environment_resources bodies
kvm
Prototype: kvm(name, arch, cpu_count, mem_kb, disk_file)
Description: An environment_resources
body for a KVM virtual machine.
The env_spec
attribute is set to a KVM XML specification.
Arguments:
name
: The name of the virtual machinearch
: The architecturecpu_count
: The number of CPUs the virtual machine should havemem_kb
: The amount of RAM in kilobytedisk_file
: The file on the host system for the virtual machine's harddrive
Example:
code
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")
}
Implementation:
code
body environment_resources kvm(name, arch, cpu_count, mem_kb, disk_file)
{
env_spec =>
"<domain type='kvm'>
