Thank you very much! I must again say sorry that I posted the whole thing as a one patch series, next time I'll post each series separately, and I also try to post the patches as soon as I write them. I didn't post them because I felt that the whole thing needs good testing and I only recently gotten to somewhat automate my nested migration tests which I usually use to test this kind of work. Best regards, Maxim Levitsky PS: the strict_mmu option does have quite an effect on nested migration with npt=0/ept=0. In my testing such migration crashes with pagefault in L2 kernel after around 50-100 iterations, while with this options, on survived ~1000 iterations and around the same on intel, and on both machines L1 eventually crashed with a page fault instead. Could be that it just throws timing off, or maybe we still do have some form of bug in shadow paging after all, maybe even 2 bugs. Hmmm.... I automated these tests so I can run them for days until I have more confidence in what is going on. Best regards, Maxim Levitsky > > Paolo >
This is set of various patches that are stuck in my patch queue. KVM_REQ_GET_NESTED_STATE_PAGES patch is mostly RFC, but it does seem to work for me. Read-only APIC ID is also somewhat RFC. Some of these patches are preparation for support for nested AVIC which I almost done developing, and will start testing very soon. Resend with cleaned up CCs.
