Rejviz [ray-veez], VM / disk image tools built on top of libguestfs-tools.

Currently rejviz-builder command is implemented.

A command that proxies to virt-builder and adds a custom --nic option, which allows to configure network interfaces on the image (files /etc/sysconfig/network-scripts/ifcfg-ethX). All other options are passed to virt-builder untouched.

The format of the --nic parameter is:

--nic name=NAME[,key=VALUE]...

key = {name|hwaddr|bootproto|ipaddr|network|netmask|broadcast}

The values which are not specified can often be inferred (or in case of hwaddr, autogenerated to a random KVM MAC address).

• If only name is specified, the bootproto is 'dhcp'.
• If name and ipaddr is specified, the bootproto is 'static' and and the other values are inferred as for a /32 network.

Example usage:

rejviz-builder centos-7.0 \
    -o mycentos.qcow2 --format qcow2 --size 15G \
    --hostname mycentos --root-password password:mypassword \
    --nic name=eth0 \
    --nic name=eth1,ipaddr=192.168.122.15 \
    --nic name=eth2,ipaddr=192.168.123.15

• Create a VM image
  • From base image
  • Having some size
  • With some script run
  • With network interfaces configured (some DHCP, some static IPs)
  • Subscribed via RHSM
• Create a VM
  • With network interface MAC addresses matching the interfaces from the image
  • With some RAM and vCPUs
• Amend existing VM image (or libvirt domain)
  • Reconfigure network interfaces
  • Re-subscribe via RHSM
• Tell me something about an image (or libvirt domain)
  • List network interfaces and their basic config
  • Check that MACs on the domain match MACs in /etc/sysconfig/network-scripts

• Creating an image
  • In: params
  • Out: image
  • rejviz-builder command that proxies to virt-builder and adds custom params on top (RHSM, network interfaces)
• Creating a VM
  • In: image and params
  • Out: domain XML or created domain (both through virt-install)
  • rejviz-install command that proxies to virt-install and determines some of the parameters from the image
• Amending an image (or libvirt domain)
  • In: (image or domname) and params
  • Out: image edited in place
  • rejviz-customize command that proxies to virt-customize and adds custom params on top (RHSM, network interfaces)
• Image/domain introspection
  • In: (image or domname) and params
  • Out: information printed
  • rejviz-peek
