This topic provides troubleshooting tips for when the virtual machine does not start when attempting to perform an Install Capture.
Unable to prepare the virtual machine for use. Could not authenticate session. Check your access credentials and try again.
This error means that the username and password that Install Capture uses to log on to XenServer are invalid. Typically this means that the password has expired. The username and password are stored in the virtual machine configuration in encrypted form.
To correct this error, use the Virtual Machine Configuration Wizard to edit the virtual machine configuration and enter the new password. Make sure you save your changes. Then start the Install Capture again.
AppDNA is unable to revert the virtual machine to the selected snapshot. This is because the user account provided for accessing XenServer is not authorized to perform the operation.
This error means that the user account that Install Capture uses to log on to XenServer does not have the permissions required to revert the virtual machine. The username and password are stored in the virtual machine configuration in encrypted form.
The solution to this problem is to arrange for your XenServer user account to have the necessary permissions. Typically, you need the "VM power admin" role).
If you are using a vSphere or Hyper-V virtual machine, AppDNA attempts to open it in a Remote Desktop Connection window. This can fail in certain circumstances, such as when the AppDNA machine is joined to a domain but the virtual machine is not or the reverse. When this happens, configuring the hosts file on the AppDNA machine with the address of the guest OS can sometimes resolve the issue. The hosts file is a local file that Windows uses to map host names to IP addresses so that it can identify machines on the network.
To find out whether these steps are relevant:
To configure the hosts file on the AppDNA machine:
