I was able to make the trace shorter by grepping only what's happening on a single CPU core (#0): https://www.dropbox.com/s/slbxmxyg74wh9hv/l1mmio-cpu0.txt.gz?dl=0 It was taken with kernel 3.16.1 modules with your paging-tmpl.h patch applied. This time, the trace looks somewhat different, however my code still hangs in nested KVM (and doesn't on real HW). Thanks, Valentine
