Hi All,
Using the virt-manager/libvirtd/qemu-kvm stack (centos 6), is it
possible to leave a NIC "installed" but cause it to simulate that the
network cable is unplugged? Preferably this could be "hot"
plugged/unplugged but otherwise doing it cold.
Guest os is also centos 6, in case it matters (shouldn't).
Any pointers?
Thanks,
David Mansfield

Libvirt 0.9.5 added the ability to do <link state='down'/> for various
networks; I'm not sure if this has been backported to your version of
CentOS, or if you'll have to upgrade to something newer.
For more details on the addition:
