VMware migration tool: we need your feedback!

@olivierlambert Also, do you know if the disk is OVER 2TiB thick provisioned but actual data usage on it is like 1TiB, will the script still fail or will it just create the 1TiB disk?

olivierlambert

The problem by doing that automatically is you can have bad surprises. We'll probably just skip it after adding the option.

severhart

@florent none of the drives are over 2tb, largest is 900GB, so I will assume it is due to snapshots?

Drives are
127GB
900GB
325GB
250GB
500GB

olivierlambert

@severhart as Flo said, it's because of your VMware version (6.5+) that is using another "diff" format not yet supported. In your case, you should do a cold migration for now, until we support this diff format

Total noob here jumping in at the deep end.

I get

Hey @magicker can you give us more details? Are you using XOA or XO from the sources? At which version? Also on VMware side, what's your ESXi version?

magicker

@olivierlambert said in VMware migration tool: we need your feedback!:

XO from the sources

XO from github (2 days old)

esxi .. 7.0.0 (Build 16324942)

olivierlambert

So the diff for warm migration isn't supported on ESXi 7.0 (yet!). So your VM must be halted first (on the VMware side I mean)

florent

hi @magicker

you should also have additionnal logs in your xo logs

Thank you for testing it

regards

magicker

@olivierlambert ah I see.. other than that!! it works.. Just like magic!! v cool

rochemike

Executing the following command resulted in an error until I powered the VM off:

ESXi host ==> VMware ESXi, 6.5.0, 19092475

Any ideas?

olivierlambert

Same answer than my previous post: since ESXi 6.5, there's a new diff algorithm @florent is working on it, but it's even more complicated than the "legacy" one

rochemike

@olivierlambert oh ok, I saw that and thought your comment was specific to the ESXi 7 version.

Thanks for the speedy response. I'd love to know how you clone yourself to be so responsive 24/7. Or am I talking to a Vates instance of ChatGPT?

olivierlambert

Sometimes I wonder But mostly because community is always my priority, regardless the fact we are a company with more than 30 people nowadays (with everything included on what is means).

magicker

new issue.. I am trying to pull a vm (powered off) from a server I have already pulled 3 vms from (no problems)

However, this time it takes a few seconds before the command ends.

I can see the vm however, no disk is pulled over at all.

no obvious errors in logs.

olivierlambert

Weird, you should have at least a reason why it stopped

florent

@magicker
that's a great start that 3 VM goes through without problems
is your esxi still responsive after ? did you retry later ? what are the disks size of the failed vm ?

magicker

@florent Yes, esxi is just fine. All running VMs are happy. I have pulled one more off this server after the failed attempt. Have tried about 6 times .. same result.. VM appears.. process completes after a few seconds.. no disk appears

The disc config seems very boring and normal.

Interested in this. I currently have an entire dedicated server running ESXi solely for the purpose of running a licening server for load balancers. ie lowest of low impact.

Would love to get that into xcp-ng so the server can be used for something else.

florent

@magicker is there any logs on xo-sevrer side ? If you use a xoa, can you open a ticket and a support tunnel ?
