This bug was found when handling Bug 1601355. Additional info(continued): 4. When there is no packets flow, the issue is gone. Everything works well. vhost-user + vIOMMU + guest virtio-net kernel driver, but no packets flow in guest. works. This issue has gone with latest rhel8.4-av. VM keeps working well after many rebooting. Versions: qemu-img-5.2.0-4.module+el8.4.0+9676+589043b9.x86_64. 4.18.0-278.rt7.43.el8.dt4.x86_64 tuned-2.15.0-1.el8.noarch libvirt-7.0.0-3.module+el8.4.0+9709+a99efd61.x86_64 python3-libvirt-6.10.0-1.module+el8.4.0+8948+a39b3f3a.x86_64 openvswitch2.13-2.13.0-86.el8fdp.x86_64 dpdk-20.11-1.el8.x86_64 So I would close this bz as "CURRENTRELEASE". Feel free to let me know if any concerns. Thanks. |
