I opened this issue in a ovn scenario, but same issue in ml2-ovs 64 bytes from 10.46.228.38: icmp_seq=434 ttl=61 time=92.3 ms 64 bytes from 10.46.228.38: icmp_seq=435 ttl=61 time=97.6 ms 64 bytes from 10.46.228.38: icmp_seq=436 ttl=61 time=650 ms 64 bytes from 10.46.228.38: icmp_seq=437 ttl=61 time=650 ms 64 bytes from 10.46.228.38: icmp_seq=438 ttl=61 time=650 ms 64 bytes from 10.46.228.38: icmp_seq=439 ttl=61 time=177 ms 64 bytes from 10.46.228.38: icmp_seq=440 ttl=61 time=650 ms 64 bytes from 10.46.228.38: icmp_seq=441 ttl=61 time=649 ms 64 bytes from 10.46.228.38: icmp_seq=442 ttl=61 time=649 ms 64 bytes from 10.46.228.38: icmp_seq=443 ttl=61 time=650 ms 64 bytes from 10.46.228.38: icmp_seq=444 ttl=61 time=650 ms 64 bytes from 10.46.228.38: icmp_seq=445 ttl=61 time=90.9 ms 64 bytes from 10.46.228.38: icmp_seq=446 ttl=61 time=648 ms ping from vm to vm in a ml2-ovs scenario [cloud-user@tempest-testnfvoffload-server-995490205 ~]$ ping 30.30.220.199 PING 30.30.220.199 (30.30.220.199) 56(84) bytes of data. 64 bytes from 30.30.220.199: icmp_seq=1 ttl=64 time=3595 ms 64 bytes from 30.30.220.199: icmp_seq=2 ttl=64 time=2595 ms 64 bytes from 30.30.220.199: icmp_seq=3 ttl=64 time=1595 ms 64 bytes from 30.30.220.199: icmp_seq=4 ttl=64 time=595 ms 64 bytes from 30.30.220.199: icmp_seq=5 ttl=64 time=2424 ms 64 bytes from 30.30.220.199: icmp_seq=6 ttl=64 time=1425 ms 64 bytes from 30.30.220.199: icmp_seq=7 ttl=64 time=425 ms 64 bytes from 30.30.220.199: icmp_seq=8 ttl=64 time=1893 ms 64 bytes from 30.30.220.199: icmp_seq=9 ttl=64 time=894 ms 64 bytes from 30.30.220.199: icmp_seq=10 ttl=64 time=824 ms 64 bytes from 30.30.220.199: icmp_seq=11 ttl=64 time=894 ms 64 bytes from 30.30.220.199: icmp_seq=12 ttl=64 time=435 ms 64 bytes from 30.30.220.199: icmp_seq=13 ttl=64 time=873 ms 64 bytes from 30.30.220.199: icmp_seq=14 ttl=64 time=1895 ms 64 bytes from 30.30.220.199: icmp_seq=15 ttl=64 time=896 ms 64 bytes from 30.30.220.199: icmp_seq=16 ttl=64 time=2896 ms 64 bytes from 30.30.220.199: icmp_seq=17 ttl=64 time=1896 ms 64 bytes from 30.30.220.199: icmp_seq=18 ttl=64 time=896 ms The problem was caused by the guest vm which is a bit old (RHEL 7.6) When updating the vm guest to RHEL 9.2 I do not see the ping issue any more. |
