dom0-system-display-network to show the status of all network interfaces.

Ifconfig –a to display list ofnetwork interfaces and their current status.

xm network –list 12345 to get the list of virtual interfaces attached to the guest.

esxlist –v 12345 to list all the network interfaces attached to the guest.

Each physical NIC is mapped to one or more virtual networks, each of which is assigned a Xen bridge.

One Xen bridge will be created for each physical NIC.

All physical NICs are mapped to a single Xen bridge.

No mapping of physical NICs to Xen bridges is done by default.

The first physicalNIC is assigned to dom0's management; a Xen bridge is then created for each of the remaining cards.

xm list -1 will show all of the network interfaces for all of the virtual machines, which can be used to see which bridge is having problems.

config_network.py -l will show which network interfaces are in use, and which are having problems.

brctl show will show the status of each bridge, and which VIFs are connected to it. This canthen be used to determine which bridge is having problems.

System-config-network will list the virtual interfaces, which can be inspected to see which are having problems.

ifconfig -a will show a list of all network interfaces and their current status, which will help determine which bridge is having problems.
