Manually select boot device every reboot after pcie sata controller passthrough

[lxiosjao]

Hello,

Since I passthrough my sata controller to my ubuntu-server VM, I have to manually select OS disk in the console every reboot of the vm.
In the boot option (GUI proxmox) there is only the possibility to put the pci controller first (but not the disk).
Any idea how am I supposed to do it automatically ?

Thanks for your help

Why is it important ?

If you passing through the firstt sata controller, it's hard for your host if you cut is disk access... You need to be sure that (in mind....) you've passed through the nordbridge sata controller. The south bridge is used by default by Host.

okey
Used for the host :
1. Sata controller Intel : proxmox

Used for the guest :
2. Sata controller Marvell (guest) --> passthrough : SSD with ubuntu-server + HDD disk (zfs)

How can I check if the Marvell is the northbridge sata controller ?
The intel is necessarily the southbridge, right?

Is your Marvel controller PCI card? If yes or no,check that xD : https://forum.proxmox.com/threads/trying-to-pass-through-a-sata-controller-on-the-motherboard.99192/

You need to blacklist your Marvel controler for stop his use by the host

PS: don't recover my sata controller documenttation... ^^ Ask to google

The Marvell controller is a chip on the motherboard.
I'm going to check that, thanks

edit : Can you help me to blacklist for stop his use by the host ?

I know how to make that for a GPU, but never done for another chipset type.

I drop you the how to for a GPU:
https://pve.proxmox.com/wiki/Pci_passthrough

I think theses points interrests you:
- "2." Check for your CPU model
- "4." Preventing bad shutdown caused by shutdown by a VM
- "6,7,8"

Other points are really specified for GPU passthrough ^^" But, you're not passtroughing a GPU card, blacklisting is'nt maybe necessary.

EDIT: after found this older post, it's seems you need to enable vfio modules :

It's seems it's a complete topic, wich you can solve your problem

The passthrough seems to be ok from the vm.

06:00.0 SATA controller : Marvell Technology Group Ltd.  SATA 6Gb/s Controller  (rev 11)
    Subsystem: Computer Inc.  SATA 6Gb/s Controller ]
    Kernel driver in use: vfio-pci
    Kernel modules: ahci

SeaBIOS ( version .........)
Machine UUID ................
No bootable device. Retrying in 1 second.
Rebooting

But I still have to select the OS SSD in the console GUI when the VM reboot :-(
(press ESC for boot menu and press 1 to select the OS disk)

Can you share the tab Options of your VM ? And can you check how the VM boot ?

Here is the option tab of the vm
How can I check how the vm boot ?

I dont know why but its solve since I changed the bios from SeaBIOS to OVMF (UEFI)..
