VM for my new TrueNAS server and I decided to passthrough the onboard SATA controller to the VM. I have 4 SATA ports on the onboard SATA controller and I have a 2 port PCI SATA expansion card, which I have connected an SSD to, for installing Proxmox.The
ids I'm using here are not real, just an example.I edited
/etc/default/grub and added,
Code:
GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on iommu=pt vfio-pci.ids=1234:5678,4321:8765"Then, I added these modules to
/etc/modules
Code:
vfio
vfio_iommu_type1
vfio_pciThen, I added this to
/etc/modprobe.d/iommu_unsafe_interrupts.conf
Code:
options vfio_iommu_type1 allow_unsafe_interrupts=1Then, I added this to
/etc/modprobe.d/vfio.conf
Code:
options vfio-pci ids=1234:5678,4321:8765Finally I update the
GRUB configuration and initramfs
Code:
update-grub
update-initramfs -u -k alland rebooted. I could not blacklist the
ahci driver as the PCI expansion card also uses that.After rebooting, the onboard
SATA controller was still using ahci driver and I could still see the drives in Proxmox. However, I noticed, when the TrueNAS VM is started, it shows its using vfio-pci driver, but when its not started it uses the ahci driver. So I search online and found that I could add a softdep, so I added this to /etc/modprobe.d/ahci.conf
Code:
softdep ahci pre: vfio-pciThen, I rebuilt the
initramfs and rebooted again and now I have the vfio-pci driver loaded for the onboard SATA controller from boot, so Proxmox could not see the drives anymore from startup, which is good I think, as I have heard Proxmox taking over the ZFS pool, corrupting the data, for people who have similar setup where they virtualize TrueNAS.So my question here is, is this passthrough thing safe/stable to use? Could it break on any future updates to Proxmox or something else, where its not able to passthrough any more and Proxmox takes over the pool or something?
