Is it possible to detect if my MacOS app is running on a virtual machine? (I don't mean the simulator, just some VM like VirtualBox or anything else..)

I only have VMWare but the techniques I used can be extended to VirtualBox. Besides below simple techniques, each VM vendor has an interface to talk to host system. However they may require higher privileges.
VMware
- VMWare Tools If VMWare Tools is installed, you may check following files.
GFX card
You can check whether VmTools is installed. Particulary the presence of VMwareGfx.kext inside /Library/Extensions folder
VMware Tools Daemon Launcher
/Library/LaunchDaemons/com.vmware.launchd.vmware-tools-userd
VMware Tools Daemon
/Library/Application Support/VMware Tools/vmware-tools-daemon
You can also check if there is VMware Graphics card present by checking IORegistry
Since VMware GFX has following
Device ID: 0x0405 Revision ID: 0x0000 Vendor ID: 0x15ad
- Model Identifier
You can get all information about device with
system_profiler
For example system_profiler SPHardwareDataType gives following information
Hardware Overview:
Model Name: Apple device
Model Identifier: VMware7,1
Processor Speed: 3.23 GHz
Number of Processors: 2
Total Number of Cores: 2
L2 Cache (per Processor): 256 KB
L3 Cache (per Processor): 6 MB
Memory: 2 GB
Boot ROM Version: VMW71.00V.0.B64.1507021939
SMC Version (system): 2.8f0
Serial Number (system): VMiZVX4JH1rt
Hardware UUID: 564D8995-57E0-91F5-AEDF-1968AB31F81E
Model Identifier and Boot ROM can be used to find out VMware
system_profiler SPHardwareDataType | awk '/Model Identifier/ {print $3}'
