VirtualBox: boot from USB image
Projects like OPNsense.org provide you with an .img file that you would dd to a USB device to boot from. This is not obvious how to use from VirtualBox. You need to convert that into a VMDK file. Basically, the command I used was: vboxmanage convertfromraw OPNsense-19.7-OpenSSL-serial-amd64.img /tank/VMs/4544-opnsense-19-freebsd/opensense-19.7-usb.vmdk –format vmdk Then attach that VMDK file…

That last one escaped me but is necessary because you need it when you do a dkms install. So after updating that stuff, I was able to dkms install…
Speeding ahead with ZFS and VirtualBox | FreedomPenguin
I have created a lot of VMs with VirtualBox and I organize their snapshotting with ZFS.
Raw ZVOL access in ZFS on Linux not an option for VirtualBox?
I have gotten about as far as I can go…I can boot a Fedora netinstall cd, and I can attempt to fdisk /dev/sda, but this device will not open in fdisk. This might be consistent with no “rdsk” device in the dev tree. Funny though, I can fdisk /dev/zd0, and it lists partitions. Could this…
Converting Virtualbox disk to ZFS volumes
I am trying to create zvol backed virtualbox guests using ZFS on Linux. Hopefully this is not too ambitious. Find size of original .VDI disk image: vboxmanage showhdinfo Fedora19.vdi Pass that file size into zfs create: zfs create -V40960M tank/VMs/Fedora19 Convert .vdi file to raw, best if you can do this from one hd to…
