Have done so for many years. No apparent issues. Although I run only
"sandbox" VM, I have not struck one that would not install & run

The "details" view of the virtual machine configuration has a field for
CPU model. I leave it at the default of Opteron G3, although my CPU is
only a dual core Athlon. I've not noticed any issues from this
configuration.
On that basis, you could select "CPU" architecture for the VM to suit
the most likely host and probably change it later too.
