The Oracle Cloud Infrastructure Compute service enables you to import your older operating systems to Oracle Cloud Infrastructure. You can import a wide range of new and legacy production operating systems, using the QCOW2 or VMDK formats, and then run them on Mojito Gray Scarpa Scarpa Gray Mojito Scarpa Gray Gray Mojito Scarpa Mojito Scarpa Compute virtual machines (VMs) using emulated hardware. The following table lists the operating systems that are supported for emulation mode VMs:
|RHEL||4.5, 5.9, 5.11, 6.9, 7.4|
|CentOS||4.0, 4.8, 5.11, 6.9, 7.x|
|Oracle Linux||4.5, 4.8, 5.8, 5.11, 6.2, 6.5, 6.9, 7.4|
|Ubuntu||12.04, 14.04, 16.04|

- Oracle Cloud Infrastructure has tested the operating systems listed in the previous table and will support customers in ensuring instances launched from these images and built according to the guidelines outlined in this topic are accessible using SSH or RDP.
- For operating systems and operating system versions not listed above Oracle Cloud Infrastructure will provide commercially reasonable support to customers in an effort to get instances launched from these images accessible via SSH or RDP.
- Support from Oracle Cloud Infrastructure in launching an instance from a custom operating system does not ensure that the operating system vendor will support the instance. Customers running Oracle Linux on Oracle Cloud Infrastructure automatically have access to Oracle Linux Premier Support, see Oracle Linux for more information.
Custom Image Requirements
Linux-based and Windows-based custom images imported for emulation mode VMs must meet the following requirements:
The image must be set up for BIOS boot.
The maximum image size is 300 GB.
Only one disk is supported, and it must be the boot drive with a valid MBR and boot loader. You can migrate additional data volumes after the image's boot volume has been imported.
The boot process must not require additional data volumes to be present for a successful boot.
The disk image cannot be encrypted.
The disk image must be a VMDK or QCOW2 file. VMDK files must be either the "single growable" (monolithicSparse) type or the "stream optimized" (streamOptimized) type, both of which will consist of a single VMDK file. All other VMDK formats such as those that use multiple files, split volumes, or contain snapshots, are not supported.
Existing network interfaces will not be recreated. Instead, a single network interface will be created after the import process is complete. You should use DHCP on this interface to discover the network settings.
Requirements Specific to Linux-Based Custom Images
The following requirements are only applicable to Linux-based custom images:
The boot loader should use LVM or UUID to locate the boot volume.
The network configuration should not hardcode the MAC address for the network interface.
For Linux-based instances, we recommend that you enable certificate-based SSH, however this is optional. If you want your image to automatically use ssh keys supplied from the User Data field when you launch an instance, you can install Cloud-Init when preparing the image. See Creating an Instance for more information about the User Data field.
Custom Image Import Process
The following is a high-level outline of the steps required to import custom images for emulation mode VMs.
Prepare the image for import. This includes enabling serial console access for all Linux-based custom images and configuring a network interface without a static MAC address and to support DHCP. For more information, see Preparing a Custom Linux Image for Emulation Mode and Red Women'S Shoes Blue Sandals Toe Dress Sandals Blue Black Wedding Satin Peep Purple Stretch vBaqwxgvS.
Export the image as VMDK or QCOW2 format using existing virtualization tools. See the tools documentation for your virtualization environment.
Upload the image to Mojito Scarpa Mojito Scarpa Scarpa Gray Gray Gray Scarpa Gray Scarpa Mojito Mojito Oracle Cloud Infrastructure Object Storage. See white Sable Nike Max Dãsert Off Training Gris 054 Air Women’s Atmosphã¨re WMNS Prem Blanc 90 zzgZq8w and Overview of Object Storage for more information.
Import the image. See Importing Custom Images for Emulation Mode.
