Test Case 1: test_perf_virtio_one_vm_dpdk_fwd_vhost-cuse_jumboframe
====================================================================
On host:
1. Start up vhost-switch, mergeable 1 means the jubmo frame feature is enabled.
vm2vm 0 means only one vm without vm to vm communication::
taskset -c 1-3 <dpdk_folder>/examples/vhost/build/vhost-switch -c 0xf -n 4
--huge-dir /mnt/huge --socket-mem 1024,1024 -- -p 1 --mergeable 1 --zero-copy 0
--vm2vm 0
2. Start VM with vhost cuse as backend::
taskset -c 4-6 /home/qxu10/qemu-2.2.0/x86_64-softmmu/qemu-system-x86_64
-object memory-backend-file, id=mem,size=2048M,mem-path=/mnt/huge,share=on
-numa node,memdev=mem -mem-prealloc \
-enable-kvm -m 2048 -smp 4 -cpu host -name dpdk1-vm1 \
-drive file=/home/img/dpdk1-vm1.img \
-netdev tap,id=vhost3,ifname=tap_vhost3,vhost=on,script=no \
-device virtio-net
pci,netdev=vhost3,mac=52:54:00:00:00:01,id=net3,csum=off,gso=off,guest_csum=off,guest_tso4=off,guest_tso6=off,guest_ecn=off
\
-netdev tap,id=vhost4,ifname=tap_vhost4,vhost=on,script=no \
-device
virtio-net-pci,netdev=vhost4,mac=52:54:00:00:00:02,id=net4,csum=off,gso=off,guest_csum=off,guest_tso4=off,guest_tso6=off,guest_ecn=off
\
-netdev tap,id=ipvm1,ifname=tap3,script=/etc/qemu-ifup -device
rtl8139,netdev=ipvm1,id=net0,mac=00:00:00:00:00:01 \
-localtime -nographic
On guest:
3. ensure the dpdk folder copied to the guest with the same config file and
build process as host. Then bind 2 virtio devices to igb_uio and start testpmd,
below is the step for reference::
./<dpdk_folder>/tools/dpdk_nic_bind.py --bind igb_uio 00:03.0 00:04.0
./<dpdk_folder>/x86_64-native-linuxapp-gcc/app/test-pmd/testpmd -c f -n 4
-- -i --txqflags 0x0f00 --max-pkt-len 9000
$ >set fwd mac
$ >start tx_first
4. After typing start tx_first in testpmd, user can see there would be 2 virtio
device with MAC and vlan id registered in vhost-user, the log would be shown in
host's vhost-sample output.
5. Send traffic(30second) to virtio1 and virtio2, and set the packet size from
64 to 1518 as well as the jumbo frame 3000. Check the performance in Mpps. The
traffic sent to virtio1 should have the DEST MAC of Virtio1's MAC, Vlan id of
Virtio1. The traffic sent to virtio2 should have the DEST MAC of Virtio2's MAC,
Vlan id of Virtio2. As to the functionality criteria, The received rate should
not be zero. As to the performance criteria, need check it with developer or
design doc/PRD.
Test Case 7: test_perf_virtio_one_vm_dpdk_fwd_vhost-user_jumboframe
====================================================================
This case is similar to TestCase1, just change the backend from vhost cuse to
vhost-user, so need rebuild the dpdk in vhost-user on host, other steps are
same as TestCase1. The command to launch vm is different, see below as
example::
<qemu-2.2.0_folder>/x86_64-softmmu/qemu-system-x86_64 -name us-vhost-vm1
-cpu host -enable-kvm -m 2048 -object
memory-backend-file,id=mem,size=2048M,mem-path=/mnt/huge,share=on -numa
node,memdev=mem -mem-prealloc -smp 2 -drive file=/home/img/dpdk1-vm1.img
-chardev socket,id=char0,path=<dpdk/vhost-net -netdev
type=vhost-user,id=mynet1,chardev=char0,vhostforce -device
virtio-net-pci,mac=52:54:00:00:00:01,netdev=mynet1 -chardev
socket,id=char1,path=/home/qxu10/dpdk/vhost-net -netdev
type=vhost-user,id=mynet2,chardev=char1,vhostforce -device
virtio-net-pci,mac=52:54:00:00:00:02,netdev=mynet2 -netdev
tap,id=ipvm1,ifname=tap3,script=/etc/qemu-ifup -device
rtl8139,netdev=ipvm1,id=net0,mac=00:00:00:00:00:09 -nographic
On the guest, need add one parameter at the end of testpmd command line:
--disable-hw-vlan-filter.
Rerun the case and make sure no vhost-register issue.
Thanks
Qian

Subject: [PATCH v2 0/3] Fix vhost startup issue
The patch set fix vhost sample fails to start up in second time:
It should call api to unregister vhost driver when sample exit/quit, then the
socket file will be removed(by calling unlink), and thus make vhost sample work
correctly in second time startup.
It also adds/refines some log information.
Changchun Ouyang (3):
vhost: add log when failing to bind a socket
vhost: fix the comments and log
vhost: call api to unregister vhost driver
