Yup, tested that and I only spent 1 minute to do the upgrade from 7.5. I had longer reboot time

Yay, looking forward to setting up a mirror.
There seems to be a live migration bug. It happens both with storage migration and between hosts. The VMs migrate to 95% and then it just sits there with network traffic but nothing happening. I also saw this on 7.5 and was hoping 7.6 fixed it.
Does it have to do with the work around for the now closed source citrix packages? -
I also experience this issue randomly
-
This is migrating from local SR to shared SR(Storagemotion)...
The VMs CPUs max out/hang when this happens.
xensource.log while it is hanging constantly repeats the following linesOct 12 15:12:26 xcp-ng-tnogfalp xenopsd-xc: [debug|xcp-ng-tnogfalp|16 |Async.VDI.pool_migrate R:9429eefc8295|xenops] VM = cf2e6622-67c6-682a-4a42-0c1c41c8cb7b; domid = 11; progress = 99 / 100 Oct 12 15:12:26 xcp-ng-tnogfalp xenopsd-xc: [debug|xcp-ng-tnogfalp|16 |Async.VDI.pool_migrate R:9429eefc8295|xenops_server] TASK.signal 193 = ["Pending",0.8999999999999999] Oct 12 15:12:26 xcp-ng-tnogfalp xapi: [debug|xcp-ng-tnogfalp|141 |org.xen.xapi.xenops.classic events D:78feb0765d3f|xenops] Processing event: ["Task","193"] Oct 12 15:12:26 xcp-ng-tnogfalp xapi: [debug|xcp-ng-tnogfalp|141 |org.xen.xapi.xenops.classic events D:78feb0765d3f|xenops] xenops event on Task 193 -

@johnelse will take a look when he can

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.

@rizaemet-0 said in XCP-ng 7.6 RC1 available:
migrate issue with Linux or Windows, PV driver installed or not, vm or storage
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
