Preparing the Host The first step to creating a virtual machine in bhyve is configuring the host system. First, load the bhyve kernel module: # kldload vmm Then, create a tap interface for the network device in the virtual machine to attach to. In order for the network device to participate in the network, also create a bridge interface containing the tap interface and the physical interface as members. In this example, the physical interface is em0 : # ifconfig tap0 create # sysctl net.link.tap.up_on_open=1 net.link.tap.up_on_open: 0 -> 1 # ifconfig bridge0 create # ifconfig bridge0 addm em0 addm tap0 # ifconfig bridge0 up   Creating a Debian Linux Guest with ZFS Using ZFS volumes instead of disk image files can provide significant performance benefits for the guest VMs. A ZFS volume can be created by:   # zfs create -V88G -o volmode=dev zroot/debiandisk0   List ZFS volume disk image files: % zfs list   Destroy A ZFS volume disk image file: #   zfs des...

When you start Debian Linux after you installed Debian with UEFI bhyve on FreeBSD and rebooted FreeBSD, you will get the error message as follows: BdsDex: failed to load Boot0001 "UEFI BHYVE SATA DISK BHYVE-OABE-20A5-E582" from PciRoot(0x0)/Pci (0x2, 0x0)/Stat(0x0,0xFFFF,0x0) : Not Found   Description It will try other way to start system, but it will failed finally. At the last, it will come to UEFI  Shell . How to access the Debian Guest VM? 1. Enter exit get out of the UEFI Shell (you will come to BHYVE panel) 2. Choose Boot Maintenance Manager 3. (In the Boot Maintenace Manager ) Choose Boot From File 4. (In File Explorer) NO VOLUME LABEL, [PciRoot(0x0)/ Pci()]  press Enter 5. (Still in the File Explorer) Choose <EFI> 6. (Still in the File Explorer) Choose debian   7. (Still in the File Explorer) Choose grubx64.efi 8. Then you will get into the system How can you fix it: 1) Get access inside your Debian Guest VM. 2) as root: cd /boot/efi/ 3) mkdir -p...

Preparing for the Installation Download  Ubuntu Server 20.04.3 LTS In order to boot Linux systems, grub2-bhyve must be first installed as follows: # pkg install grub2-bhyve     3. Creating a Linux Guest A ZFS volume can be created by: # zfs create -V16G -o volmode=dev zroot/linuxdisk0 Create a device.map that grub will use to map the virtual device to the files on the host system: (hd0)  /dev/zvol/zroot/linuxdisk0 (...
