https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=273372 --- Comment #15 from Mark McBride <mark@markmcb.com> --- (In reply to Mark Linimon from comment #12) I still see problems in 15.1-RC1. If it works fine for others, I'm guessing it's something specific to the processor or motherboard (Supermicro X12STH-F with Xeon E-2324G). The general case remains true: jails OR bhyve using VFs = success jails AND bhyve using VFs = fail No issues on the same platform with Linux VMs and LXD side-by-side, so I know the system is capable. No issues if I do everything with a bridge. It's specific to the combination of passthrough and non-passthrough VFs in use at the same time. I don't think heat is the issue either. Temps look normal. And as noted, when I use only jails or only VMs, the VFs work just fine. Issue exists with Intel, Chelsio, and Mellenox cards, though the precise failure symptoms vary with each (and for this iteration I only tried with Intel and Chelsio). -- You are receiving this mail because: You are the assignee for the bug.home | help
