https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=242894 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 stack. 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 where 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 and 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 between 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. -- You are receiving this mail because: You are the assignee for the bug.
