Try it on your x64 host? Segfault!
Remove the static linking? It catches pure virtual call!

Useful read? https://stackoverflow.com/a/14082540

Result on arm64:

⚠️ Quickly put together in April 2023, you're reading a gist, not a community wiki. It's fundamentally hacky, heavily summarized, and might be out-of-date, make sure you're familiar with the concepts before attempting this!

So, for some reason, the arm64 images used in lxc don't run on amd64 qemu by default.

The images are hosted here: https://us.lxd.images.canonical.com/images/
We will go for an ubuntu jammy arm64 image: https://us.lxd.images.canonical.com/images/ubuntu/jammy/arm64/default/20230413_07:43/disk.qcow2
There are plenty to choose from, just make sure to pick the qcow2 file
If you have lxc you can also run: lxc image export images:ubuntu/jammy/arm64 --vm images_ubuntu_arm64

It's a good thing to make a backup of this file as we're going to change it right away.
