Dear,

There is indeed enough memory on the recieving node. We are having nodes with 1TB of memory, and currently they are loaded with around 500GB each. Ill try to reproduce it with a cloned production server. So i can reproduce it a few times with and without network and to a empty receiving node. Ill keep you updated.

I have not tested what happens if i reduce the memory of that VM cause the VM need that amount of memory. I do know that we have around 190 vm's and it only happens with vm's with alot of memory.

Hi Danp,

I am using XCP-NG8.2 latest updates.
The VM OS is in most cases Centos7.9 With guest tools installed.

HI all,

When i do a VM migration from node to node with the use of a shared storage and this vm has more then 24GB of memory it always crashes.
Making a kdump to vmcore-dmesg

This are the lines:
vmcore-dmesg.txt

Anyone knows why this gets triggered? The VM's uses static memory with the same min/max limit. So its not trying to lower the memory before the migration.
Also the VM is not really busy, and is transferred over 10Gbit network in less then a minute.

Kind regards,

Kevin
