Hi, I am trying to get started with vm-bhyve and getting a little stuck. I am sure there are things I don't understand here so I hope you will bear with me. I am using a machine with an AMD FX-8370E eight-core CPU, running 12.2-RELEASE-p4. The machine boots from a ~60GB SATA SSD which is configured as the zroot zpool. I have run a few bhyve vms on this machine before, including a couple of linux variants, by just using the bhyve command directly and they worked fine. In those cases, I just used files created with truncate(1) for vm disks but I would like to use zvols. vm-bhyve looks pretty nice to me and I think I'd like using it also. I have this in /boot/loader.conf: vmm_load="YES" nmdm_load="YES" if_tap_load="YES" if_bridge_load="YES" and this in /etc/rc.conf: vm_enable="YES" vm_dir="zfs:zroot/vmm" vm_list="" vm_delay="5" And so I thus have this: [root@sand] # zfs list -r zroot/vmm NAME USED AVAIL REFER MOUNTPOINT zroot/vmm 1.43G 36.8G 1.43G /vmm and this: [root@sand] # vm datastore list NAME TYPE PATH ZFS DATASET default zfs /vmm zroot/vmm I have populated /vmm/.templates with the files from /usr/local/share/examples/vm-bhyve but made some changes to them. For example, the freebsd-zvol.conf template now looks like this: loader="bhyveload" cpu=1 memory=4096M network0_type="virtio-net" network0_switch="public" disk0_dev="sparse-zvol" disk0_name="disk0" I've also populated /vmm/.iso with some ISO images including FreeBSD-12.2-RELEASE-amd64-disc1.iso. So with that, I can for example do this: [root@sand] # vm create -t freebsd-zvol fbsd1 [root@sand] # vm list NAME DATASTORE LOADER CPU MEMORY VNC AUTOSTART STATE fbsd1 default bhyveload 1 4096M - No Stopped and zfs things then look like this: [root@sand] # zfs list -r zroot/vmm NAME USED AVAIL REFER MOUNTPOINT zroot/vmm 1.43G 36.8G 1.43G /vmm zroot/vmm/fbsd1 164K 36.8G 108K /vmm/fbsd1 zroot/vmm/fbsd1/disk0 56K 36.8G 56K - So that all seems pretty good so far. Then I do this: vm install -f fbsd1 FreeBSD-12.2-RELEASE-amd64-disc1.iso The vm boots and I'm asked to choose a console type, I take the default vt100, and boom -- I get the familiar FreeBSD Installer screen. I proceed through that and try to do a Guided Root-on-ZFS installation, but when I choose Pool Type/Disks, I'm told "No disk(s) present to configure." So. Pretty clearly doing something wrong here but I'm not sure what. Happy to provide any further info that I might have neglected above. Any advice that points me in the right direction much appreciated. Thanks.
