Configuring Container
The Migrate Physical Server to Container: Configure Container page allows you to configure a Container into which you can migrate your physical server.
When configuring the Container for the migration of a Windows-based server, the only information to provide is the Container ID in the Container Configuration group. You can either opt for selecting the Container ID automatically (the Select Container ID automatically radio button), or assign the Container the ID to fit in your Containers nomenclature. The Container ID is a 32-bit (ranging from 0 to 4294967295) integer number over 100. (Detailed information on the Container IDs allocation can be viewed in the Choosing Container ID subsection of the Parallels Virtuozzo Containers User's Guide.) To enable the feature, select its checkbox.
By default, most Container parameters, such as Container hostname, IP address(es), DNS server(s) and hostname lookup parameters are inherited from the physical server and are displayed on this page in the appropriate fields. By editing these parameters you can apply your own values. Mind though that you do so at your own risk, and if you are not quite expert in the matter, the recommendation is to leave the default settings. On this page you can verify or edit Container general settings that are divided into three groups for your convenience: configuration parameters, network parameters, and advanced parameters.
The Configuration group enables you to perform the following operations:
- Select a Container sample you want the Container to be based on;
- Choose an OS template and its version you wish the Container to be based on. By default, Parallels Infrastructure Manager automatically searches for the most compatible OS template. However you can change the OS template if needed.
- Select the Customize resource settings checkbox, which allows you to adjust resource parameters on the next page of the wizard. This operation is optional.
The Network group lets you do the following to define the network parameters:
- Verify the Container hostname. Mind that it is inherited from the physical server. Changing the hostname may result in future conflicts and malfunction.
- Assign an IP address to it. You can set several IP addresses for the Container by clicking the
icon to the right of the IP Address field. At the same time, clicking the
icon near the IP Address field will remove the corresponding IP address assigned to the Container. - Enter one or more DNS servers that this Container is supposed to use in the DNS server IP address field or leave it blank. By clicking the
or
icons you can add/remove, accordingly, the DNS servers IP addresses for the Container being configured. Note that the static values in these fields might be overridden if the Container gets the DNS servers from the DHCP server when operating in the bridged network mode. - Define a list for hostname lookup in the Search domain field or leave it blank. Use the
or
icons to add/remove the lookup parameters for the Container. The search list is normally determined by the domain name(s); by default, it contains the local domain name(s) only. You can also add external domain names for a particular Container. A search query is performed by attempting to use each item in the list in turn until a match is found. Note that this process may be slow and may generate a lot of network traffic if the servers for the listed domains are not local, and that the query might time out if no server is available for one of the domains. Note also that the static values in these fields might be overridden if the Container gets the search domains from the DHCP server when operating in the bridged network mode.
The Advanced group helps to specify the Container ID, a 32-bit (ranging from 0 to 4294967295) integer number over 100. (Detailed information on the Container IDs allocation can be viewed in the Choosing Container ID subsection of the Parallels Virtuozzo Containers User's Guide.) To enable the feature, select its checkbox.
