VT-x, VT-d confuse

hi everyone!

Spend a lot of time in here, try to google, still confused.I have some plans to buy a budget system for me to run virtual box so i can start my microsoft labing , but there is one thing that confusing me at the moment. To be able to run VM's on PC as I understood the mobo or BIOS (not sure

) has to support VT-d, and the CPU has to support VT-x ???? whats the difference between those two in simple words?

I am choosing the following 2 systems:

Compare Intel® Products

both chipset has VT-d, but no VT-x

can someone put some light on this issue, cause the last thing I want to do is put money on system that will not run VM

??:

VT-x is the actual hardware virtualisation assistance - absolute necessary, whereas VT-d allows you direct passthrough of devices, such as PCI devices, not essential in PC environments but nice to have when running server (vSphere server where you need RAID cards passed through directly to the guest etc.).

So - VT-x = must, VT-d = nice to have

Oh and to answer the question lol - VT-x is a CPU architecture so those CPU you posted are fine. As a result you won't find it on the motherboard while PCI passthrough is something the motherboard has to support too - hence the mentioning of VT-d on the chipset.

Just make sure it is all enabled in the bios - which isn't necessarily the case by default .. Execute Disable Bit is another thing to enable for virtualization in the bios.
