I did a quick analysis if the flag (doublecheck might be needed). All systems which WORK CORRECTLY has these guest flags: x2apic vnmi ept
Systems which fail don't have any of these flags. x2apic -- improves guest performance by reducing the overhead of APIC access, which is used to program timers and for issuing inter-processor interrupts vnmi -- Intel Virtual NMI feature which helps with certain sorts of interrupt events in guests ept -- Intel Extended Page Table -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
