Re: [Qemu-devel] First shot at adding IPMI to qemu

It would be great if you could add a basic testcase using qtest, even if only for the internal interface, to ensure it doesn't bitrot. Paolo

I'll work on these over the next few days and resubmit. Thanks. It would be great if you could add a basic testcase using qtest, even if only for the internal interface, to ensure it doesn't bitrot. Yes, certainly. Thanks again, -corey
