ready again, you should be able to see that UserVars.CIMvmw_OpenManageProviderEnabled is set to 1. In this location

Select the host and go to the Configuration tab. Click on Advanced Settings and find the UserVars.CIMvmw_OpenManageProviderEnabled, and check that this is set to 1. In ESXi 4.1, this is UserVars.CIMoemProviderEnabled

XenCenter – Failed to import

I have a problem with my Xencenter failed to import a OVF VM.
In XenCenter console, it just says: Failed to import.

If i look in the log files is was saying: (In XenCenter Console, push tab Help, and then clock on “View application log files. And then open op XenCenter.log):

System.Exception: Failed to import. —> System.IO.InvalidDataException: Failed to add resource Hard Disk Image. —> System.Exception: Failed to import. —> System.Exception: Failed to import virtual disk file. —> System.Xml.XmlException: Root element is missing.

Error on a Danish windows

System.Exception: Failed to import. —> System.IO.InvalidDataException: Failed to add resource Hard Disk Image. —> System.Exception: Failed to import. —> System.Exception: Failed to import virtual disk file. —> System.Xml.XmlException: Rod element mangler.

To fix this problem I did:
In XenCenter, select View -> Hidden Objects
This will show you hidden objects, such as Transfer objects.
Found the failed imported machine, right click on it and delete it.
Now you should found a XenServer Tranfer VM X.X.X-X, right click on it and delete it.

Now connect to the console on the XenServer host: (Master of the pool if you have such one)
And type this commands:

cd /opt/xensource/packages/files/transfer-vm
./install-transfer-vm.sh
