VMware migration tool: we need your feedback!

I have two different behaviour on two different XO instances. Each XO instance refers to a different pool (different hosts, same xcp-ng version). In both the instances I try to connect to the same Private Virtual Datacenter based on VMware/vSphere at OVH.

In the first one I get the following error message by using the web UI: "invalid parameters" (take a look at this logfile 2023-02-28T19_25_21.933Z - XO.txt )

In the second one, I get the following error message by using the web UI "404 Not Found https://<vsphere-ip>/folder/<vm-name>/<vm-name>.vmx?dsName=<datastore-name>"

By using the xo-cli I get the "404 Not Found" on both the instances.

Regarding the "404 Not Found", I want to point out that at OVH I have a VMware datacenter (with 2 hosts) and in order to access to the storage I need to specify the parameter dcPath=<datacenter-name>

So the right URL should be https://<vsphere-ip>/folder/<vm-name>/<vm-name>.vmx?dcPath=<datacenter-name>&dsName=<datastore-name>

Simply adding (in a static way) the dcPath specification on line :54 of esxi.mjs file makes it work.

Interesting, that's probably a parameter we need to add (as optional) in the case it's needed. Would you mind test a dedicated branch when @florent will add it?

ismo-conguairta

@olivierlambert Yeah sure! No problem, it'll be a pleasure.

Do you have any idea about the issue related to the message "invalid parameters"? Do you have any suggestion in order to go deeper? Thanks.

olivierlambert

No but @florent will take a look ASAP

For what it's worth I'm seeing the same invalid parameters error when I attempt to perform a migration from an on prem ESXI 7.0U2 host.

@Seclusion are you doing it while the VM is running on VMware side? If yes, that's normal then, the delta mode (VM on) isn't supported yet on ESXi > 6.5

Seclusion

@olivierlambert No, I thought doing a live migration seemed too ambitions to try first, but I also didn't realize that it also wasn't supported, haha. Here are my settings: Screenshot from 2023-02-28 17-41-20.png
and on on the esxi side:

I thought it was constant. I will look into the api to get it, and if not possible expose it in the UI

@Seclusion : noted I will look into theis error message, this one is a first for me

ismo-conguairta

@Seclusion @florent In my case the ESXi version is 7.0.3 (build 20842708) and the vCSA version is 7.0 (build 20845200). The VM I try to migrate is not running on VMware side.
The only difference between the 2 XO instances is that the first one is installed on a PV machine while the second one on a PVHVM machine.

florent

@ismo-conguairta @rajaa-b can you check it, I think the full SR object is sent to the backend when changing the sr from the default one to another , instead of the id

florent

@ismo-conguairta
Can you try this branch : https://github.com/vatesfr/xen-orchestra/pull/6694/files ?

Edit : I can get the dcPath from the esxi api, you can test from the frontend, no need to use the command line

For now you can't change the SR ( changing it will lead to a parameter error)

@florent I just checked the branch and I get this error message "404 Not Found https://<vsphere-host>/folder/<vm-name>/<vm-name>.vmx?dcPath=datacenter-61&dsName=<ds-name>"

where datacenter-61 is not the right reference to my datacenter. Please take a look at the following screenshot.

From documentation

dcPath is the inventory path to the Datacenter containing the Datastore.

@ismo-conguairta said in VMware migration tool: we need your feedback!:

inventory path to the Datacenter

I updated to use another property (from https://developer.vmware.com/apis/196/vsphere/doc/vim.Datacenter.html ) is it better ? on our lab, theses properties have the same value

ismo-conguairta

@florent I have just checked and your last update works like a charm. Great!

Hi folks,

I have an error when importing from VMware

I'm using XO from sources :

commit number : ea2c6
Hypervisor : Xcp-ng 8.2.1
node : 18.14.2

When I go on import and "from VMware", I put my ESX credentials, check "skip SSL", I do see the list of my VMs from my ESX. I select everything that needed and when I import, I have an error, doesn't matter which option I select or if the VM is running Windows or Linux. Also my ESX are running vmware 5.5.0

Here is the log and screenshot :

@Touille As @florent said in a previous message probably the full SR object is sent to the backend instead of its id. This happens when you change the destination SR from the default one to another. You can try to proceed with the export on the default SR.

Take a look at this branch: https://github.com/vatesfr/xen-orchestra/pull/6696/files
It seems to fix the error.

Hi @ismo-conguairta.
As you and Florent said, before the update, when I tried to import to another SR than the default one, it wouldn't work.

Since the update an hour ago, it's fixed I've just imported a VM from VMware to any SR I want

thank you!!

It may have already been mentioned in here more recently, but I still think some kind of system to select specific VHDs from the ESXi box would be super nice.

Sometimes one may only need to move the data of specific VHDs (excluding say logging or other temporary data style VHDs) and this would greatly speed up migrations.

It would also help in the event someone has VHDs that are larger than 2TiB, since you'd be able to only move the smaller ones and find an alternate solution for the larger than 2TiB VHDs.

Just a thought though; this tool is still amazing and has helped me start migrations!
