There is also separate issue that VirtualBox CPU doesn't support fma, f16c. e.g.: root@qemux86-64:~# mediaindexer Incompatible processor. This Qt build requires the following features: fma f16c
There is 7 years old enhancement ticket for Virtualbox without any progress: https://www.virtualbox.org/ticket/15471 People who use VirtualBox to run qemux86-64 builds, should consider changing DEFAULTTUNE.
