In case someone ends up here with a similar issue, you also end up at the UEFI shell when UEFI is selected for a BIOS-based image. Try with Advanced -> Boot firmware changed to bios.

Hi, It's a very good question and that's why we are working on our new "Vates virtualization" bundles: basically, you'll have one pricing for the whole stack (both XCP-ng and XOA together). XOA "alone" support doesn't make sense anymore anyway. That's also why XOA as a standalone product (and XCP-ng) will probably get removed in favor of those new bundles. To answer your question on how it works now until the next months: if there's a problem during a backup because your storage, if there message tells "VDI SNAPSHOT FAILED. This is a XCP-ng error", obviously, you won't be covered because it's likely a storage issue, not a Xen Orchestra issue. If you want to have more info on our future bundle pricing, please contact us for an offer on https://vates.tech/contact/
