[SOLVED] q35 vs i440fx

[oah433]

Hi
I am trying to understand when should I choose the machine-type to "Q35 vs i440fx", I understand that Q35 supports PCIe so I can do GPU passthrough but what about the i440fx, is the Q35 is that superior why do we still have it?
For my setup where I have bunch of VMs running apache + MySQL on some and Nginx +MongoDB on the others which machine type should I use and does it really matter?
Thx

i'd say for "most" vms it does not really matter, since nearly all of the functionality of the chipset/platform is virtual anyway. if you need some features from a newer platform (like pcie) i'd choose q35, but
else there is not much reason to choose it over i440fx

that makes much sense. thx a ton

In real practice, why are there 2 options?
to better understand if possible

because I usually use "Machine: q35" for vms where my Processor is : host" does that make sense?

In real practice, why are there 2 options?

as i said, e.g. sometimes a device passthrough needs to be passed through as 'pcie express' device which is only available on q35

because I usually use "Machine: q35" for vms where my Processor is : host" does that make sense?

for this the machine type should not make any difference
