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?
