Re: [CentOS-virt] Need info on vnet mapping to guests

Is there a better way to determine which vnet is connected to which guest?

You can put ``virsh domname <domid>'' or just ``virsh list'' with some awk into an snmpd exec script to enumerate the vifs with their domain names.

Also, does the mapping change when I stop and start guests or reboot the host?

Domain IDs do change between guest reboots so you will have to key your graphs with the domain name and not the vif name.
