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
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.
