VM's from ESXi, live migration not possible

@OhSoNoob said in VM's from ESXi, live migration not possible:

data-cant-suspend-reason: {"error":{"class":"GenericError","desc":"State blocked by non-migratable device '0000:00:07.0/nvme'","data":{}},"id":"qmp-000253-22"}

Are you using a PCI passthrough or something in the CTX VM? Because that's the issue here: inside the VM, there's a device that can't be suspended.

OhSoNoob

@olivierlambert I am not using any kind of PCI passthrough, but it seems like the storage device for xcp-ng is not using the correct driver.

This is the result of the migrated CTX servers (now using a different server as example, but the result is the same):

With the test server:

however, just changing the storage driver doesn't seem to work. Any experience or tips with this?

Okay so the Xen PV driver for storage isn't working correctly in the problematic VM, so the storage can't be suspended to do a live migration. That's causing your issue

I don't know why the device isn't working correctly (maybe try to reinstall the tools?), but as soon it does, live migrate should work.

OhSoNoob

@olivierlambert The problem with fully installing the tools is our antivirus solution SentinelOne. Simply pausing the agent + reboot gave the XenTools the possibility to install succesfully. After a succesfull installation, enabling the SentinelOne agent again is possible without any other issues regarding the tools or drivers.

Oh great news then!!!

So now you can live migrate and such, right?

OhSoNoob

@olivierlambert Yes! Live migration is now available and working. Which is great!

Excellent news! Thank you very much for the feedback, it might be helpful for others

Enjoy XCP-ng and XO!

Thank you for that find, I was in the same boat.

Oh wow, I couldn't think it would have been helpful that fast!! I think I might update our documentation page about Windows tools and this issue.

Done: https://docs.xcp-ng.org/troubleshooting/windows-pv-tools/#not-all-pv-drivers-are-correctly-installed

Yes, take a look at ticket #7723929. There is also something about shrinking a Windows partition using Linux tools and avoid data loss that could be added to the doc.
