That was KVM for AArch32. AArch64 support was merged in 3.11 IIRC. But I wouldn't want to run anything based on this indeed.

Fernando: if you're eager to try KVM on this system, mainline might be a much better option (assuming you don't need any of the fancy stuff). Thanks, M. -- Jazz is not dead. It just smells funny... _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
