LXC relies on the host machine's kernel and operating system to function. Because of this, some functionality is limited, such as:
- Using Windows and other operating systems.
- Installing new kernels.
- Changing kernel sys values.
There are also benefits to using LXC:
- May be better performing then KVM as there is no hypervisor overhead.
- Lower cost. Because the overhead is lower, the overall cost to host the containers is lower than KVM. We pass those cost savings to our customers.
