https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D242894 Bug ID: 242894 Summary: [bhyve] - issue with TCP/IP stack between 12.0-RELASE (guest) and 12.1-RELEASE (hypervisor) Product: Base System Version: 12.0-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bhyve Assignee: virtualization@FreeBSD.org Reporter: arkadiusz.majewski@iptrace.pl Hello, I've got an issue with TCP/IP network connection (including ICMP). I suppose there is something wrong between hypervisor and guest network sta= ck. Hypervisor: bhyve on FreeBSD 12.1-RELEASE just upgraded Guest: FreeBSD 12.0-RELEASE before upgrade Hypervisor: bridge and tap for guest Guest: vtnet virtual netowrk card So, I was trying tu upgrade guest to 12.1-RELEASE. After a few attempts whe= re I was losing SSH connection, I saw there is an issue with network connection. Deep investigation gave me the information, that after some time of network traffic I was disconnected from network on TCP/IP stack, both bridge, tap a= nd vtnet network cards were enabled and active. Then after some minutes traffic went well. I was trying to download bigger file from Internet (100 MB), after 5 MB of downloading I lost network connection. I have others 12.1-RELEASES and they work. I upgraded them before upgraded hypervisor. So, when hypervisor was as 12.0-RELEASE I hadn't got an issue. I tried another guest (12.0-RELEASE) and the problem is the same. To be more precise about my architecture, between hypervisor and that guest= is another guest called firewall, it means the firewall pass the traffic betwe= en Internet and not upgraded guest yet I have an issue. The firewall (guest) is already upgraded to 12.1-RELEASE. Of course, I upgraded that guest before upgraded hypervisor. --=20 You are receiving this mail because: You are the assignee for the bug.=
