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.

Best Regards,

Kaushal

  • Hi,

    I will appreciate it if someone can pitch in for my earlier post to this mailing list and need guidance in this regard. I look forward to hearing from you. Thanks in advance.

    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

    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/register-image.html
    – https://docs.aws.amazon.com/cli/latest/reference/ec2/import-snapshot.html
    –
    https://docs.aws.amazon.com/vm-import/latest/userguide/vmimport-import-snapshot.html

    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/bfd90cf191eece5c1331dcb43a85bcca02d8d7d4/internal/cloud/awscloud/awscloud.go#L211

    Hope that helps,

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