[Tails-dev] Good news wrt. nested virtualization
Hi, FWIW, Intel Haswell architecture adds features (Shadow VMCS, nEPT) that, when using a recent enough qemu/kvm, make nested virtualization actually usable to run our test suite. Works fine for me :) Details: https://github.com/kashyapc/nvmx-haswell/blob/master/SETUP-nVMX.rst The bad news is that one needs a super-recent Intel CPU to take advantage of this. Others will still need to either run the test suite directly on their usual system, or to get a dedicated machine to run it.

Works fine for me :) we're also experimenting with nested virtualization. For what I could see, it basically works, but actually I have not done extensive testings, nor I managed to setup tails unit tests inside a virtual machine. The bad news is that one needs a super-recent Intel CPU to take advantage of this. Others will still need to either run the test suite directly on their usual system, or to get a dedicated machine to run it. I think there's room for colaboration at a hardware level, then ;) We have one of those. -- boyska gpg --recv-keys 0x58289ca9 ___ Tails-dev mailing list Tails-dev@boum.org https://mailman.boum.org/listinfo/tails-dev To unsubscribe from this list, send an empty email to tails-dev-unsubscr...@boum.org.

For what I could see, it basically works, FYI, our past experience (with pre-Haswell CPUs) was so painful (read: super-slow) that we've given up.

Great :) Note that in a few months, we'll have a server dedicated to running our test suite, so the advantage of using your box instead will vanish. Also, for people doing any kind of intensive Tails development, IMO being able to run the test suite locally is waaay more practical.
