Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: kvm
Assignee: [email protected]

2 HDD
Using qemu-kvm and ovmf the following error occurs erratically when booted into a windows 10 host:
KVM: entry failed, hardware error 0x80000021
If you're running a guest on an Intel machine without unrestricted mode support, the failure can be most likely due to the guest entering an invalid state for Intel VT. For example, the guest maybe running in big real mode which is not supported on less recent Intel processors.

The error occurs whether or not pci devices are passed through to the host or not, and in every conceivable processor configuration that works for Windows guests.
The error occurs approximately 10 minutes into using the machine (give or take a few minutes).
Occasionally the error occurs on boot of the guest.
This has also happened on previous kernels.
Currently I have the kvm_intel module loaded with emulate_invalid_guest_state=0, although it also occurs in the same capacity if the parameter is set to 1.
Please feel free to contact me for additional information.

Please look for the VMCS dump in /var/log/messages or dmesg and paste it here. Thanks!

It's the same bug. The patch has not yet hit Linus's tree, you need to apply it manually.

--- Comment #7 from Joe Knockenhauer <[email protected]> --- Very strange, I applied it to the latest mainline and got the same issue. It is entirely possible I am doing something wrong. I apologize if I wasted your time, I'll try again on an LTS kernel and see if I can get it working.
Sorry about that. Thanks!
