| Minimum System Requirements |
| --------------------------- |
| |
| |
| Management Server, Database, and Storage System Requirements |
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
| |
| The machines that will run the Management Server and MySQL database must |
| meet the following requirements. The same machines can also be used to |
| provide primary and secondary storage, such as via localdisk or NFS. The |
| Management Server may be placed on a virtual machine. |
| |
| - Operating system: |
| |
| - Preferred: CentOS/RHEL 6.3+ or Ubuntu 12.04(.1) |
| |
| - 64-bit x86 CPU (more cores results in better performance) |
| |
| - 4 GB of memory |
| |
| - 250 GB of local disk (more results in better capability; 500 GB |
| recommended) |
| |
| - At least 1 NIC |
| |
| - Statically allocated IP address |
| |
| - Fully qualified domain name as returned by the hostname command |
| |
| |
| Host/Hypervisor System Requirements |
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
| |
| The host is where the cloud services run in the form of guest virtual |
| machines. Each host is one machine that meets the following |
| requirements: |
| |
| - Must support HVM (Intel-VT or AMD-V enabled). |
| |
| - 64-bit x86 CPU (more cores results in better performance) |
| |
| - Hardware virtualization support required |
| |
| - 4 GB of memory |
| |
| - 36 GB of local disk |
| |
| - At least 1 NIC |
| |
| - Latest hotfixes applied to hypervisor software |
| |
| - When you deploy CloudStack, the hypervisor host must not have any VMs |
| already running |
| |
| - All hosts within a cluster must be homogeneous. The CPUs must be of |
| the same type, count, and feature flags. |
| |
| Hosts have additional requirements depending on the hypervisor. See the |
| requirements listed at the top of the Installation section for your |
| chosen hypervisor: |
| |
| .. warning:: |
| Be sure you fulfill the additional hypervisor requirements and installation |
| steps provided in this Guide. Hypervisor hosts must be properly prepared to |
| work with CloudStack. For example, the requirements for XenServer are |
| listed under Citrix XenServer Installation. |
