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 must be installed and running.
The OS of the VM must have the local firewall disabled.
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. IPv6 must be disabled prior to 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.
WinRM must be able to start and TLS 1.2 must be enabled.
An Administrator privileged login 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.
- SSH logins 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 will be configured instead of the existing patching service subscription.
CentOS servers must have rhn pakages installed to qualfy for enrollment of the
patching service. Verify that the following packages are installed:
rhn-client-tools rhn-check rhn-setup rhnsd m2crypto yum-rhn-plugin
