Greetings - I have been using bhyve for a while to host a FreeBSD stable/9 client. It works pretty well, but I often get messages similar to this, after a kick off a full 'buildworld' on the virtual host: calcru: runtime went backwards from 8023812124499416 usec to 1365567459 usec for pid 34794 (make) calcru: runtime went backwards from 8023812124499416 usec to 1365055948 usec for pid 34794 (make) I have the following in my /boot/loader.conf on the virtual host: zfs_load="YES" vfs.root.mountfrom="zfs:zroot2" virtio_load="YES" virtio_pci_load="YES" virtio_blk_load="YES" if_vtnet_load="YES" autoboot_delay="3" kern.hz="100" vfs.zfs.prefetch_disable="0" dtraceall_load="YES" (I have a small UFS partition that I mount as /bootdir, and /boot is symlinked into that. So, the virtual machine loads the kernel off of UFS, but everything else is ZFS on the machine.) Any suggestions for eliminating this warning? -Kurt (dmesg of host machine follows) Copyright (c) 1992-2013 The FreeBSD Project.
