VMware migration tool: we need your feedback!
-
@florent Thanks for reaching out
Updated XO from Sources to the commit from the branch.
When I attempt the import from VMware, the process doesn't show an error in the UI and the connect process button looks to spin. However, checking the logs I see the following error (with skip SSL enabled or disabled)
write EPROTO C0F754130E7F0000:error:0A000102:SSL routines:ssl_choose_client_version:unsupported protocol:../deps/openssl/openssl/ssl/statem/statem_lib.c:1987:

@andyh I tried to disable TLS V2, can you
pull --rebase
and retry ?if it doesn't work, could you check the tls level of your esxi host ?

Thanks for the quick response, the same error looks to persist.
Running the curl command gives
* Trying 192.168.xx.yy:443... * Connected to 192.168.xx.yy (192.168.xx.yy) port 443 (#0) * ALPN, offering h2 * ALPN, offering http/1.1 * successfully set certificate verify locations: * CAfile: /etc/ssl/certs/ca-certificates.crt * CApath: /etc/ssl/certs * TLSv1.3 (OUT), TLS handshake, Client hello (1): * TLSv1.3 (IN), TLS handshake, Server hello (2): * TLSv1.3 (OUT), TLS alert, protocol version (582): * error:1425F102:SSL routines:ssl_choose_client_version:unsupported protocol * Closing connection 0 curl: (35) error:1425F102:SSL routines:ssl_choose_client_version:unsupported protocol
Performing the same check with -tlsv1.0 gives

Not sure if this helps.

Hi!
I am having a similar problem to @andyh
Our VMWare is v5.5, xoa CLI throws:"result": { "message": "Client network socket disconnected before secure TLS connection was established", "name": "Error", "stack": "Error: Client network socket disconnected before secure TLS connection was established\n at Function.AxiosError.from (/opt/xo/xo-builds/xen-orchestra-202306231640/node_modules/axios/lib/core/AxiosError.js:89:14)\n at RedirectableRequest.handleRequestError (/opt/xo/xo-builds/xen-orchestra-202306231640/node_modules/axios/lib/adapters/http.js:591:25)\n at RedirectableRequest.emit (node:events:527:28)\n at RedirectableRequest.patchedEmit [as emit] (/opt/xo/xo-builds/xen-orchestra-202306231640/@xen-orchestra/log/configure.js:52:17)\n at ClientRequest.eventHandlers.<computed> (/opt/xo/xo-builds/xen-orchestra-202306231640/node_modules/follow-redirects/index.js:14:24)\n at ClientRequest.emit (node:events:527:28)\n at ClientRequest.patchedEmit [as emit] (/opt/xo/xo-builds/xen-orchestra-202306231640/@xen-orchestra/log/configure.js:52:17)\n at TLSSocket.socketErrorListener (node:_http_client:454:9)\n at TLSSocket.emit (node:events:527:28)\n at TLSSocket.patchedEmit [as emit] (/opt/xo/xo-builds/xen-orchestra-202306231640/@xen-orchestra/log/configure.js:52:17)\n at emitErrorNT (node:internal/streams/destroy:157:8)\n at emitErrorCloseNT (node:internal/streams/destroy:122:3)\n at processTicksAndRejections (node:internal/process/task_queues:83:21)",
While webUI stucks on "Connect" with no apparent logs present..
When checking tls level of my esxi host:
localhost:~ # openssl s_client -connect www.google.com:443 -tls1 CONNECTED(00000003)
Will there be a support for older versions of ESXi? Or maybe I am doing something wrong. Thanks in advance!

@akaylee we brole rejectUnauthorized ( handling of self signed certificate) During the upgrade of node-vpshere-soap, the fixes are coming and it should also work on 5.5
the first one have been merged and should allow you to list the VM on the host. Does it work ?
-
@florent it doesn't seem to work, still stuck on 'Connect', 20 minutes elapsed
-
@akaylee what is your current commit ?
this is the right one : 0f0c0ec -
@florent sorry, overlooked!
Yes, I was able to connect to my esxi host after updating to 0f0c0ec, testing migration right now
Thank you! -
@florent Just updated from sources, but my latest commit looks to be 0f0c0ec0d. Have I missed something ?
-
@andyh that's ok, I only pasted the start of the hash
As long as you're up to date on master, it should work (also it does not disable certifictae check for the whole process now )
-
@florent I still look to be receiving the same error, after updating to 0f0c0ec
write EPROTO C0D7ADA7B77F0000:error:0A000102:SSL routines:ssl_choose_client_version:unsupported protocol:../deps/openssl/openssl/ssl/statem/statem_lib.c:1987:
Any further thoughts?
- 3 months later
-
Gave this is a try earlier with some changes to my openssl.cnf
Sadly still coming across the same error, is there a minimum ESXi version that the import tool will connect to ?

Hi!
I did try the migration from the GUI for the first time.
The job did start and create a VM on XCP-ng. But there is no snapshot on the "VMWare-side" and there is no progress on the import.The job did start and XO-tasks is now showing "importing vms, duration a few seconds, status green"
There is no "cancel" option.
On the XCP-ng-SR, there are the new disks, but they are empty.
Do you have any idea, what I did wrong and how I can proceed?
Tested on XOA on latest stable
Thank you and best wishes
-
@KPS is there anything in the log ( journalctl ) ?
we can't migrate live data. Is the VM running ?
-
@florent
Sorry, that was the problem.
I was mislead by the wording "Source VM stopped before the last delta transfer (after final snapshot). Needed to fully transfer a running VM" in the GUI. -

Hi!
I am still struggeling with the VMWare migration tool.
According to the docs, it should be possible to "warm-migrate" a VM, but when I try to, I am getting errors:
"message": "500 Internal Server Error https://vcenter/folder/InetTS00_U20.04/InetTS00_U20.04-flat.vmdk?dcPath=HZ&dsName=OpenE-2_vmware-1_LUN2",
What is the "right" way to migrate a running VM?
-
@KPS It should, but there are some case where the esxi lock all the files of a VM, and other where it only locks the last snapshot. We're still working on the exact limit, what is the version of esxi used ? what storage do you use ( local VMFS, iscsi, NFS, ... ) ?
In parallel we're putting the finishing touch of a huge change that give a big speedup. that way the penalty of stopping the VM will be lighter. You can test by switching to the branch xva_generation
https://github.com/vatesfr/xen-orchestra/pull/7323 -
@florent
Thank you for your answer. I am using vSphere 7 with iSCSI-storage.
Can you give me a hint on the "most stable" way to migrate? -
@KPS the most stable is always to stop the VMs
Trying to warm migrate a running VM between different hypervisor is always tricky, if not brittle, and we work to harden this process, define more clearly the limits and extends the possibilty (for example vsan)What are the rough sizes of the VMs ? how many VM ? What is the timeframe of the full migration ?
Do you think you can give a try to the xva import on a stopped VM ? on some of my tests, this migration is completely saturating my network link and my disks, as shown in the PR. The fastest way is to have the XO doing the migration directly in the ESXI. As an additional bonus, the disk produced is thin

When migrating VMs from ESXi, the CPU count and Memory allocation is taken over to XCP-ng.
That's all fine for me.
However, after import, the static min memory allocation cannot be reduced.
Is there a workaround?[02:56 xcp01 ~]# xe vm-param-get uuid=... param-name=memory-static-min
8589934592
[02:57 xcp01 ~]# xe vm-memory-static-range-set uuid=... min=4294967296 max=8589934592
The dynamic memory range violates constraint static_min <= dynamic_min <= dynamic_max <= static_max.
