If you’ve been playing with kvm for a while now you know what a hassle network configurations can be.

In previous posts you can find instructions on how to configure bridged networking when managing your kvm guests by command line.

By default kvm provides mechanisms to communicate with your host from within your guest machine when running your guest machine with userspace networking ie. –net user.

In the previous release of KVM-72, native support for VDE was added but you needed to explicitly enable it during compilation using the –enabe-vde flag.

Compiling the current release of vde2-2.2.2 gives compilation errors due to a missing macro variable in the code.

Beginning with KVM-72, you now have the option of using Virtual Distributed Ethernet (VDE) natively within KVM. This support was added as a result of the last merge with the qemu-svn tree.
