# list specific vm

# create, remove vm

# we can also specify specific vm 'id' when initiating an object
# so we can direct access the element for specific vm

Attributes

Other attributes is also inherited from Ovirt.pm
Check 'perldoc Ovirt' for detail

notes :
ro                     = read only, can be specified only during initialization
rw                     = read write, user can set this attribute
rwp                    = read write protected, for internal class

vm_url                 = (ro) store default vm url path                  
vm_cdrom_xml           = (ro) store xml to be post on start/stop vm action with boot device set to cdrom
vm_hd_xml              = (ro) store xml to be post on start/stop vm action with boot device set to hd
vm_boot_dev            = (rw) set boot device when start / stopping vm, default to hd
vm_output_delimiter    = (rw) specify output delimiter between attribute, default is '||'
vm_output_attrs        = (rw) store vm attributes to be returned, default is (id, name, state)
                         supported attributes :
                           id          name    
                           memory      description

                           cpu_sockets cpu_arch
                           cpu_shares  os_type
                           boot_dev    ha_enabled
                           ha_priority display_type
                           cluster_id  template_id
                           stop_time   creation_time

SUBROUTINES/METHODS

BUILD

The Constructor, build logging, call pass_log_obj method
Built root_url with vm_url
set output with get_api_response method from Ovirt.pm
check if output attributes is valid

list_xml

return xml output

vm_action_output

this method handle the output e.g start / stop vm
required arguments ($xml), output passed by start/stop method

if ($status eq 'complete') {
    my $jobid = $xml->findnodes('/action/job/@id');
    print "status   : $status\n";
    print "jobid    : $jobid\n";
}
elsif ($status =~ /failed/) {
    # get fault reason and detail
    my $reason  = $xml->findnodes('/action/fault/reason');
    my $detail  = $xml->findnodes('/action/fault/detail');

    print "status   : $status\n";
    print "reason   : $reason\n";
    print "detail   : $detail\n";
}

remove

remove vm

create

create vm using template
required arguments (vm name, cluster name, template name)
optional argument 'memory in bytes'
example :
# with memory specified 
$vm->create('vm1', 'production_cluster', 'RHEL7', 1073741824);

# without memory specified (will be based on template's memory)
$vm->create('vm1', 'production_cluster', 'RHEL7');

    my $status    = $output->findnodes('/fault/reason');
    my $detail    = $output->findnodes('/fault/detail');
    print "status   : $status\n";
    print "detail   : $detail\n";
}

start

start vm
required arguments ($vmid)
if $self->id is set during initialization, argument is not required

stop

stop vm
required arguments ($vmid)
if $self->id is set during initialization, argument is not required

reboot

reboot vm
required arguments ($vmid)
if $self->id is set during initialization, argument is not required

migrate

migrate vm
required arguments ($vmid)
if $self->id is set during initialization, argument is not required

is_vmid_valid

return false if vmid not valid

list

return vm's attributes text output from hash_output attribute
if no argument spesified, it will return all vm attributes (based on vm_output_attrs)
argument supported is 'vm id'
example :
$vm->list('b4738b0f-b73d-4a66-baa8-2ba465d63132');

get_vm_by_element_id

This method is used by list method to list all vm attribute requested
An array element id and attribute name is required

get_vm_by_self_id

This method is used by list method if $self->id is defined
The id is set during initialization (id => 'vmid')
attribute name is required
