So I found (and could verify) that it is actually this change from 3.10 which fixes nested for L1 guests >=3.15:
commit 33fb20c39e98b90813b5ab2d9a0d6faa6300caca Author: Jan Kiszka <[email protected]> Date: Wed Mar 6 15:44:03 2013 +0100 KVM: nVMX: Fix content of MSR_IA32_VMX_ENTRY/EXIT_CTLS And that change looks not too intrusive and to be rather a fix than adding any feature. It also cleanly cherry-picks into 3.2. ** Also affects: linux (Ubuntu Precise) Importance: Undecided Status: New ** Changed in: linux (Ubuntu Precise) Status: New => Confirmed ** Changed in: linux (Ubuntu Precise) Importance: Undecided => High ** Changed in: linux (Ubuntu Precise) Assignee: (unassigned) => Stefan Bader (smb) ** Changed in: linux (Ubuntu Utopic) Status: Confirmed => Invalid ** Changed in: linux (Ubuntu Vivid) Status: Confirmed => Invalid ** Changed in: linux (Ubuntu Utopic) Assignee: Stefan Bader (smb) => (unassigned) ** Changed in: linux (Ubuntu Vivid) Assignee: Stefan Bader (smb) => (unassigned) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1431473 Title: kvm_intel (nested) module will not load [Input/output error] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1431473/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
