"kvm" accelerator not found. On x86, when kvm module is removed, there are a bunch of other warnings: Could not access KVM kernel module: No such file or directory failed to initialize KVM: No such file or directory Back to tcg accelerator.

I couldn't find out if we can assume kvm_has_gsi_routing() is true everywhere, or just on a few architectures.

Other architectures don't matter, what counts is that we can require kvm_has_gsi_routing() == true on x86. Paolo

I'm in the mood for deleting some code today.
Unfortunately my remark on this patch was only for the irq0 override thing, which is x86-specific. I think other architectures still need userspace irqchip in some cases.

Use kvm acceleration if available. Signed-off-by: Marcel Apfelbaum <marcel@redhat.com> --- Hi, It saves a few seconds so we'll be able to add more tests. I cc-ed Paolo to get his opinion on the correct way to look for the kvm support.
