XCP-ng 7.6 RC1 available
-
I also experienced this a few times with XCP-ng 7.5.
In one case (Windows VM) a process in Windows was on 100%, after I killed that process, the VM spontaniously migrated... till the process killing the VM was very slow, was a pain to get pass the login screen and start the taskmanager.
So I expected old PV drivers to be the reason. After upgrading the PV Driver (with latest package from Citrix) the issue went away for that VM ... but I did not test this further because it was on a productive pool.

I've had this happen migrating the XOA VM.
I also have it happening on some linux VMs that don't have any tools installed. -
I also experience this migrate issue with Linux or Windows, PV driver installed or not, vm or storage live migrate. Ramdomly as @olivierlambert said. Not always.
-
I just updated the first message to add a note for those who want to update their 7.6 beta to 7.6 RC1.

I can reproduce on my end almost every time. the migration hangs more often than not.
-
Anything in logs that could help us to track down the issue?
-
I haven't seen much, but I am curious about my post earlier about xcp-emu-manager, I see emu-manager referenced in the logs and was curious if xcp-emu-manager should be referenced.

I did a test. Tried a storage live migrate on a vm which have one sanpshot. And cause this migrate problem. stack in 99%.
Then I delete snapshot of this vm and wait coalesce process. then tried again storage live migrate. Successfull.
I did this test on same vm. so, for now I think problem source is look like snapshot. I will do more test. -
On 7.6, right?
-
@olivierlambert Sorry, maybe not right topic for this issue but my xcp-ng is 7.5
-
Okay so it's not the right topic indeed, but I really want to know if you still have these issues on 7.6 RC
-
@olivierlambert I will try and will post result
-
Thanks a lot! It's important to test between 2x 7.6 hosts, to be sure it's still an issue and not a problem from another version in the middle

Mine is between multiple 7.6 hosts. PV tools, no PV tools, linux, windows. It all does it.
-
@conradical vm have any snapshot what you try to migrate? is this storage live migrate or vm live migrate?
-
@rizaemet-0
No snapshots. It happens on both storage migrate and love migrate. -
Any activity in the VM or it's idle?
Are they in the same pool?
-
@olivierlambert
Same Pool. It does not seem to matter if it is idle or not. -
Interesting update: I installed the latest PV tools by enabling window update, this fixed 4 out of my 5 test VMs running windows. More testing is underway with linux PV and HVM.
-
That's maybe the reason why I can't reproduce. It's like old tools will lead to migration problems but not more recent ones
