XCP-ng Center 8.0.0 (build 8.0.0.24) live/offline virtual migration/move

[gorbi13G]

Describe the bug Impossible to do Live or offline migration/move of virtual from one Xen to another one.

To Reproduce Start XenCenter

1. Right click to one virtual
2. While migrating first virtual after XenCenter startup:Select destination Xen, select all necessary options to migrate.. it works
3. While trying to migrate 2nd virtual, when select dest.Xen, button Next is grayed out, not possible to continue

Expected behavior Buttno next should be black and i we can continue with live/offline migration/move of a virtual to another Xen.

I confirm this issue.

I just update my XenCenter and I can't Move/Live Migrate any VM.

You can see the problem described in my screenshot.

Can you confirm it's specific to XCP-ng Center and not the platform? Does it work well in Xen Orchestra?

before upgrade or from another machine where is still XCP-ng Center 7.6.3.21 it is still working OK...

I don't have Xen Orchestra but I can tell you that with another XenCenter 7.6.3, I don't have any issue.

It seems that when we select the destination, a check is made and the "Next" field becomes available if all is OK, obviously on the 8.0.0.24 version, the field remains disabled. This seems to come directly from the interface.

I'd like to have a double check confirmation if possible, in order to triage and make a better diag. You have two options:

• migration using xe in CLI
• Using XOA Free which is pretty straightforward to deploy with a bash -c "$(curl -s http://xoa.io/deploy)" from your host console/SSH

Ok, i will make a migration via CLI and i will post the result to you

Be aware that there is no XenCenter 7.6.3!!!

The version is 7.6.3,and it is XCP-ng Center of course :)

I confirm that the following command work with any issue:

xe vm-migrate vm=xxx remote-master=xxx remote-username=xxx remote-password=xxx vif:xx=xxx live=true

So i thing it's just a bug from the XCP-ng Center.

Thanks for your assistance

100% this is bug of the new XCP-ng Center 8.0.0 (build 8.0.0.24) First migration/movement after application start is working like a charm - button Next is not grayed out. In the second migration is usually the "Next" button grayed out.

Thanks for the feedback lads!

[borzel]

I can reproduce the issue.

[olivierlambert]

I don't get it (reading C# code isn't my main talent). Why it was introduced and why it causes an issue for us?

[borzel]

It's seems to be also an issue in XenCenter 8.0 and only fixed in xenadmin master. It's maybe a regression, but I don't have access to the internal CITRIX isseu tracker, so I can not know what's CA-314346 :-/

[olivierlambert]

haha so it's an upstream bug then :p Nice catch!
