[Lxc-users] How much LXC is secure?

Last year I've read many times, that LXC have some outstanding security issues, and are the encapsulation is not tight enough to prevent hijacking the host, when the guest is compromised. But I never managed to find out, how exactly does one escape the LXC container. I'm using the LXC

In general, I've found that LXC networking is no different than any other type of virtualizaion. In fact, If you implement libvirt, the virtual networking objects (ie br, virbr, etc) once created can be utilized by any/all virtual networking technologies. So, for example I also have KVM

Thank you for the reply. I may be not clear in the original question. For example, in KVM, the system setup a virtual network device pair in host, and added on end to bridge. So when an program is using the other end, its communication will be bridged to actual hardware. And KVM exposes a virtual
