My main annoyances are: * It is slower (might not matter depending on your workload). * It requires manual tuning to set the correct RAM limit (whereas Docker containers on Linux are just normal processes so they just use however much RAM they need like any other process). * It's difficult to use the normal administration tools you're familiar with: you can't, from the host, see containers running in top, or attach a debugger to them. You have to either open a shell in the container and install all the typical GNU/Linux tools there, or have some weird remote debugging setup.
