bhyve server 2016 lockup

[Matt Churchyard]

Thanks for the replies guys. I've increased memory and switched to virtio-net. Been running for an hour or two so far. Windows just complains about the boot device if I try to move to virtio-blk.
I might set up another test using different settings during installation and see how that goes.

Only really played about with bhyve so far but starting to consider using for production machines, so any hard lockup is a bit of a worry.

Regards,
Matt

I've used specifically these drivers https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/archive-virtio/virtio-win-0.1.96/virtio-win-0.1.96.iso and had trouble with both later and earlier drivers, YMMV, and I sadly forget where I got this advice.
