VM migration from vmware to kvm failed.

[nemethga]

We have ACS 4.22 environment with KVM and we are testing VM conversion from vmware to acs. Test VM is stopped OL8 linux. The following error occurred during migration. The error is from KVM cloudstack agent log. Where could the problem be? Vcenter is available.

• Where can I find a more detailed description of the functionality of individual parts of the migration tool?
• What should be the correct settings on the vcenter side?
• What services must be running on vcenter?
• I found out that the error could be related to the running of the vmware-sps service on the server?

Thanks for your help

@nemethga it seems kvm host is unable to reach the vcenter vc01.testdomain.sk, can you manually try the ovftool cmd and verify it?

[nemethga]

How do I properly verify whether vCenter is accessible from a KVM host?.

I try reach from vcenter from kvm using:
ovftool --noSSLVerify vi://**@vc01.testdomain.sk:443/PosAm DC/vm/Development/_noBCK/test-vm-01 /mnt/

There is log from ovftool.

Any update for this issue?

I have seen many videos that you have shown in the labs, how to migrate vm from vmware to kvm through this tool. It seems that it is not at all tight, I do not know how it is usable in a production environment.

We do not know how to resolve error conditions and I have no idea how to run this conversion tool. Is there anyone here who has the conversion working and uses it in real conditions?

Thanks

it looks like your kvm host running the ovftool cannot reach the vcenter.
