reveal_myself($self)
Any subroutine calls this subroutine announces its identity and it is being executed.
create($self)
Create guest instance by assigning values to its parameters but do no install it.
initialize_guest_params($self)
Initialize all guest parameters to avoid uninitialized parameters.
config_guest_params($self, %_guest_params)Assign real values to guest instance parameters. Reset [guest_name] to guest name used in [guest_metadata] if they are different. The subroutine can be called mainly in two different ways: Firstly, config_guest_params can be called in another subroutine, for example, create which takes a hash/dictionary as argument. my %testhash = ('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3'), $self->create(%testhash) which calls $self->config_guest_params(@_). Secondly, config_guest_params can also be called direcly, for example, $self->config_guest_params(%testhash). Call revise_guest_version_and_build to correct guest version and build parameters to avoid mismatch if necessary.
revise_guest_version_and_build($self, %_guest_params)Correct [guest_version], [guest_version_major], [guest_version_minor] and [guest_build] if they are not set correctly or mismatch with each other. Set [guest_version] to the developing product version if it is not given. Set [guest_version_major] and [guest_version_minor] from [guest_version] it they do not match with [guest_version]. Set [guest_build] to get_required_var('BUILD') if it is empty and developing [guest_version], or 'GM' if non-developing [guest_version].

$_bridge_network_in_route, $_bridge_device)Create [guest_network_device] by writing device information into ifcfg file in /etc/sysconfig/network. Mark guest installation as FAILED if [guest_network_device] can not be successfully started up. If [guest_network_device] or [guest_netaddr] already exists and active on host judging by 'ip route show', both of them will not be created anyway.
config_guest_network_bridge_services($self, $_guest_network_device,
$_guest_network_ipaddr_gw, $_guest_network_mask, $_guest_network_ipaddr_start,
$_guest_network_ipaddr_end, $_guest_network_ipaddr_rev)Start DHCP and DNS services by using dnsmasq command line. Add parsed subnet gateway ip address and [guest_domain_name] into /etc/resolv.conf. Empty NETCONFIG_DNS_POLICY in /etc/sysconfig/network/config. Mark guest installation as FAILED if dnsmasq command line can not be successfully fired up.

User can still change [guest_installation_method], [guest_installation_media], [guest_build], [guest_version], [guest_version_major], [guest_version_minor], [guest_installation_fine_grained] and [guest_autoconsole] by passing non-empty arguments using hash.Call config_guest_installation_media to set correct installation media.
config_guest_installation_media($self)Set [guest_installation_media] to the current major and minor version if it does not match with [guest_version]. This subroutine also help mount nfs share if guest chooses to or has to use iso installation media, for example oracle linux guest uses iso installation media from https://yum.oracle.com/oracle-linux-isos.html. For guest using pre-built virtual disk image which will be downloaded and saved to [guest_storage_backing_path]. Although this subroutine can help correct installation media major and minor version if necessary, it is just auxiliary functionality and end user should always pay attendtion and use the meaningful and correct guest parameters and profile.

