How to create a KVM OpenBSD root filesystem for VNX

Follow this procedure to create a KVM OpenBSD based root filesystem for VNX. The procedure has been tested with OpenBSD 5.8.

Basic installation

  • Create the filesystem disk image:
  • # 32 bits
    qemu-img create -f qcow2 vnx_rootfs_kvm_openbsd.qcow2 12G
    # 64 bits
    qemu-img create -f qcow2 vnx_rootfs_kvm_openbsd64.qcow2 12G
    
  • Get OpenBSD installation CD. For example:
  • # 32 bits
    wget http://mirror.meerval.net/pub/OpenBSD/5.9/i386/install59.iso
    mv install59.iso /almacen/iso/openbsd-install59-i386.iso
    # 64 bits
    wget http://ftp.eu.openbsd.org/pub/OpenBSD/5.9/amd64/install59.iso
    mv install59.iso /almacen/iso/openbsd-install59-amd64.iso
    
  • Create the virtual machine with:
  • # 32 bits
    vnx --create-rootfs vnx_rootfs_kvm_openbsd.qcow2 --install-media /almacen/iso/openbsd-install59-i386.iso --mem 512M
    # 64 bits
    vnx --create-rootfs vnx_rootfs_kvm_openbsd64.qcow2 --install-media /almacen/iso/openbsd-install59-amd64.iso --mem 512M --arch=x86_64
    
  • Follow OpenBSD installation menus to install a basic system:
    • When asked about the network interface, answer "done" to not configure the network now.
    • Answer 'yes' to the question "Change the default console to com0" to enable serial console.
    • Add a user named "vnx".
    • Use the whole "wd0" or "sd0" disk and "Auto layout".
    • Choose cd0 for the "location of sets". Choose the default "sets".
  • After ending installation, but before shutting down the virtual machine, you have to disable mpbios, as follows:
  • chroot /mnt
    config -ef /bsd
    disable mpbios
    quit
    
  • Finally, halt the system:
  • halt -p
    

The OS installer will offer to reboot, but do not do that. Instead, close the VM console window and then, from the host OS, destroy the virtual machine:

# virsh list
 Id    Nombre                         Estado
----------------------------------------------------
 33    vnx_rootfs_kvm_openbsd-5.9-v025.qcow2-7440 ejecutando

# virsh destroy 33

Configuration

  • Start the system with the following command:
  • # 32 bits
    vnx --modify-rootfs vnx_rootfs_kvm_openbsd.qcow2 --update-aced --mem 512M
    # 64 bits
    vnx --modify-rootfs vnx_rootfs_kvm_openbsd64.qcow2 --update-aced --mem 512M --arch x86_64
    

    Note: ignore the errors "timeout waiting for response on VM socket".

  • Access the system through the text console to easy the copy-paste of commands:
  • # virsh list
    Id    Name                           State
    ----------------------------------------------------
    31    vnx_rootfs_kvm_openbsd64-5.9-v025.qcow2-912 running
     
    # virsh console 31
    
  • In case you do not have access to the serial console, you can configure it manually by editting /etc/ttys file and changing the line:
  • tty00 "/usr/libexec/getty std.9600"   dialup  off secure
    

    to:

    tty00 "/usr/libexec/getty std.9600"   vt100  on secure
    

    Reboot the system after modifying the ttys file.

  • Loogin as root in the console and configure the network with DHCP:
  • dhclient re0
    
  • Configure the environment variable with network repository:
  • export PKG_PATH=ftp://ftp.eu.openbsd.org/pub/OpenBSD/`uname -r`/packages/`machine -a`/
    
  • Install bash and change package repository (change ftp.es.freebsd.org to your nearest mirror):
  • pkg_add -r bash  
    usermod -s /usr/local/bin/bash root
    usermod -s /usr/local/bin/bash vnx
    echo "export PKG_PATH=ftp://ftp.eu.openbsd.org/pub/OpenBSD/`uname -r`/packages/`machine -a`/" > ~/.bash_profile
    
  • Install XML::LibXML and NetAddr-IP perl libraries:
  • pkg_add -r p5-XML-LibXML p5-NetAddr-IP 
    
  • Install VNX autoconfiguration daemon:
  • mount_msdos /dev/wd1i /mnt  # if virtio=no in vnx.conf
    mount_msdos /dev/sd1c /mnt  # if virtio=yes in vnx.conf
    perl /mnt/vnxaced-lf/install_vnxaced
    
  • Create a file /etc/vnx_rootfs_version to store version number and informacion about modification:
  • VER=v0.25
    OS=OpenBSD 5.8
    DESC=Basic OpenBSD 5.8 root filesystem without GUI
    
  • Configure interface em0 so that it does not get configured with DHCP. To do that, if file /etc/hostname.em0 exists, edit it and delete or comment the line with "dhcp".
  • Stop the machine with that script:
  • vnx_halt
    

If everything went well, your root filesystem will be ready to be used with VNX. You can make a simple test using the simple_openbsd.xml (32 bits) or simple_openbsd64.xml (64 bits) scenario distributed with VNX.

Installing additional software

To install additional software or to modify your root file system, you just have to:

  • Start a virtual machine from it:
  • # 32 bits
    vnx --modify-rootfs vnx_rootfs_kvm_openbsd.qcow2
    # 64 bits
    vnx --modify-rootfs vnx_rootfs_kvm_openbsd.qcow2 --arch x86_64
    
  • Check network connectivity. Maybe you have to activate the network interface by hand:
  • dhclient re0
    
  • Do the modifications you want.
  • Finally, halt the system using:
  • vnx_halt
