[Qemu-devel] [PATCH v2 02/16] vl: add the vhost-pci-slave command line option |
Date: |
Fri, 12 May 2017 16:35:34 +0800 |
An example of the QEMU command to create a vhost-pci-slave is:
-chardev socket,id=slave1,server,wait=off,path=${PATH_SLAVE1}
-vhost-pci-slave socket,chardev=slave1
The master can connect to the slave as usual:
-chardev socket,id=sock2,path=${PATH_SLAVE1}
-netdev type=vhost-user,id=net2,chardev=sock2,vhostforce
-device virtio-net-pci,mac=52:54:00:00:00:02,netdev=net2
