SR-IOV Support
planned
Zachary Smith
Customers would like to have the ability to request a server with SR-IOV enabled, either as a option to toggle on reboot or for a new installation.

There are some examples and use cases in CNCF's CNF Testbed and the Network Service Mesh (NSM) project that we would like to use in the Equinox Metal (EM) provided CNCF community. Having a way to programmatically select nodes with SR-IOV enabled will make it easier for development+testing as well as letting other folks try those examples in EM w/o using reserved instances.

I second this request. It would be incredibly useful to simply have SRIOV available without having to jump through hoops with reserve instances. This is doubly true when wanting to provide 'kick the tire' instructions to potential adopters...

yeah, and this should be somehow knwon to the meta data so thats i.e. k8s deployments like sr-iov operator can interact with that
Adam Rothschild
is there any downside to just enabling this on all supporting cards (as opposed to a toggle)? might be our easiest option...

Adam Rothschild: In our experience it should not hurt a long you not slice the NIC it is just as normal. But I have not seen 100s of cases yet ;-)
