I installed a pro-trial version of Rstudio server on the VM.
As a result, the license expiration message is being printed out.
When checking the var/log/message, the following message was output.
May 18 11:05:13 SkI-bipapp1 license - manager  : ERROR Error logging a trial : (17)
Licensing failed because this program is running inside a virtual machine.
Evaluation inside a virtual machine requires either access or an offline evaluation key.
Please contact RStudio customer support to cover or activate on this virtual machine ;
LO GGED FROM : int inttudio::activation:ActivationContext:reportError
(const std::string &, HRESULT) / rootshtudio-protocmsserveractivationContext 92.
What should I do?
