@MathieuRA Confirmed, looks good! Thanks.

@olivierlambert Ouch, I'm running PV guests everywhere when I use NetBSD which was ideal system both for DOM_0 and DOM_U back in the days. It migarted with no issues to Citrix Xen 6.5 then to 7.0 then to XCP-NG up to 8.2.1. Standards are changing I guess. If its not something that could be fixable now, I will start thinking of migrating to HVM to be ready for 8.3 release. Thanks.

@olivierlambert Indeed, changed from DR to CR and is going without issues, nice. Thank you!

I tried to do Disaster Recovery Backup from VMs running on 8.3 beta2 to host running 8.2.1 with Xen Orchestra from sources (newest build), and this job ends with this error below.

Is this supported - 8.3 to 8.2.1 DR Backup? Or something else is wrong here.

Hi, I don't know if this is correct category, hope it is.

So I have bunch of perfectly running PV machines on XCP-NG 8.2.1 for years.

I wanted to test 8.3 beta2 and migrated, or I should say - created new one on 8.3 from snapshot on 8.2.1 from Xen Orchestra.

Every VM that is created eventually on 8.3 wont starts because of the error:

INTERNAL_ERROR(xenopsd internal error: Domain.Domain_build_pre_failed("Calling 'shadow_allocation_set 9 MiB' failed: Xenctrl.Error("22: Invalid argument")"))

Amount of ahadow_allocation can vary - sometimes is 10MiB.

Migrated VM is small - 1 CPU 1 GB RAM, 10GB HDD.
I tried changing RAM and CPU, but that didn't change anything.

However detatching disk gives - INTERNAL_ERROR(there is no bootable device), attaching it back and set bootflag to on, gives original error again.

Below is log from SMlog when trying to start this machine, but I can't see any problem there:

@olivierlambert Thats the limitation I'm aware of. But in my case - HomeAssistant VM with three USB passed trough (zigbee dongle, z-wave dongle, USB cable to UPS), I'm relying mostly on HA internal backup, and one basic snapshot, so I don't need snapshots on daily basis

@borzel Thank you for great work! USB pass-trough GUI from XCP-NG Center will be missed - this is one single feature I'm missing from XO and XO-Lite, that XCP-NG Center addressed very well.

@MathieuRA Confirmed, looks good! Thanks.

@cleverit did you manage to fix it? Same issue on xo-server 5.102.0. Once enabled and failed, no matter what I do with turning it on and off and saving both schedule and job it still wants to run.

@olivierlambert Thanks a lot. Updating

@Danp Thanks for the update on this, I will follow it on XO github as well
