I've been using TightVNC on Windows (first free client I came across) since GOP support came out and have not had any problems with it. > - 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. It's not clear whether you're saying that those special character have a problem or not? I'm in the UK and these keys seem to work fine in the VNC client I'm using. > (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) I know that the UEFI firmware only connects slots 3/4/5/6, but I don't know if some guests can support non-boot disks on other slots. In my bhyve manager I used to limit Windows to 3 disks (+1 cd), however I have tested 8 disks in Server2012 with a FreeBSD 12 host, which allows up to 32 disks per ahci controller. >- 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. I've just tried adding a bootable CD to bhyve as a second device and yes, it does appear to try and boot from it even though the hdd is bootable. I'm sure I've seen a UEFI cli at some point but I don't know if there's any way to configure boot order (devs?) Obviously hot-plug CD would be nice and I expect is a feature that would come eventually once the basics are finished. >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? These are probably all questions for the devs...
