Date: Sat, 20 Feb 2016 09:09:32 +0100	[thread overview]
Message-ID: <56C81F3C.4010006@web.de> (raw)

Hi all,

I suppose 5120901a37 introduced this: qemu with kernel_irqchip=off now
generates these warnings, one per VCPU, during QEMU startup. Is the plan
to live with them until we finally have x2APIC emulation in userspace
(ie. also MSR vmexiting to there), or should we otherwise avoid it?

Thanks,
Jan
