Hello, we used Opennebula in a Singlenode/allinone - Setup and everything worked like a charm. Now we added another hypervisor and got a little problem. The connectivity to the vms on the new nodes is very laggy. There is a big issue with packetloss and I have no idea why. The vm-network ist configured with linuxbridge. Any idea where to look for the fault? Kind Regards ``` root@opennebula:/etc/one/vmm_exec# onevnet show 1 VIRTUAL NETWORK 1 INFORMATION ID : 1 NAME : Bridge USER : user GROUP : oneadmin LOCK : None CLUSTERS : 0 BRIDGE : brone VN_MAD : bridge PHYSICAL DEVICE : ens6f1 AUTOMATIC VLAN ID : NO AUTOMATIC OUTER VLAN ID : NO USED LEASES : 8 PERMISSIONS OWNER : um- GROUP : --- OTHER : --- VIRTUAL NETWORK TEMPLATE BRIDGE="brone" BRIDGE_CONF="stp=on" BRIDGE_TYPE="linux" DNS="192.168.33.5 192.168.33.9" GATEWAY="192.168.99.254" NETWORK_MASK="255.255.0.0" OUTER_VLAN_ID="" PHYDEV="ens6f1" SEARCH_DOMAIN="company.internal" SECURITY_GROUPS="0" VLAN_ID="" VN_MAD="bridge" ADDRESS RANGE POOL AR 0 SIZE : 24 LEASES : 8 RANGE FIRST LAST MAC 02:00:c0:a8:21:01 02:00:c0:a8:21:18 IP 192.168.33.1 192.168.33.24 LEASES AR OWNER MAC IP IP6 0 V:75 02:00:c0:a8:21:01 192.168.33.1 - 0 V:48 02:00:c0:a8:21:02 192.168.33.2 - 0 V:62 02:00:c0:a8:21:03 192.168.33.3 - 0 V:64 02:00:c0:a8:21:04 192.168.33.4 - 0 V:65 02:00:c0:a8:21:05 192.168.33.5 - 0 V:67 02:00:c0:a8:21:06 192.168.33.6 - 0 V:72 02:00:c0:a8:21:08 192.168.33.8 - 0 V:73 02:00:c0:a8:21:09 192.168.33.9 - root@opennebula1:/var/lib# brctl show bridge name bridge id STP enabled interfaces brone 8000.32621c203cfa yes ens6f1 one-64-0 root@opennebula:/etc/one/vmm_exec# brctl show bridge name bridge id STP enabled interfaces brone 8000.3ae5fb70dec0 yes ens6f1 one-48-0 one-62-0 one-65-0 one-67-0 one-73-0 one-75-0 brtwo 8000.38eaa792805c yes eno1 one-48-1 ``` ---

The problem was the Networkcard. Changed the hardware. Now everything is fine.
