https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D273372 --- Comment #9 from Mark McBride <mark@markmcb.com> --- More data (as of 14.0-RELEASE-p2) Bug still present. I reversed my testing to see how things would go with a VM-first approach. * I disabled all jails * I set SR-IOV on each of 2 NIC ports to 2 passthrough, 4 non-passthrough. Altogether, 12 VFs on 2 PFs. * I set the processor's iGPU device and 4 NIC passthrough VFs for passthrou= gh in /boot/loader.conf via pptdevs=3D * I started a Debian VM (gpu + VF) and FreeBSD VM (VF) using vm-bhyve Everything works fine. Both VMs start, I can see the GPU and setup networki= ng on the VFs in Debian. And networking is fine in FreeBSD. No issues after several hours. However, starting any jail using an SR-IOV VF will bring it all down. * I config jails.conf with 1 jail: vnet; vnet.interface =3D "cxlv0"; * I start the jail Almost immediately the Chelsio card fails. As usual, I can connect to the system via serial console and all seems well except networking is dead. In summary, I can create VMs, or I can create jails. The first will succeed, and the second will trigger failure. --=20 You are receiving this mail because: You are the assignee for the bug.=
