Create a windows image from an ISO on SmartOS/bhyve

Create an ISO from this repo, and upload to a node. Use your favourite ISO creation tool, If you're using genisoimage the command is. Lets assume you're uploading to /zones/stuff on the node

genisoimage -o ../windows-virtio.iso -J -R -m .git -m README.md .

Download an ISO from your Visual Studio subscription onto a node to /zones/stuff

Look here - https://my.visualstudio.com/Downloads

Run

export WINDOWS_INSTALL_CD=/zones/stuff/<windows-iso>
export WINDOWS_DRIVER_CD=/zones/stuff/windows-virtio.iso

Then create a zone to run the VM in

zfs create -V 80G zones/windows

Then create a VM

pfexec /usr/sbin/bhyve -c 2 -m 3G -H \
    -l com1,stdio \
    -l bootrom,/usr/share/bhyve/uefi-rom.bin \
    -s 2,ahci-cd,$WINDOWS_INSTALL_CD \
    -s 3,virtio-blk,/dev/zvol/rdsk/zones/windows \
    -s 4,ahci-cd,$WINDOWS_DRIVER_CD \
    -s 31,lpc \
    -s 28,fbuf,vga=off,tcp=0.0.0.0:5900,w=1024,h=768,wait \
    -s 29,xhci,tablet \
    windows

The instance will wait until VNC is connectes, ssh into the node with a tunnel, and then connect your VNC

ssh -L 5555:localhost:5900 <node>

NOTE: You need to be prepared to quickly press a key when prompted on VNC once the instance starts in order for the Windows ISO to boot.

Now wait until bhyve terminates, which will take some time.

When bhyve terminates, run it again, but without the WINDOWS_INSTALL_CD line:

pfexec /usr/sbin/bhyve -c 2 -m 3G -H \
    -l com1,stdio \
    -l bootrom,/usr/share/bhyve/uefi-rom.bin \
    -s 3,virtio-blk,/dev/zvol/rdsk/zones/windows \
    -s 4,ahci-cd,$WINDOWS_DRIVER_CD \
    -s 31,lpc \
    -s 28,fbuf,vga=off,tcp=0.0.0.0:5900,w=1024,h=768,wait \
    -s 29,xhci,tablet \
    windows

And wait for bhyve to terminate again. It will take a while, but not as long as the first phase.

We're now ready to create the image:

zfs send zones/windows > /zones/stuff/windows.zvol
gzip /zones/stuff/windows.zvol
zfs destroy zones/windows
/usr/sbin/bhyvectl --destroy --vm=windows

Create an image manifest

{
    "v": 2,
    "uuid": "<new-uuid>",
    "name": "windows-<version>",
    "owner": "<admin-uuid>",
    "version": "1.0.0",
    "state": "active",
    "disabled": false,
    "public": true,
    "type": "zvol",
    "os": "windows",
    "files": [ {
        "sha1": "<files.sha1>",
        "size": <files.size>,
        "compression": "gzip"
    } ],
    "requirements": {
        "networks": [ {
            "name": "net0",
            "description": "public"
        } ],
        "ssh_key": true
    },
    "generate_passwords": "true",
    "users": [ {
      "name": "administrator"
    } ],
    "image_size": "<image-size>",
    "disk_driver": "virtio",
    "nic_driver": "virtio",
    "cpu_type": "host"
}

where:

Field	Command
new-uuid	uuid
files.sha1	sum -x sha1 /path/to/zvol.gz | cut -d' ' -f1
files.size	ls -l /path/to/zvol.gz | awk '{ print $5 }'
owner-uuid	sdc-ldap s 'login=admin' | grep ^uuid | cut -d' ' -f2
image-size	Size ypu want for C drive for instances created from this image in MiB (89120 is a good size)

Then:

imgadm install -m /zones/stuff/windows.imgmanifest -f /zones/stuff/windows.zvol

You can delete windows.imgmanifest and windows.zvol and the two ISO's.

You can now create in instance from the image.

Update the virtio

• Download the latest stable release from https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/stable-virtio/virtio-win.iso
• mount it (lets say its on D:)
• copy the .cat, .inf and .sys files from D:\viostor\2k22\amd64 to drivers/disk/amd64
• copy the .cat, .inf and .sys files from D:\NetKVM\2k22\amd64 to drivers/network/amd64 Replace 2k22 with the version of windows you're using
