What's this?

bhyve is the native FreeBSD Hypervisor (similar to xen, Linux KVM) which was introduced in FreeBSD 10. ezhyve's goal is easier creation of bhyve VMs. Currently a rc script and a startall feature are missing but its on the TODO list. Check it out for things ezhyve might not do for you yet.

ezhyve was inspired by erdgeist's sysutils/ezjail and is based on Michael Dexters bhyve-tools.

How to start

edit etc/ezhyve/ezhyve.conf to your needs! (PATHs)
you may also have to change the path to functions.sh and ezhyve.conf in bin/ezhyve.sh.

What features are currenly implementet

per vm configs (created via ezhyve.sh)
template support to make it easier to add new FreeBSD releases / Linux Distributions
ezhyve supports a couple of commands:

Usage

ezhyve.sh create vmname - create a config for an vm
ezhyve.sh start vmname - start vmname from image
ezhyve.sh stop vmname - stop / destroys vm
ezhyve.sh cdboot vmname - boots from iso file
ezhyve.sh provision vmname - provision an FreeBSD VM
ezhyve.sh delete vmname - deletes VM dir and config file
ezhyve.sh list - lists running vms
ezhyve.sh console vmname - connect to console of vmname
ezhyve.sh debug - TODO
ezhyve.sh grub vmname - grub

Options

ezhyve.sh create [-t FreeBSD (Linux, OpenBSD)] [-v 9.2-RELEASE (debian...)] [-m 1024 (RAM in MB)] [-d 2G (Disksize in GB)] [-p 1 (Num of. CPUs)] [-c default (console type)] [-l mbr (gpt)] [-o ahci-hd (virtio-blk)] [-D /dev/foo (e.g. zvol/zroot/vm0)] [-i /path/to/img.iso] vmname

cdboot from iso

this feature (-i) needs some more love!!

ezhyve.sh cdboot [-i /path/to/img.iso] vmname

What templates are available?

[root ~/wasted.io/ezhyve]# ls -R1 etc/ezhyve/vmtemplate/*
== FreeBSD ==
etc/ezhyve/vmtemplate/FreeBSD:
10.0-RC4
10.0-RC5
10.0-RELEASE
11.0-CURRENT
9.1-RELEASE
9.2-RELEASE
9.2-STABLE

== Linux ==
etc/ezhyve/vmtemplate/Linux:
archlinux231201
centos6.5
debian7.3.0
dsl4.4.9
rhel7beta
slackware14.1
ubuntu13.04
ubuntu13.10

== OpenBSD ==
etc/ezhyve/vmtemplate/OpenBSD:
5.4

== pfSense ==
etc/ezhyve/vmtemplate/pfSense:
2.1

For -t use the directory names beneath etc/ezhyve/vmtemplate (FreeBSD, Linux ...).

For -v use the filename (without the .conf) in etc/ezhyve/vmtemplate/$EZHYVE_VM_TYPE/.

To create your own template just check out etc/ezhyve/vmtemplate.

RAM size, Disk size, cpu num ...

The following examples will create a VM config with default settings:

: ${EZHYVE_RAMSIZE=512} # in MB
: ${EZHYVE_DISKSIZE="2G"} # in GB
: ${EZHYVE_CPUNUM=1} # INT

To change these defaults see ezhyve.conf, but you can also create a VM config like this:

ezhyve.sh create -m 1024 -d 5G -p 2 VMname

This would give the VM 1024MB ram, an 5G image would be created with 2 cpus.

Just call ezhyve.sh create for usage.

Creating a FreeBSD VM

# creating the vm template
ezhyve.sh create vmname
# -t FreeBSD supports cdboot and provisioning ... only one at a time makes sense ;)
ezhyve.sh provision vmname
ezhyve.sh cdboot vmname
# adjust FBSD_DISTFILES in ezhyve.conf; defaults to base.txz and kernel.txz
# if you dont have the iso yet you can fetch it
ezhyve.sh fetch vmname
# start the vm
ezhyve.sh start vmname
# connect to console if EZHYVE_CONSOLE is nmdm, lpc, tmux
ezhyve.sh console vmname

ezhyve.sh create VMfreebsd10 # this would create a FreeBSD 10.0-RELEASE vm config
ezhyve.sh create -t FreeBSD -v 9.2-RELEASE VMfreebsd # this would create a FreBSD 9.2-RELEASE VM

Creating a Linux VM

Here you have to ALWAYS specify -t and -v
# creating the vm template
ezhyve.sh create -t Linux -v ubuntu13.10 vmname
# only cdboot is supported for installation
ezhyve.sh cdboot vmname
# if you dont have the iso you can fetch it before cdboot
ezhyve.sh fetch vmname
# you may have to stop the Linux VM after installation is finished
ezhyve.sh stop vmname
# start the vm
ezhyve.sh start vmname
# connect to console if EZHYVE_CONSOLE is nmdm, lpc, tmux
ezhyve.sh console vmname

Provision a FreeBSD VM

See fbsdprovision() in functions.sh ... it's on the TODO list to make this more customizable

dhcp
empty root pw
PermitRootLogin yes
/etc/rc.conf created
/etc/fstab created
/etc/ttys edited

Stopping a VM

ezhyve.sh stop vmname

Deleting the VM config and the VM directory (device.map, image)

ezhyve.sh delete vmname

Linux VMs still make kinda trouble ...

I had some luck booting an Ubuntu and an Debian but not so much with the other ones.

I got a lot of black consoles with no response so if you want to see the commands grub-bhyve tried to execute have a look at

$PATH_BHYVEVMS/$EZHYVE_VM_NAME/GRUBBOOTCMD
$PATH_BHYVEVMS/$EZHYVE_VM_NAME/GRUBISOCMD

Using an existing Image

Create an VM config via

ezhyve.sh create vmname

and instead of provisioning or cdboot to install it just copy your existing image file (and device.map) to $PATH_BHYVEVMS/$EZHYVE_VM_NAME/$EZHYVE_VM_NAME.img

Now all you need to do is

ezhyve.sh start vmname
