proxmox cluster on different hardware

[spark 5]

hi, on question on top

we plan to use proxmox and ceph with one of our customer.

there are 2 amd server and 2 intel. we also plan to buy 3 new nodes, also intel.

could there be problems, running proxmox kvm (windows, linux) on both hardware platforms?
cpu should be default kvm(64).

thanks for answer,
ronny

Hi,

Running VMs on both hardware is itself not an issue.

Live migrating between nodes with different CPU manufacture may be problematic, but can work, depends on a lot of things so best way is to test it out in your specific setup

If you use special flags like pcid/spctrl ... this may also pose a problem with intra-cpu-manufacture live migration (e.g. new intel CPU has flag, older one not).
