Virtlet tapmanger
controls the setup of VM networking using CNI
that is started by the virtlet command, since tapmanger
uses
the same virtlet
binary.
The Virtlet tapmanger
process has the following functionality:
vmwrapper
by sending the file descriptor over
a Unix domain socket to vmwrapper
. As a result, this file descriptor
can be used in another mount namespace of a container. And you do not need
a shared access to the directory containing network namespaces.
