Solution

1. Navigate to folder containing qemu binary (e.g. ~/Library/Android/sdk/emulator/qemu/darwin-x86_64)

2. Create file entitlements.xml with the following content:

   <?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>
   

3. Make sure you have XCode command line tools installed

   sudo xcode-select --install

4. Resign qemu binary:

   codesign -s - --entitlements entitlements.xml --force ./qemu-system-x86_64
