runV

runV is a hypervisor-based runtime for OCF.

OCF

runV is compatible with OCF. However, due to the difference between hypervisors and containers, the following sections of OCF don't apply to runV:

• Namespace
• Capability
• Device
• linux and mount fields in OCI specs are ignored

Hypervisor

The current release of runV supports the following hypervisors:

• KVM (QEMU 2.0 or later)
• Xen (4.5 or later)
• VirtualBox (Mac OS X)

Distro

The current release of runV supports the following distros:

• Ubuntu 64bit
  • 15.04 Vivid
  • 14.10 Utopic
  • 14.04 Trusty
• CentOS 64bit
  • 7.0
  • 6.x (upgrade to QEMU 2.0)
• Fedora 20-22 64bit
• Debian 64bit
  • 8.0 jessie
  • 7.x wheezy (upgrade to QEMU 2.0)

Build

# create a 'github.com/hyperhq' in your GOPATH/src
cd $GOPATH/src/github.com/hyperhq
git clone https://github.com/hyperhq/runv/
cd runv
./autogen.sh
./configure --without-xen
make
sudo make install

Run

To run a OCF image, execute runv with the OCF JSON format file as argument, or have a config.json file in CWD.

Also, a kernel and initrd images are needed too. We recommend you to build them from HyperStart repo. If not specified, runV will try to load the kernel and initrd.img files from CWD.

runv --kernel kernel --initrd initrd.img

Example

Please check the runC example to get the container rootfs. https://github.com/opencontainers/runc#examples

And you can get a sample OCF config.json at https://github.com/opencontainers/runc#oci-container-json-format or simply execute runv spec.
