Passthrough a disk with an existing Windows 10 installation?

[PonyoHam]

Hi,

How can I pass through my sata ssd with an existing windows 10 installation to a VM in proxmox? I tried following the docs but I get some mapping table on screen that shows a bunch of pciroot sata messages.

Hmm - my first guess is that the pciroot sata messages are more related to the PCI-devices you're trying to pass through than the sata-disk
* do the issues also occur if you remove the hostpciX lines?

if the issue persists - please post the logs containing the messages

if you passthrough a SATA disk - still attach it as scsi (the controller for accessing it is emulated in both cases and virtio-scsi is far faster than the sata emulation)


I hope this helps!

I don't think so, that is my GPU.

Anyway I deleted those entries but no luck. It just doesn't want to boot from my existing Windows install. I tried sata0, scsi5 and virtio. Every time I set the passthrough disk as the boot disk. If I boot from the local-lvm disk I can see and access the passed through Windows disk. I also installed the viostor and vioscsi drivers on the Windows disk I want to pass through. Looks like Proxmox cannot find the boot record?
