Hi, 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. (BTW: 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! Greetings --- Mike Gruß --- Michael Reifenberger
