Hi Poul-Henning, > With the host now running: > > FreeBSD 11.0-CURRENT #0 r297514M > > And (another) i386 guest running: > > FreeBSD 11.0-CURRENT #3 r297721M > > I do not see the problem. > > I'm going to try the 10.1/i386 guest over the weekend. I've not yet been able to reproduce this. I've tried 2- and 3-vCPU 10.1/i386 guests on an Intel E3-1220 v3 (single and dual virtio-blk disks), and a 2 vCPU guest on an AMD Sempron 3850 APU. Buildworlds with -j set to the number of vCPUs have completed fine. The Intel system was using file-backed images on ZFS, while the AMD system was on UFS. The guests were UFS. The console was to stdout in a tmux session that was mostly backgrounded. Was there anything particular with your buildworld ? (-j settings, etc) Also, if the guest looks like it hangs, you can extract the RIPs with bhyvectl --get-rip --cpu=0 --vm=<vmname> bhyvectl --get-rip --cpu=1 --vm=<vmname> This might give a hint as to where the guest is spinning. later, Peter.
