VIMAGE is a virtualization framework on top of FreeBSD jails + that was introduced to the kernel about eight years ago with + the vnet virtualized network stack.

+ +

Over the last few years, many people started to use VIMAGE + in production, production-like setups, and appliances. This + adoption increased the urgency to finish the work to avoid + panics on network stack teardown and to avoid memory + leaks.

+ +

The vnet teardown has been changed to be from top to + bottom, trying to tear down layer by layer. This is + preferable to removing interfaces first and then cleaning + everything up, as no more packets could flow. Along with this + work, various parts with potential memory leaks were plugged. + Lastly, vnet support was added to formerly + unvirtualized components, such as the pf and + ipfilter firewalls and some virtual interfaces.

+ + + The FreeBSD Foundation + + + Please test FreeBSD 11.0-ALPHA6 or later. When reporting + a problem, use the vimage keyword in the FreeBSD bug + tracker. + +
