Hello Everyone, I'm forwarding this as this bug affects use of KVM on newer Dell machines. The issue itself is described in rhbz#571991
There's a patch ready for libvirt. Without it everytime a TAP device is attached or detached from a network bridge (i.e. whenever any vm is started, stopped or restarted). The bridge-interface will lose network connectivity because it changes its MAC. This usually means that your ssh/xdmcp/whatever session to the host will break whenever you start or stop a VM. Maybe someone at Dell is willing to push Red Hat to fix it. We were hit by that issue on all our new R710 boxes and currently run an in-house built of libvirt to work around it. Regards, Andreas Rogge -------- Original-Nachricht -------- Betreff: [Bug 616517] libvirt should not use the MAC address assigned to tap devices/vnet interfaces by the TAP/TUN driver.
