VMware still works great for older operating systems. I've had nothing but trouble with Hyper-V and VirtualBox lately.
It's sad because VirtualBox used to work okay but the legacy AMD NIC and SoundBlaster drivers have been bitrotting in the last few years and Hyper-V's predecessor Virtual PC used to be great with older OSes too.
If you prefer free software KVM/virt-manager works just fine as well there's just a bit more fiddling with options to make things happy.
