That's another way (and makes more sense). I just wanted to shorten the "Tristate" since it's not a tristate anyway. Should I count it as an ACK for s/virSwitch/virOnOff/ and s/virBool/virYesNo/ ? Martin

I prepended the "mem" so that it is visible that it has something to do with the memory, not the whole node. But I'm OK with pushing shared= as well. Using access= seems too ambiguously worded to me, although if most of you agree... Martin

Is there any possibility of that option having another value (in the future)? Otherwise shared= seems more appropriate to me. Let's see what others think, so I can finally get rid of this problem :) Martin

I prefer the approach of having values reflect the usage, as 'shared' vs 'private' for the value is clearer than 'on' vs 'off' IMHO.

OK, it makes more sense when you put it like that. I'll send a v2 to make sure everyone agrees on all three patches. Martin
