[Bug 1045027] Re: iPXE kills kvm with KVM: entry failed, hardware error 0x80000021
As both the error message and the commit message refer to "big real mode" I tried a locally build 3.5.3 kernel with commit "KVM: VMX: Fix KVM_SET_SREGS with big real mode segments" reverted. With an unmodified local build 3.5.3 I could reproduce the original error. With the local build 3.5.3 with the reverted commit the vm boots fine. It passes pxe and boots successfully from cdrom (server beta1 iso). Also the installed server boots fine with the revert. NB: I left the module parameters at their default values, so especially emulate_invalid_guest_state=n for this test. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1045027 Title: iPXE kills kvm with KVM: entry failed, hardware error 0x8021 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1045027/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Albert: Still on 3.5.0-13, if I use the emulate_invalid_guest_state=y it does survive the iPXE boot, although if I leave it to fall through iPXE to the DVD boot it fails differently below.

[Bug 1045027] Re: iPXE kills kvm with KVM: entry failed, hardware error 0x80000021
I am seeing this same error message when I start kvm with an empty disk attached right when pxe kicks in. With kernel v3.6-rc3 it works fine, with v3.5.3it still fails. I found a comment from the upstream developer at http://www.mail-archive.com/kvm@vger.kernel.org/msg73419.html: "We'll try to get emulate_invalid_guest_state=1 to be the default for 3.6." 3.6-rc3 indeed has emulate_invalid_guest_state enabled, with 3.5.3 and 3.5.0-13-generic it is disabled (as shown with cat /sys/module/kvm_intel/parameters/emulate_invalid_guest_state). Unloading kvm_intel and reloading it with emulate_invalid_guest_state=y gives me a working kvm again, not crashing when pxe kicks in. Dave, could you test if setting emulate_invalid_guest_state=y solves the issue for you too? (sudo rmmod kvm_intel and sudo modprobe kvm-intel emulate_invalid_guest_state=y) If that works for Dave as well, I guess the winning upstream commit is "KVM: VMX: Emulate invalid guest state by default" (a27685c33a on main tree from kernel.org). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1045027 Title: iPXE kills kvm with KVM: entry failed, hardware error 0x8021 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1045027/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thanks, Tim. Can folks first test the following two kernels instead of the one's mentioned in comment #7? v3.5.2: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5.2-quantal/ v3.5.3: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5.3-quantal/ I can then build some test kernels if we find that the bug is fixed in v3.5.3. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1045027 Title: iPXE kills kvm with KVM: entry failed, hardware error 0x8021 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1045027/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Joe - The big difference from 3.5.0-12 to 3.5.0-13 is the rebase from stable v3.5.2 to v3.5.3.

I'd like to perform a "Reverse" bisect to identify the commit that fixed this bug in v3.6-rc4. Would it be possible for folks affected by this bug to assist in the reverse bisect by testing some kernels? If so, we first need to identify which release candidate in v3.6 introduced the fix. If you can reproduce this bug, it would be great if you can test the following kernels and report back the first release candidate that fixes the bug: v3.6-rc1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6-rc1-quantal/ v3.6-rc2: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6-rc2-quantal/ v3.6-rc3: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6-rc3-quantal/ You will need to install both the linux-image and linux-image-extra .deb packages. There no need to test all of those kernels, just up until you find the first one that does not have the bug.

I picked this up when trying to run iscsi tests for beta-1 quantal reverting to the previous kernel version fixed this problem.
