2022-06-30 00:11:00 【高桐@BILL】
本节描述了viotio-net 虚拟设备的配置以在Hypervisor host中通过网络驱动建立Guest与Host之间的通信。
下图描述了guest中的virtio-net 虚拟设备与Hypervisor Host中的 devnp-vdevpeer-net.so io-pkt-*驱动的点对点连接。

一、配置virtio-net虚拟设备
下面的部分展示了托管Guest的VM的*.qvmconf文件中的virtio-net虚拟设备:
system qnx71-arm-guest ... # The loc and intr gic options are for ARM only. The guest will see the # virtio-net vdev as a memory-mapped I/O device at the specified location. vdev virtio-net loc 0x1c0c0000 intr gic:40 mac aa:aa:aa:aa:aa:aa name p2p peer /dev/vdevpeers/vp0 peerfeats 0x3
qnx71-arm-guest
表示Guest的VM的系统名称(参考system option), 同样会定义在vdevpeer-net peer 选项中倒是第二个令牌 (peer=/dev/qvm/qnx71-arm-guest</
