Q1. Yes. IB & IR share the same principle.
Q2. Key backups are a plus to be on the safe side, but it's not the only way to do it. You also have backup health check, as you suggested. To me, it depends on the criticality of your data. To me, health check after 20 IR isn't bad but it's really a "personal" choice

Hi,
IIRC, the scheduler is smart, if it's using the same time, it will reuse snapshots as possible. @florent could give more details when he's around

RE: Intel Flex GPU with SR-IOV for GPU accelarated VDIsposted in Hardware
If you are that much confident, then feel free to purchase one and use it: XCP-ng supports SRIOV but for NICs, I don't know how different it could be for a GPU, but without any hardware to test it's impossible to answer. How difficult it was to work on a more simpler hypervisor (KVM) doesn't send encouraging messages though.

Sure, but if it's 6 months of work with 3 engineers, this means it's not "free" and you need enough resources to do it. So if people want something like this, we need to get at least some traction and a way to know how much work will be involved
edit: obviously, if it's plain SRIOV without any special work, it's another story.

If it really requires a 6.x kernel, this will at least wait for XCP-ng 9
And regarding the demand, you are officially the first to ask for it

RE: VMWare import with UEFI failsposted in Migrate to XCP-ng
There is something special about this VM, it's seeking for a device that's not here anymore, now the question is which device
Have you tried to remove the VMware tools in case they are doing something funky?
