QEMU and macOS Big Sur
If you try to run QEMU
under macOS Big Mac Sur with the -machine accel=hvf flag (basically with Apple’s Hypervisor Framework
) you’ll get one ugly error; every time hv_vm_create() runs it returns an HV_ERROR. The reason is that the com.apple.vm.hypervisor entitlement (used in macOS 10.15) has been deprecated and replaced by com.apple.security.hypervisor.
You need to sign your binary with the correct entitlement. Add the XML below to an entitlements.xml file.
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN"
"http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>com.apple.security.hypervisor</key>
<true/>
</dict>
</plist>
After that, sign the QEMU binary with the entitlements.xml file.
$ codesign -s - --entitlements entitlements.xml --force /usr/local/bin/qemu-system-x86_64
Starting QEMU with -machine accel=hvf will work now.
Why Do We Assume Extraterrestrials Might Want to Visit Us?
It is presumptuous to assume that we are worthy of special attention from advanced species in the Milky Way. We may be a phenomenon as uninteresting to them as ants are to us; after all, when we’re walking down the sidewalk we rarely if ever examine every ant along our path.
Our sun formed at the tail end of the star formation history of the universe. Most stars are billions of years older than ours. So much older, in fact that many sunlike stars have already consumed their nuclear fuel and cooled off to a compact Earth-size remnant known as a white dwarf. We also learned recently that of order half of all sunlike stars host an Earth-size planet in their habitable zone, allowing for liquid water and for the chemistry of life.

Aldous Huxley interview
Aldous Huxley interviewed by Mike Wallace in 1958, Huxley shares his visions and fears for this brave new world: the difficulties and dangers of world overpopulation; the tendency towards distinctly hierarchical social organisation; the crucial importance of evaluating the use of technology in mass societies susceptible to persuasion; the tendency to promote modern politicians to a naive public as well-marketed commodities.
