Max no of block devices

[erikje]

Hi all, i'm currently running a freenas box with 4 WD disks in a ZFS Z1 config. Works great except i would like to use some other software not available on freenas.
So i thought up the idea to virtualise my machine. Got an 30 gbyte ssd, installed proxmox all running fine.
However.... i want to run a vm with Freenas in order to access my existing ZFS data and provide an NFS share to proxmox for VM storage. As i'm running freenas of an USB stick i made an image of the stick and wanted to attach that to my VM as SCSI disk, no luck so far as i can't seem to boot from SCSI ? Ah wel, just create an virtual HD and install to that, but it seems that the max no of IDE devices is limited at 4, which leaves me no room for an OS block devices (as i need to map 4 IDE drives to the FreeNas VM)

Is there any way to:
*) present my USB stick image as USB strage to the VM and boot from that?
*) increase the number of IDE devices
*) Boot from SCSI

I really do not recommend running storage as KVM, but this is another story. as far as I know freenas does not support virtio for storage devices, so the only change is using scsi, booting should work, see this thread
