We recently upgraded our Mac to Big Sur 11.3, but since then, we have kept receiving mysterious crashes anytime we operate emulated equipment. The error states like this qemu-system-x86_64: failed to initialize HAX: Operation not supported by device in Big Sur. Without further delay, let’s begin solving this error.

Why does the “qemu-system-x86_64: failed to initialize HAX: Operation not supported by device in Big Sur” error occur?

We recently upgraded the Mac into Big Sur 11.3, and since then, anytime we attempt to activate emulated equipment, it has been mysteriously crashing on macOS. Also, when we went to launch the emulator using the Terminal, we received the following error message.

How To Fix The Error?

You may get around the problem until the Search engine addresses emulator code registration with the revised entitlements by obtaining the entitlement yourself. Create a new file entitled entitlements.xml with the given information.

The Specific Solution

Entitlements are vital pairs that allow an executable to utilize a service. Under this scenario, the QEMU binary cannot construct and maintain virtual machines. So, you must include the entitlement in the binary.

First, establish an XML file called entitlements.xml with the following information.

<?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>

Then, apply this command.

codesign -s - --entitlements entitlements.xml --force /usr/local/bin/qemu-system-x86_64

Whenever you receive the problem, open the terminal in a directory that contains the qemu-system-x86_64 package.

Next, right-click on the darwin-x86 64 directory and select New Terminal Window at Folder from the menu that appears. Remember to place your entitlements.xml documents in the darwin-x86 64 directory. Finally, execute the command at the terminal.
