Backup KVM Guest VM in OVA or VMDK format

[Kaushal Shriyan]

Hi,

Is there a way to backup KVM Guest VM in openapibox.img or openapibox.vmdk format as I am trying to restore it in AWS by referring to https://aws.amazon.com/ec2/vm-import/ article as per the below supported file format. 

[1] Open Virtualization Archive (OVA)
[2] Virtual Machine Disk (VMDK)
[3] Virtual Hard Disk (VHD/VHDX)
[4] raw

I followed the below steps by referring to https://docs.aws.amazon.com/vm-import/latest/userguide/vmimport-image-import.html. 

# qemu-img -h | grep Supported
Supported formats: blkdebug blklogwrites blkverify compress copy-before-write copy-on-read file ftp ftps gluster host_cdrom host_device http https iscsi iser luks nbd null-aio null-co nvme preallocate qcow2 quorum raw rbd ssh throttle vhdx vmdk vpc

# qemu-img --version
qemu-img version 6.2.0 (qemu-kvm-6.2.0-12.module_el8.7.0+1140+ff0772f9)

Step No. 1
#qemu-img convert -O vmdk openapibox.img openapibox.vmdk -p

Step No. 2
#aws ec2 import-image --disk-containers Format=vmdk,UserBucket="{S3Bucket=daclabservers,S3Key=openapidbox.vmdk}"
{
    "ImportTaskId": "import-ami-0232f452194f6efe0",
    "Progress": "1",
    "SnapshotDetails": [
        {
            "DiskImageSize": 0.0,
            "Format": "VMDK",
            "UserBucket": {
                "S3Bucket": "daclabservers",
                "S3Key": "openapibox.vmdk"
            }
        }
    ],
    "Status": "active",
    "StatusMessage": "pending"
}

Step No. 3
#aws ec2 describe-import-image-tasks --import-task-ids import-ami-0232f452194f6efe0
{
    "ImportImageTasks": [
        {
            "ImportTaskId": "import-ami-0232f452194f6efe0",
            "SnapshotDetails": [
                {
                    "DiskImageSize": 0.0,
                    "Status": "completed"
                }
            ],
            "Status": "deleted",
            "StatusMessage": "ClientError: Disk validation failed [Unsupported VMDK File Format]",
            "Tags": []
        }
    ]
}

 

Am I missing anything? Any help will be highly appreciated. I look forward to hearing from you. Please guide me.  Thanks in Advance. 

Best Regards,
