我正在 QEmu 中运行虚拟机。来宾虚拟机中的以下命令
cat /proc/interrupts | egrep 'virtio.*(input|output)'给出以下输出：
26: 0 3376 0 0 0 0 0 0 PCI-MSI-edge virtio2-input
27: 0 1 0 0 0 0 0 0 PCI-MSI-edge virtio2-output
29: 0 3368 0 0 0 0 0 0 PCI-MSI-edge virtio3-input
30: 0 2 0 0 0 0 0 0 PCI-MSI-edge virtio3-output
32: 0 3490 0 0 0 0 0 0 PCI-MSI-edge virtio4-input

48: 0 0 1 0 0 0 0 0 PCI-MSI-edge virtio9-output
virtio2...virtio9好像是8块网卡。但是，我无法弄清楚其中哪一个对应于哪张卡。有没有办法获取 MAC 地址virtio3，或者以其他方式识别网卡？
答案1
我有一个方法（前几次在另一个论坛上采取过）
# vm mac address list
for vm in $(virsh list | grep running | awk '{print $2}'); do \
echo -n "$vm "; \
virsh dumpxml $vm| grep -oP "52:54:[\da-f:]+" ;
done > vm_mac.list
# vm ip list
arp -i virbr0 | grep '52:' | while read addr ; do \
ip=$(echo $addr | awk '{print $1}'); \
mac=$(echo $addr | awk '{print $3}'); \
vm=$(grep "$mac" vm_mac.list | awk '{print $1}'); \
echo "$vm $ip $mac"; \
done | sort
