Hi,
Is there a way to backup KVM Guest VM running CentOS Linux release
7.9.2009
(Core) OS in kvmguestosimage.ova or kvmguestosimage.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
Also any method to take full and incremental backup of KVM Guest VM.
Any help will be highly appreciated. I look forward to hearing from
you.
Thanks in Advance.

Stop the vm qemu-img convert -f raw origin.qcow2 dest.raw
You can then import but while we use this to create official centos image, don't forget to ensure that you node is ready to be imported, so cloud-init, etc, etc
It's usually easier/better/faster to have automation in place to configure an application and so replay it on a new node, and then replicate data
I guess only option why you'd want to not do this is that it's a
running
machine that was configured "by hands" by someone who left the company (and so without automation in place)

Thanks Fabian for the detailed email. I followed the below steps by referring to
https://docs.aws.amazon.com/vm-import/latest/userguide/vmimport-image-import...
.

*Step No. 1* #qemu-img convert -O vmdk openapibox.img openapibox.vmdk -p
I'm not 100% sure but I think that AWS only accepts the stream-optimized subformat, the command is:
$ qemu-img convert -O vmdk -o subformat=streamOptimized openapibox.img openapibox.vmdk
*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" }
Our project (https://www.osbuild.org/) uses the raw format for disks, uploads it to S3, calls import-snapshot to import it as an EBS snapshot and finally calls register-image to create a new AMI. Basically:
$ qemu-img convert -O raw openapibox.img openapibox.raw # upload into S3 $ aws ec2 import-snapshot ... # wait for the snapshot to be imported $ aws ec2 register-image ...
Docs:
https://docs.aws.amazon.com/cli/latest/reference/ec2/import-snapshot.html
https://docs.aws.amazon.com/vm-import/latest/userguide/vmimport-import-snaps...
If you want to see this in practice, we have some Go code. As awscli is just a thin wrapper over the API, it should be pretty easy to translate our code into awscli calls:
https://github.com/osbuild/osbuild-composer/blob/bfd90cf191eece5c1331dcb43a8...
Hope that helps,

Thanks Ondřej and appreciate it. I will try it out and keep you posted. Thanks in advance.
