What is the difference between LXC and KVM?

KVM fully emulates a complete Linux PC, with all networking and, frequently, with a fixed/owned IPv4 and/or IPv6.

LXC containers mostly emulate a complete Linux PC, sharing the underlying kernel and its RAM and, therefore, demanding substantially less resources. On C-Servers, in order to obtain the lowest possible price, they do not have a direct IPv4 (merely an internal IPv4 that has an external IPv4 NAT with 10 allowed ports, and an IPv6 on a /80 subnet), and they use the base kernel of the system, which for the FocusLXC offer, per Virtualizor supported operating systems, is RHEL 8.9's kernel 4.18.0, with backporting from 5.x kernels.

These LXC systems are especially tailored for long-running, non-demanding functions, and they are our lowest price.

Technically-speaking, our FocusLXC-288 VPS is equivalent to the NanoVPS-384 VPS because those 288MB RAM do not include the kernel + systemd RAM consumption.
