@MathieuRA Thanks for doing the fix, I have tested this and I confirm it is working. I am able to migrate VMGuest to a different host by ticking the check box in the vmlist.

@olivierlambert Oh, I misread the documentation. Thanks anyway for answering my question.

I've had something similar in the past and if I recall correctly I had to go into the guest and disable it's network adapter, then make the change on the host, then re-enable the network adapter in the guest VM. Might be worth a shot to see if that solves it. I believe with the Citrix drivers though it doesn't happen.

@splastunov Great idea! Thank you!

@olivierlambert I do not understand wha t you mean by "You probably need to transform the disk in a "regular" and not snapshot". Not sure on how to do that, please provide the steps or if you have SOP ready, please point me to the SOP document.

@olivierlambert Oh I see, thanks for the help.

Okay so that's fine on this side.

@olivierlambert Yes, thank you so much for the big help.

@olivierlambert Thank you for sharing that information, that is an additional knowledge for me.

@MathieuRA Indeed, that's the right way to do it, I think

@stormi Thanks for the big help that fixed the issue.
