+1. How do I symbolicate kernel panic traces?
+
+Just add keepsyms=1 to either the Kernel Flags setting in /Library/Preferences/SystemConfiguration/com.apple.Boot.plist,
+or to the boot-args NVRAM variable. Reboot, and any subsequent panics will be automatically symbolicated. You can run
+mangled C++ symbols through the c++filt command line utility to get the proper C++ function signatures.

+$ sudo nvram boot-args="-v keepsyms=1"

+### Exposing AVX and AVX2 instructions to macOS
+
+Exposing AVX and AVX2 instructions to macOS requires support for these
+instructions on the host CPU.
+
+The `boot-clover.sh` script already exposes AVX and AVX2 instructions to the
+macOS guest by default. Modify or comment out the `MY_OPTIONS` line in
+`boot-clover.sh` file in case you are having problems.
+
+To enable AVX2, do the following change,
+
+`Clover boot menu -> Options -> Binaries patching -> Fake CPUID -> 0x0306C0  # for Haswell`
+
+For details, see [this wiki](https://clover-wiki.zetam.org/Configuration/KernelAndKextPatches) page.
+
+Once enabled, the following commands can be used to confirm the presence of AVX
+and AVX2 instructions on the macOS guest.
+
+```
+$ sysctl -a | grep avx
+hw.optional.avx2_0: 1
+hw.optional.avx1_0: 1
+
+$ sysctl -a | grep leaf7
+machdep.cpu.leaf7_features: SMEP BMI1 AVX2 BMI2
+machdep.cpu.leaf7_feature_bits: 424
+```
+
+### Using virtio-net-osx with macOS
+
+Configuration options for macOS Sierra (thanks to virtio-net-osx project users),
+
+```
+-netdev user,id=hub0port0 \
+-device virtio-net,netdev=hub0port0,id=eth0 \
+-set device.eth0.vectors=0
+```
+
+Adapt these to your use case. These changes need to be made in the `boot-*`
+scripts. On the guest, install the included `Virtio-Net-Driver-0.9.4.pkg`
+package.
