Depends on where the software is looking to gather the info. KVM, Oracle VM and other hypervisors have "predictable" hardware combinations that are often
"QEMU Virtual CPU" or similar under KVM, 'cat /proc/cpuinfo
"VirtualBox Graphics Adapter" under VirtualBox, 'lspci'
The PCI IDs will also be a giveaway.
This kind of fingerprinting may be hard to avoid, as these strings are defined in the driver.
