The linkstate setting of an <interface> is only meant to change the online status reported to the guest system by the emulated network device driver in qemu, but when support for auto-creating tap devices for <interface type='ethernet'> was added in commit 9717d6, a chunk of code was also added to qemuDomainChangeNetLinkState() that sets the online status of the tap device (i.e. the *host* side of the interface) for type='ethernet'. This was never done for tap devices used in type='bridge' or type='network' interfaces, nor was it done in the past for tap devices created by external scripts for type='ethernet', so we shouldn't be doing it now. This patch removes the bit of code in qemuDomainChangeNetLinkState() that modifies online status of the tap device.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
