Hi,
I am using ovs 2.5.0 + dpdk2.2.0 + libvirt1.2.18.1(qemu 2.3.1)
I have added 1 physical dpdk port and 1 vhostuser ports.
Following is my bridge:
Bridge "br0"
Port "dpdk0"
Interface "dpdk0"
type: dpdk
Port "vhost-user1"
Interface "vhost-user1"
type: dpdkvhostuser
Port "br0"
Interface "br0"
type: internal
the libvirt related setting as below
<domain type='kvm'>
...
<memory unit='KiB'>10485760</memory>
<currentMemory unit='KiB'>10485760</currentMemory>
<memoryBacking>
<hugepages>
<page size='1048576' unit='KiB' nodeset='0'/>
</hugepages>
</memoryBacking>
...
<cpu mode='host-passthrough'>
<topology sockets='1' cores='8' threads='2'/>
<numa>
<cell id='0' cpus='0-1' memory='10485760' unit='KiB' memAccess='shared'/>
</numa>
</cpu>
...
<interface type='vhostuser'>
<mac address='52:00:00:00:00:01'/>
<source type='unix' path='/usr/localvar/run/openvswitch/vhost-user1'
mode='client'/>
<model type='virtio'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x03'
function='0x0'/>
</interface>
...
/domain>
However, after I started the guest host, I found the guest host can send
packets to local host but cannot received packets from local host.
#ovs-ofctl dump-ports br0
OFPST_PORT reply (xid=0x2): 3 ports
port LOCAL: rx pkts=32, bytes=1536, drop=0, errs=0, frame=0, over=0, crc=0
tx pkts=13974, bytes=6983918, drop=882, errs=0, coll=0
port 1: rx pkts=15478, bytes=7120292, drop=0, errs=0, frame=?, over=?, crc=?
tx pkts=44, bytes=2928, drop=0, errs=0, coll=?
port 2: rx pkts=37, bytes=1866, drop=?, errs=0, frame=?, over=?, crc=?
tx pkts=0, bytes=0, drop=13969, errs=?, coll=?
Observe the vhost-user1 port (port 2), we can see all the Tx packets has been
dropped
The related syslog as below , it seems that the Tx queue mapping failed. Are
there some wrong with my POC?
