Physical and VM installation of QlikView server follow the same basic steps, but with a VM there are some additional VM specific settings to consider for performance.
A Qlik partner could guide/perform this for/with you and I can recommend one if needed.
Otherwise there are guides available which will help you:
Qlikview server reference manual – with help in general and also shows the installation steps
QlikView_and_Server_Virtualization_White_Paper – will detail some settings for VM installations, the main one being to give the QlikView server dedicated resources (CPU and RAM), disable memory ballooning & disable NUMA in the bios.
These and other documents can be found in the resource library on the community.
