# Guest environments bodies

body environment_resources kvm(name, arch, cpu_count, mem_kb, disk_file)
# @brief An `environment_resources` body for a KVM virtual machine.
#
# The `env_spec` attribute is set to a KVM XML specification.
#
# @param name The name of the virtual machine
# @param arch The architecture
# @param cpu_count The number of CPUs the virtual machine should have
# @param mem_kb The amount of RAM in kilobyte
# @param disk_file The file on the host system for the virtual machine's harddrive
#
# **Example:**
#
# ```cf3
# bundle agent manage_vm
# {
# guest_environments:
#   am_vm_host::
#     "db_server"
#       environment_host      => atlas,
#       environment_type      => "kvm",
#       environment_state     => "create",
#       environment_resources => kvm("PSQL1, "x86_64", "4", "4096", "/var/lib/libvirt/images/psql1.iso")
# }
# ```
