after waiting for UEFI-GOP and using bhyve (with vm-bhyve as a convenient tool) an a new E3-1225 v5 based system,
the following are my findings so far.
  Currently my rational for running bhyve is twofold:
- Run a Windows 8.1 or 10 instance for accessing different remote locations via different VPN solutions
  - Run Centos7/RHEL7 instances with SAP Systems on it

But first a huge Thanks to all who worked on bhyve and made it usable in its current state.
That alone is quite impressive.

What works so far:
- Windows 8, 8.1 and 10 installs and runs in graphical mode flawlessly.
- Centos7 installs and runs too using the UEFI-GOP Image (Yeah, no more Grub fiddling :-) - I was able to graphically Restore/Reconfigure a Acronis Windows-Backup into a Bhyve instance
  using the Acronis Restore-CD (Converting a BIOS Win8.1 to UEFI Win8.1)

What doesn't:
- Only vnclient from FreeBSD can connect to the bhyve VNC Server.
I havn't found any vncviewer running on Windows which where able to work (tried UltraVNC, RealVNC, ...) - in VNC only most basic Keys work most special characters like (*\@) (and of course no german localization)
  but at least a usual US-kbd would be helpful.
(Is there a way to debug the keystrokes or duplicate a localized VNC kbd from some VNC server) - For the SAP-Systems it seems that only 4 disks get used when the disk type is virtio-blk.
  (Is this intentionally or a feature of vm-bhyve? How to provide more disks)
- It seems to miss a way to add an ISO CD/DVD without booting from it automatically. Also ISO's seem to miss a hot-plug feature (f.e. for inserting driver CD's after installation.

Some additional questions:
- Can one over-provisioning/ballooning guest memory's ?
- Is it (speed-wise) better to use ZFS-zvol's or files in regular ZFS-directories?
- Are the virtio-blk or ahci-hd disks having the same overhead?
- Can ahci-hd be used paravirtualized in Centos?

Thanks in advance!

All in all it looks quite promising!
