sometimes we hoped that the memory of vm can be evenly distributed in all nodes according to interleave mode. But different hosts has different node number. So we add nodeset='all' for interleave mode.

Anyway, back to the cpuset/nodeset presentation. If today it's "A,C,E" or "A-E,^B,^D", then why not devise a way to use "0,~0" meaning 0 and the one's complement of 0 (e.g. everything else). That way if I wanted to, I could "0,~0,^4" meaning everything except 4. Of course the downside is that I need to know what the guest maximum is. The only way to know that is in post parse processing. So doing this may involve moving the translation of @nodeset and @cpuset...
Adding ~0 will break applications parsing the attribute in the same way "all" will, as they will reject '~' as an invalid value.
