Я пытаюсь создать конфигурацию из 2 ВМ, расположенных на одном гипервизоре, к каждой ВМ я прикрепил интерфейс virtIO из гипервизора, отредактировав XML-файл каждой ВМ. Я создал ВМ и получил эти интерфейсы после присоединения:
ens7: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

Каждый интерфейс для каждой виртуальной машины. При отправке пинга с одной виртуальной машины на другую по IP-адресу я получаю сообщение: «Узел назначения недоступен», но при отправке пинга на одну виртуальную машину и запускеtcpdump -nei ens7 с другой стороны, я получаю сообщения:
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on ens7, link-type EN10MB (Ethernet), capture size 262144 bytes

Почему команда ping не работает, пока tcpdump распознает пакеты? Я отредактировал XML таким образом, чтобы выделить hugepages и ovs были правильными на гипервизоре.
