New: nVMX: L1 crashes with no-kvm-irqchip
https://bugzilla.kernel.org/show_bug.cgi?id=53651
Summary: nVMX: L1 crashes with no-kvm-irqchip
Product: Virtualization
Version: unspecified
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: kvm
AssignedTo: [email protected]
ReportedBy: [email protected]
Regression: No
Steffen Evers reported that "We are using qemu-kvm with nested virtualisation (two guest levels). The 1st-level guest sporadicly crashes on start-up of 2nd level guest (in BIOS). We have now found out that it always crashes with parameter "no-kvm-irqchip" set.".
The L1 crash is because of "KVM: entry failed, hardware error 0x80000021".

I didn't try to verify this myself.

--- Comment #1 from Jan Kiszka <[email protected]> ---
Steffen once did these tests for me. They were done on a now very old software stack, I no longer remember the precise details nor could I reproduce the same scenario. I can just confirm that I'm running nested with -no-kvm-irqchip regularly on a - granted - more modern host without problems. Therefore, I would suggest to close this issue.
