March 15, 20224 yr Hello, I have a VM to which I pass an NVME drive. It boots ok from it as long as it is the only drive. However, I would like to associate to the VM also a SATA drive which, being the only sata drive, it is always seen as the primary disk and the VM tries to boot from there. How can I change the behaviour so that I can boot from the nvme drive?

March 17, 20224 yr In addition add boot order=1 inside your nvme block, for example: <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x19' slot='0x00' function='0x0'/> </source> <boot order='1'/> <address type='pci' domain='0x0000' bus='0x05' slot='0x00' function='0x0'/> </hostdev> Note that this is valid only if your nvme controller is at 19:00.0, otherwise, edit the correct block. I think that sata has boot priority over a vfio nvme drive. If it still doesn't work press esc when the vm boots to enter ovmf bios setup and change boot order there.

Entering the ovmf bios setup works, I will try your other option, thank you for your help in the meantime, I will post the update.
