Thanks @lawrencesystems - I've finally got around to watching that video, explains the content well, quite interesting to see that happening in real time when the RAM is being land-grabbed by other VMs when things are getting full based on the different configuration settings.

@MichaelCropper That's awesome! I'm glad the usual computer pixie dust fairies dropped by and fixed the issue for you. Poor Windows though... you initially laid the blame at their feet, but it seems more like this was a Google Chrome issue. I've noted a LOT of peculiarities with Google Chrome as of late and have started to migrate away for that reason. Reading a lot of forums on Reddit and other IT sources, this seems to be something that is pretty wide-spread. In any case, it's working for you now... until Google changes something again. LOL I hope you have a great weekend!

There's no black magic As @ronivay said, you need to tell the filesystem inside your VM that the disk grew. On Cloudinit-enabled VM, there's an auto-grow parameter that is checking at each boot if the disk was extended, and will automatically do it for you. But again, that's inside the VM. Keep in mind: it's not the job of the virtualization system to deal with what's inside the VM

As stated in the big warning yellow box here in the official doc: https://xen-orchestra.com/docs/community.html#report-a-bug Closing then

anyone who solved this problems, could you share how to solve the bug? xen 8 with xcp ng centre 20 could not run autostart vm
