Moving VMs Between Different Hosts

Hey all,

I normally use the host CPU option when setting up VMs (for best performance). This has worked great for me so far. I have recently setup another host server and set them up in a cluster. The new host has different hardware to the previous servers, so now I have Intel and AMD processors depending on which host is used. If VMs might be moved between these different hosts (with different hardware), is it dangerous (or not advisable) to use the host CPU option? If so, which CPU do you guys recommend using?

Hope my question makes sense…
TIA

Hi,
there is no official support for live-migrating between hosts with CPUs from different vendors and I'm afraid it's mostly luck-based and very specific to the concrete setup/CPUs. I'd simply try out different configurations with test VMs to see if any work reliably.
