Thanks, this is very interesting. I am read to read it all, but I really would like you to expand some more on the motivation for this work. Productising this would be quite a bit of work. Spending just 6 lines on motivation seems somewhat disproportionate. In particular, do you have any specific efficiency measurements or estimates that you can share? -- MST _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/virtualization
