Comment 2 for bug 1623871

I think this is a bug in Nova as the arch specific versions are hard coded and aarch64 is ignored in that. We just need to add the check for aarch64 also. So instead of a BP, it'll be good to fix it as a bug. The minimum version of libvert(1.2.7) and QEMU(2.1.0) which are verified for x86 also hold good for aarch64. Please let me know if I can proceed with fixing it as a bug.
