--- Comment #4 from [email protected] --- Created attachment 265143 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=265143&action=edit vtnet0 pcap during SCP test Hello Please find bellow the requested information * For reproducing the issue you copy a file from the VM to some other host? For the test you can copy a file from the VM to your PC. * Is the other host another VM running in parallel to the FreeBSD VM? Yes but their is plenty of resources available on the host. * Is the other host a physical host? Physical this one does not matter, I have the issue with a VM on the same host or using my PC as a client. * Are you running any sort of NAT/Firewall on the FreeBSD VM? Not in the FreeBSD VM and not on the path between the FreeBSD VM and the "client" * Could you provide the output of ifconfig vtnet0? # ifconfig vtnet0 vtnet0: flags=1008843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST,LOWER_UP> metric 0 mtu 1500 options=ec07b9<RXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4,TSO6,LRO,VLAN_HWTSO,LINKSTATE,RXCSUM_IPV6,TXCSUM_IPV6,HWSTATS> ether 92:93:c8:6e:95:77 inet 12.0.251.19 netmask 0xffff0000 broadcast 12.0.255.255 inet6 fe80::9093:c8ff:fe6e:9577%vtnet0 prefixlen 64 scopeid 0x2 media: Ethernet autoselect (10Gbase-T <full-duplex>) status: active nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL> * Could you provide the output of sysctl hw.vtnet # sysctl hw.vtnet hw.vtnet.lro_mbufq_depth: 0 hw.vtnet.lro_entry_count: 128 hw.vtnet.rx_process_limit: 1024 hw.vtnet.tso_maxlen: 65535 hw.vtnet.mq_max_pairs: 32 hw.vtnet.mq_disable: 0 hw.vtnet.lro_disable: 1 hw.vtnet.tso_disable: 0 hw.vtnet.fixup_needs_csum: 0 hw.vtnet.csum_disable: 0 * Could you provide the output of sysctl dev.vtnet.0 dev.vtnet.0.txq0.rescheduled: 0 dev.vtnet.0.txq0.tso: 0 dev.vtnet.0.txq0.csum: 0 dev.vtnet.0.txq0.omcasts: 2 dev.vtnet.0.txq0.obytes: 258 dev.vtnet.0.txq0.opackets: 3 dev.vtnet.0.rxq0.rescheduled: 0 dev.vtnet.0.rxq0.host_lro: 0 dev.vtnet.0.rxq0.csum_failed: 0 dev.vtnet.0.rxq0.csum: 0 dev.vtnet.0.rxq0.ierrors: 0 dev.vtnet.0.rxq0.iqdrops: 0 dev.vtnet.0.rxq0.ibytes: 82768 dev.vtnet.0.rxq0.ipackets: 948 dev.vtnet.0.tx_task_rescheduled: 0 dev.vtnet.0.tx_tso_offloaded: 0 dev.vtnet.0.tx_csum_offloaded: 0 dev.vtnet.0.tx_defrag_failed: 0 dev.vtnet.0.tx_defragged: 0 dev.vtnet.0.tx_tso_without_csum: 0 dev.vtnet.0.tx_tso_not_tcp: 0 dev.vtnet.0.tx_csum_proto_mismatch: 0 dev.vtnet.0.tx_csum_unknown_ethtype: 0 dev.vtnet.0.rx_task_rescheduled: 0 dev.vtnet.0.rx_csum_offloaded: 0 dev.vtnet.0.rx_csum_failed: 0 dev.vtnet.0.rx_csum_inaccessible_ipproto: 0 dev.vtnet.0.rx_csum_bad_offset: 0 dev.vtnet.0.rx_csum_bad_ipproto: 0 dev.vtnet.0.rx_csum_bad_ethtype: 0 dev.vtnet.0.rx_mergeable_failed: 0 dev.vtnet.0.rx_enq_replacement_failed: 0 dev.vtnet.0.rx_frame_too_large: 0 dev.vtnet.0.mbuf_alloc_failed: 0 dev.vtnet.0.act_vq_pairs: 1 dev.vtnet.0.req_vq_pairs: 1 dev.vtnet.0.max_vq_pairs: 1 dev.vtnet.0.%iommu: dev.vtnet.0.%parent: virtio_pci2 dev.vtnet.0.%pnpinfo: vendor=0x00001af4 device=0x1000 subvendor=0x1af4 device_type=0x00000001 dev.vtnet.0.%location: dev.vtnet.0.%driver: vtnet dev.vtnet.0.%desc: VirtIO Networking Adapter * Details of the step to generate the pcap : - I have create a 1G file "truncate -s 1G /tmp/1G.data" - start the pcap filtering on the IP of the vtnet0 - From my other "scp [email protected]:/tmp/1G.data /dev/null" - Few seconds later I stopped the scp and the pcap.
