The KVM provider creates virtual images for Linux Kernel-based Virtual Machines. It supports the installation of virtio kernel modules (paravirtualized drivers for IO operations). It also supports creating an image with LVM and qcow2 as a disk backend.

Manifest settings


  • virtio: Specifies which virtio kernel modules to install. optional
  • console: Specifies which console should be used for stdout and stderr of init process to show startup messages and act as a console in single-user mode. Regardless of this setting output of kernel messages generated by printk() and seen by dmesg goes to both virtual and serial console. Valid options: `virtual` or `serial` (default). optional
  • logicalvolume: Specifies the logical volume where the disk image will be built.
  • volumegroup: Specifies the volume group where the logical volume will be stored. These options should only be used if lvm was given as a disk backend.