The well-known provisioning tools are ignition and combustion which are specified by [guest_installation_automation_method]. Use flavors of supported platform from igntion as [guest_installation_automation_platform]. If provisioning config is passed in to [guest_sysinfo], user does not need to specify [guest_sysinfo] in guest profile. Instead only [guest_installation_automation_file] needs to be specified, all the others are taken care by this subroutine. Please refer to documentation: https://coreos.github.io/ignition/ and https://github.com/openSUSE/combustion.
config_guest_provision_ignition($self)Configure ignition config file based on template specified by [guest_installation_automation_file]. If [guest_installation_automation_file] is empty, default ones will be used. If [guest_installation_automation_method] is 'ignition+combustion', their respective configuration files will be specified and joined with '#', for example, 'ignition_config #combustion_config', and their names should be prefixed with 'ignition' or 'combustion' respectively. Based on [guest_installation_automation_platform], for example, 'qemu' or 'metal', different ways of generating the final [guest_installation_automation_options] will be adopted. If [guest_installation_automation_platform] is 'qemu', ignition config file will be passed in via '--sysinfo' directly. If [guest_installation_automation_platform] is 'metal', ignition config file will be placed in the secondary disk vdb which is created by calling config_guest_provision_disk.
config_guest_provision_ignition_luks($self[, _ignition_config => 'config'])This subroutine is responsible for configuring luks devices in ignition config file. For details of luks devices in ignition, please refer to https://coreos.github.io/ignition/configuration-v3_2/.
config_guest_provision_combustion($self)If [guest_installation_automation_method] is 'ignition+combustion', configuring combustion will be done after ignition. Combustion only is not supported, because 'ignition' or 'ignition+combustion' can already cover all scenarios. If [guest_installation_automation_file] is empty, default ones will be used. If [guest_installation_automation_method] is 'ignition+combustion', their respective configuration files will be specified and joined with '#', for example, 'ignition_config #combustion_config', and their names should be prefixed with 'ignition' or 'combustion' respectively. Based on [guest_installation_automation_platform], for example, 'qemu' or 'metal', different ways of generating the final [guest_installation_automation_options] will be adopted. If [guest_installation_automation_platform] is 'qemu', ignition config file will be passed in via '--sysinfo' directly. If [guest_installation_automation_platform] is 'metal', ignition config file will be placed in the secondary disk vdb which is created by calling config_guest_provision_disk.
config_guest_provision_disk($self[, _provision_tool => 'tool'])If [guest_installation_automation_platform] is 'metal', both ignition and combustion configurations will be placed in respective folders in the secondary disk vdb which is labeled as 'ignition"'. Because only 'ignition' or 'ignition+combustion' is supported, config_guest_provision_ignition will create a new ignition disk and config_guest_provision_combustion will only open an existing ignition disk to place combustion configuration in it.
config_guest_installation_automation($self[, key-value of automated installation arguments])Configure guest automatic installation. Based on [guest_installation_automation_method], either calling config_guest_firstboot_provision or config_guest_unattended_installation. The former is responsible for generating configuration for automatic firstboot provision which is used by booting from virtual disk image directly. The latter is responsible for generating unattended installation configuration for a fresh installation from installation media.
config_guest_unattended_installation($self)Configure [guest_installation_automation_options]. Fill in unattended installation file with [guest_installation_media], [guest_secure_boot], [guest_boot_settings], [guest_storage_label], [guest_domain_name], [guest_name] and host public rsa key. User can also change [guest_do_registration], [guest_registration_server], [guest_registration_username], [guest_registration_password], [guest_registration_code], [guest_registration_extensions] and [guest_registration_extensions_codes] which are used in configuring guest installation automation registration. Subroutine config_guest_installation_automation_registration is called to perform this task. Start HTTP server using python3 modules in unattended automation file folder to serve unattended guest installation.Mark guest installation as FAILED if HTTP server can not be started up or unattended installation file is not accessible. Common varaibles are used in guest unattended installation file and to be replaced with actual values.They are common variables that are relevant to guest itself or its attributes, so they can be used in any unattended installation files regardless of autoyast or kickstart or others.For example, if you want to set guest ethernet interface mac address somewhere in your customized unattended installation file, put ##Device-MacAddr## there then it will be replaced with the real mac address. The actual kind of automation used matters less here than variables used in the unattended installation file, so keep using standardized common varialbes in unattened installation file will make it come alive automatically regardless of the actual kind of automation being used. Currently the following common variables are supported:[Module-Basesystem, Module-Desktop-Applications, Module-Development-Tools, Module-Legacy, Module-Server-Applications, Module-Web-Scripting, Product-SLES, Authorized-Keys, Secure-Boot, Boot-Loader-Type, Disk-Label, Domain-Name, Host-Name, Device-MacAddr, Logging-HostName, Logging-HostPort, Do-Registration, Registration-Server, Registration-UserName, Registration-Password and Registration-Code].
validate_guest_installation_automation_file($self)Validate autoyast file using xmllint and yast2-schema. This is only for reference purpose if guest and host oses have different release major version. Output kickstart file content directly because its content can not be validated on SLES or opensuse host by using ksvalidator.
config_guest_installation_command($self)Assemble all configured options into one virt-install command line to be fired up for guest installation. If certain options that have special settings need to be further tweaked before final virt-install is formed, corresponding work should also be done in this subroutine as well, for example, applying authentic plain passwords to be used. This subroutine does not receive any other passed in arguments.
config_guest_plain_password($self)Before guest installation starts or during its installation, plain passwords might be used to facilitate configuring, installing or investigating guest, for example, a ssh root password is usually used to enable password access to linuxrc via ssh when performing guest installation with autoyast or kickstart. User can put HOLDER ROOTPASSWORD in guest profile to indicate that plain password is expected. If a different plain password is used at the same time, a different HOLDER name can be used as well in either guest profile or provision/unattended installation file. Root plain password should be saved in $testapi::apassword, but customized one can be chosen by specific setting _SECRET_ROOT_PASSWORD. This subroutine does not receive any other passed in arguments.
guest_installation_run($self, @_)Calls prepare_guest_installation to do guest configuration. Call start_guest_installation to start guest installation. This subroutine also accepts hash/dictionary argument to be passed to prepare_guest_installation to further customize guest object if necessary.

If needle 'text-login' is detected,this means guest installations finishes. Mark it as PASSED if ssh connection is good,otherwise mark it as FAILED. If needle 'grub2' is detected,this means guest is rebooting. Will check its result in the next round. If needle 'text-logged-in-root' is detected,this means installation screen is disconnected, terminated or broken.Will try to re-attach and check its result in the next round. If needle 'guest_installation_in_progress' is detected,this means installation is still in progress. Will check its result in the next round. If none of above needles is detected, makr it as PASSED if ssh connection to it is good, otherwise mark it as FAILED by calling check_guest_installation_result_via_ssh.
check_guest_installation_result_via_ssh($self)Get guest ip address and check whether it is already up and running by using ip address and name sequentially. Use very common linux command 'hostname' to do the actual checking because it is almost available on any linux flavor and release.
attach_guest_installation_screen($self)Attach guest installation screen before monitoring guest installation progress: If [guest_installation_session] is not available and no [guest_autoconsole], call do_attach_guest_installation_screen_without_sesssion. If [guest_installation_session] is not available and has [guest_autoconsole], call get_guest_installation_session, then attach based on whether installation session is available. If [guest_installation_session] is already available,call do_attach_guest_installation_screen directly.
do_attach_guest_installation_screen($self)Call do_attach_guest_installation_screen_with_session anyway. Mark [guest_installation_attached] as true if needle 'text-logged-in-root' can not be detected.
