Now you're getting insulting. It's normal for options to depend on other options. Sometimes they're directly nested (eg. E1000 depends on NETDEVICES, and it's nested under that option), sometimes they're not (eg. E1000 depends on PCI, which is selected elsewhere). The fact that you are only just realizing this is not Michael's problem. >> > Flip off everything in drivers -> virtio >> > >> > Now go to drivers -> block and try to turn on virtio-blk. >> > >> > It's not listed! >> >> Yes.

I get annoyed that menuconfig doesn't show options whose dependencies aren't possible, too. (I got bitten the other way: it doesn't show dependencies which can't be disabled, and I was trying to turn KALLSYMS off). But as I found out just last week, the '/' key allows you to find any option, and shows what dependencies it has, and their values. Hope that helps, Rusty. _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/virtualization
