Meta question: What is the best upstream list for discussing ARM & KVM
issues? Or ARM & virt issues in general?
I'm trying to get stock qemu from git or qemu 1.6 to boot a guest using KVM.
My host has a 3.11.0 LPAE kernel, and it exposes a /dev/kvm device.
qemu can open this device, it gets as far as creating a KVM guest, and
that is all apparently successful. But the ioctl KVM_RUN returns -ENXIO.
ENXIO is not a documented return from the KVM_RUN API but I've looked
at the kernel code and I can't see where KVM_RUN would return ENXIO.
All places in general where ENXIO might be returned are related to the
function "irqchip_in_kernel" and the mysterious "VGIC" hardware (which
I guess is doing interrupt routing like APIC on PCs?)
Do I have to add one of these devices to the emulation perhaps?
Does anyone have a qemu command line which reliably boots a guest using KVM?
Rich.
