This creates megasas device in the guest, but it does
not work still, at least with the debian wheezy (current)
kernel. It tries to load megaraid_sas module, and is
getting this:
scsi3 : LSI SAS based MegaRAID driver
irq 22: nobody cared (try booting with the "irqpool" option)
...
--- Exception: 501 at __do_softirq+0x6c/0x1dc
LR = call_do_softirq+0x14/0x24
...
--- Exception: 501 at megasas_fire_cmd_ppc+0x28/0x2c [megaraid_sas]
LR = megasas_issue_dcmd+0x28/0x38 [megaraid_sas]
...
Disabling IRQ #22
scsi 3:0:0:0: megasas: RESET cmd=12 retries=0
megasas: [ 0]waiting for 1 commands to complete
megasas: [10]waiting for 1 commands to complete
INFO: task modprobe:4017 blocked for more than 120 seconds.
...
and so on.
So I'm afraid megasas isn't exactly useful in this situation.
Thanks,
