Jan, Yunhong, I was just thinking about xen-unstable:20892, which exposes real current max_mfn to guests, so that they can more accurately clamp their m2p address translations. I was wondering whether this changeset is actually a bad idea in light of memory hot-add, as now implemented by Yunhong? I would imagine this can mean that max_mfn is now dynamic, and can increase in value after boot. So would 20892 thus leave all existing guests (e.g., dom0!) broken after a hot-add which adds new highest RAM addresses? -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
