Before a VM can be enrolled in Guest OS Services, it must meet the following requirements:
Rackspace encourages the use of the Rackspace complementary VM templates when deploying VMs that will be enrolled in Guest OS Services. Rackspace OS Administrators are accustomed to the operating system configurations of these VM templates.
- The VM OS must be a supported type and version.
- VM is powered on.
- VMware Tools version 10.x is installed and running.
We recommended that the latest supported version of VMware tools is installed for best results during the automated enrollments.
- The OS of the VM must have the local firewall disabled and allow remote access and privileged process execution by the enrollment account.
- Two Factor Authentication (2FA) must not be enabled for the enrollment
account or the
rackuser account created during the enrollment process.
- The VM must have at least one NIC connected to a physical network with at least one IPv4 IP address configured that matches the physical network topology.
Guest OS Services does not support IPv6 addresses. You must disable IPv6 before enrollment in Guest OS Services.
PowerShell v3 or higher must be installed.
If MaxMemoryPerShellMB quota is increased for PowerShell v3, you must apply hotfix 2842230 or update to a newer version of PowerShell. If applying the hotfix, MaxMemoryPerShellMB should be set to 2048.
You must disable User Account Control (UAC) for all users that are members of the local Administrators group.
WinRM must be able to start and TLS 1.2 must be enabled.
An Administrator-privileged login for remote access must be provided for enrollment.
Remote Desktop sessions must be enabled.
For servers joined to customer Active Directory, AD DNS service must be configured with Rackspace DNS forwarders. Contact your account team for details.
For servers joined to customer Active Directory, any group policy settings active for the servers being enrolled in Guest OS Services must not conflict with or revert any of the changes being made during or after enrollment.
- Remote SSH logins for the user credential provided must be allowed.
- A root privileged login must be provided for enrollment.
- A valid repo must be configured for dependent package installation.
- All invalid repo references should be removed, including original ISOs used
The valid repo requirement does not apply if Rackspace patching is selected.
- Customer-provided RHEL licensing must not be in use. If the patching service is selected, the Rackspace patching service is configured instead of the existing patching service subscription.
- CentOS servers must have rhn packages installed to qualify for enrollment of
patching service. Verify that the following packages are installed:
rhn-client-tools rhn-check rhn-setup rhnsd m2crypto yum-rhn-plugin
