Ooops sorry !
Thank you for your help. What I tried since your last message :
This my startup configuration (VMs halted) :
-----
killall ovsdb-server
killall ovs-vswitchd
for tap in `seq 0 3`; do ip tuntap del mode tap sw0p$tap; done;
rmmod openvswitch
modprobe openvswitch
for tap in `seq 0 3`; do ip tuntap add mode tap sw0p$tap; done;
for tap in `seq 0 3`; do ip link set sw0p$tap up; done;
rm -f /etc/openvswitch/conf.db
ovsdb-tool create /etc/openvswitch/conf.db
/usr/share/openvswitch/vswitch.ovsschema
mkdir /var/run/openvswitch
ovsdb-server --remote=punix:/var/run/openvswitch/db.sock --pidfile --detach
ovs-vsctl --no-wait init
ovs-vswitchd --pidfile --detach
ovs-vsctl add-br sw0
ovs-vsctl add-port sw0 sw0p2
ovs-vsctl add-bond sw0 bond0 sw0p0 sw0p1
ovs-vsctl set port bond0 bond_mode=balance-tcp
ovs-vsctl set port bond0 lacp=active
ovs-vsctl set port bond0 other_config:lacp-time=fast
----
Then I launch the 2 VMS (Windows 10.0.0.1 with LACP Intel proprietary
driver configured with 802.3ad and a simple Linux Debian guest 10.0.0.2)
When the Windows guest is on, I get on the host :
# ovs-appctl bond/show bond0
bond_mode: balance-tcp
bond-hash-algorithm: balance-tcp
bond-hash-basis: 0
updelay: 0 ms
downdelay: 0 ms
next rebalance: 5899 ms
lacp_negotiated: true
slave sw0p1: enabled
active slave
may_enable: true
slave sw0p0: enabled
may_enable: true
From now, it is really confusing. From the Linux vm, I ping the Win VM,
the first 8 pings are OK and then it stops (without any intervention).
What Wireshark says under Windows :
- bonded NIC : ICMP requests from Linux and Win ARP requests
- first NIC : only Win ARP requests (+LACP announces)
- second NIC : only ICMP requests from Linux (+LACP announces)
What tcpdump says under Linux :
- Win ARP Requests
- Linux ARP Replies
- ICMP Requests
Linux ARP replies never reach the Win VM.
Bond state on the host :
# ovs-appctl bond/show bond0
bond_mode: balance-tcp
bond-hash-algorithm: balance-tcp
bond-hash-basis: 0
updelay: 0 ms
downdelay: 0 ms
next rebalance: 8452 ms
lacp_negotiated: true
slave sw0p1: enabled
active slave
may_enable: true
hash 237: 0 kB load
slave sw0p0: enabled
may_enable: true
hash 80: 1 kB load
