We love OrbStack too! Thank you for it,
I wanted to make its VM/machine our default secure agent sandbox, but I couldn’t figure out how to isolate this VM from the host properly. This thread prompted me to find the issue though, and I saw this was recently implemented! https://github.com/orbstack/orbstack/issues/169
Yep! Still refining it but isolated machines now have fine-grained settings for filesystem mounts, network isolation, SSH agent forwarding, and CPU/memory/disk limits
