Hi,
@Yuvaraj: Thanks, I already read this article, and I am aware of memory overhead, but I thought it should at least be possible to reservate half of the host memory to a single VM with just one vCPU.
As I said, there is and will be only one VM on the host with a passthrough device attached, therefore it is necessary tp reservate all VM memory.
With 8GB RAM it is not possible to start the VM with more then 3GB reserved. That are just 3GB vor the VM and 5GB for ESXi and overhead.
When I added 2GB RAM to see how it behaves then it was also not possible to go beyond 4GB. So just 4GB for the Vm and 6GB for the ESXi and overhead.
