Enable user to create vdpasim net simulate devices.
Show vdpa management device that supports creating, deleting vdpa devices.
$ vdpa mgmtdev show
vdpasim_net:
supported_classes
net
$ vdpa mgmtdev show -jp
{
"show": {
"vdpasim_net": {
"supported_classes": {
"net"
}
}
}
Create a vdpa device of type networking named as "foo2" from
the management device vdpasim:
$ vdpa dev add mgmtdev vdpasim_net name foo2
Show the newly created vdpa device by its name:
$ vdpa dev show foo2
foo2: type network mgmtdev vdpasim_net vendor_id 0 max_vqs 2 max_vq_size 256
$ vdpa dev show foo2 -jp
{
"dev": {
"foo2": {
"type": "network",
"mgmtdev": "vdpasim_net",
"vendor_id": 0,
"max_vqs": 2,
"max_vq_size": 256
}
}
}
Delete the vdpa device after its use:
$ vdpa dev del foo2
