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_openbsd.qcow2 12G
# 32 bits wget http://mirror.meerval.net/pub/OpenBSD/5.8/i386/install58.iso mv install58.iso /almacen/iso/openbsd-install58-i386.iso # 64 bits wget http://ftp.eu.openbsd.org/pub/OpenBSD/5.8/amd64/install58.iso mv install58.iso /almacen/iso/openbsd-install58-amd64.iso
# 32 bits vnx --create-rootfs vnx_rootfs_kvm_openbsd.qcow2 --install-media /almacen/iso/openbsd-install58-i386.iso --mem 512M # 64 bits vnx --create-rootfs vnx_rootfs_kvm_openbsd64.qcow2 --install-media /almacen/iso/openbsd-install58-amd64.iso --mem 512M --arch=x86_64
- 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" disk and "Auto layout".
- Choose cd0 for the "location of sets" question if you have installed from the .iso disk as proposed here (you can alternatevely downloading packages from the network using http). Besides, you can update the system later. Choose the default "sets".
chroot /mnt config -ef /bsd disable mpbios quit
halt -p
The OS installer will offer to reboot, but do not do that. Instead, kill the VM window and then, in the host OS, interrupt with Ctrl-C the kvm program.
Configuration
- Start the system with the following command:
vnx --modify-rootfs vnx_rootfs_kvm_openbsd.qcow2 --update-aced --mem 512M --arch x86_64
Note: ignore the errors "timeout waiting for response on VM socket".

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 scenario distributed with VNX.
