Subject: [Qemu-devel] KVM emulation failure with recent kernel and QEMU Seabios
Date: Thu, 12 Mar 2015 09:09:31 +0100 [thread overview]
Message-ID: <550149BB.40501@siemens.com> (raw)
Hi,
apparently since the latest QEMU updates I'm getting this once in a
while:
KVM internal error. Suberror: 1

The command line to trigger it:
qemu-system-x86_64 -m 1G -enable-kvm -s -cpu kvm64 -smp 4 -no-kvm-irqchip
The issue did not yet show up when using in-kernel irqchips or when
doing "git checkout 11d39a13 pc-bios", i.e. reverting the recent BIOS
updates.
I'm on QEMU master (with 04f56432 reverted) and either kernel 4.0.0-rc3
or kvm.git next.
