           Summary: hardware error 0x80000021 on a KVM virtual machine
                    with kernel 3.7
           Product: Virtualization
           Version: unspecified
    Kernel Version: 3.7.2
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1

        AssignedTo: [email protected]
        ReportedBy: [email protected]
        Regression: No

Hello,
I faced yesterday the hardware error 0x80000021 which was, I think allready
fixed: https://bugzilla.redhat.com/show_bug.cgi?id=854983

I use a Debian unstable system with a debianized vanilla kernel 3.7.2 (took that kernel from kernel.org and created a debian-package with make-kpkg) My host system is (as I sayed) a debian i686 on a thinkbook x60s with a Intel Core Duo CPU L2400 @ 1.66GHz. One of the first processors with vt, I think. My guest system is a debian-x86 testing as well. I tried to install debian virtual-machine with a net-install-iso-image, but right after the start of the cd it seems to pause (with virt-manager as frontend).

The error dump I got in /var/log/libvirt/qemu/Debian0.log:

KVM: entry failed, hardware error 0x80000021

this problem first occurs only with my custom-kernel. I tested it with the debian-trunk-kernel 3.7 on experimental as well, with the same result!

--- Comment #1 from [email protected] 2013-01-29 23:35:46 --- 32bit hosts don't get a lot of testing these days. I'd suggest you find the last kernel version that does work and then do a git bisect to figure out where it broke. In the mean time someone will try to find a way to reproduce. Let us know the outcome of your testing.

--- Comment #3 from George <[email protected]> 2013-03-25 12:43:55 --- I ran into this issue after upgrading the kernel from 3.5.7 to 3.6.11. Booting 32 bit Windows XP or Debian 6.0.5 on a older Dell D820 laptop (Family:
6 Model: 14 Stepping: 8 T2500 CPU) both failed with the hardware error.

Setting "options kvm_intel emulate_invalid_guest_state=0" in /etc/modprobe.d/kvm_intel.conf appears to have resolved the issue for me.

Hi, Gleb, I think your patch "KVM: VMX: mark unusable segment as nonpresent" has already fixed this problem. Your patch was accepted in main kernel in around 3.11, and he was using linux kernel 3.7, so understandably he would face this problem. Right? If so, we can close this ticket, he was just using some obsolete kernel in which we know the bug exists. (In reply to Gleb from comment #2)
