I'm probably treading old territory here, but what virtualization software is currently available that can support both Linux and Windows guests without svm or vmx on the host CPU? What I know of: - Virtualbox. Free, fills the bill, and works well enough; however, it's maintained by Oracle, which at this point is a problem. - Qemu/kQemu: branded obsolete and superseded by Qemu/KVM - and the latter does not support hardware without svm or vmx. I'm not sure kQemu even compiles with newer kernels. And that's it, AFAIK. Are there any competing products at all, that can handle a Pentium D CPU without VT-x? FOSS? Freeware? Payware? Anything? Or has everyone switched over to hardware-assisted virtualization?
