I outlined process here: https://bugs.freebsd.org/ https://dubaicallgirlsinuae.com/ Which in summary: 1. Use new VirtIO update provide by your patch 2. Disable VirtIO network from dev/virtio and modules/virtio 3. Apply netmap updates, but extend scope of condition compilation in sys/dev/netmap/if_ptnet.c to as per this snippet: <> ... #include #ifdef WITH_PTNETMAP #include #ifndef INET #error "INET not defined, cannot support offloadings" #endif ... <> 4. Remove vtnet driver from sys/amd64/conf/GENERIC & virtio network from sys/conf/files 5. Ensure you have right QEMU Q35 machine version. There is a caveat. This build works on with Q35 v 3.1 not 4.0. From: virsh dumpxml <> ... hvm ... <> So VirtIO is seeing some difference in behaviour. So that for: - Q35-3.1 you get VirtIO Storage - Q35-4.0 you do not get VirtIO Storage Matts has also been seeing variation in netmap networking cross QEMU 3.1 and QEMU 4.1, so this machine variation across release is likely related: https://bugs.freebsd.org/ https://dubaiescortsgirls.me/ Likely as per MattS case this is new bug and explains why people are getting different testing results. Cheers, John Hartley. ---------------------------------- I've also run into similar issues which I thought was a disk adapter handli= ng problem in freeBSD+Q35 because I ran into freeNAS not handling all of the disks, then say it didn't pick up the other disk adapters Until I tried again with freeBSD 11.3 and 12.0 with more adapters and it di= dnt pick up the network adapter. Realised when I read this, it is more of adapter namespace exhaustion. I'll upload some dmesg from previous tries. Unfortunately I couldnt save the recent dmesg output. --=20 You are receiving this mail because: You are the assignee for the bug.=
