I have a PCI-E Dell Perc 6/i RAID card that I'd like to flash with the latest firmware. Apparently I need either a Redhat / Centos OS or Windows in order to flash the firmware, but I have a VMWare 5.0.1 ESX hypervisor installed on the box and a CentOS guest OS. My motherboard support IOMMU and I have successfully used VMWare's PCI Passthrough feature to give VMs exclusive access to a PCI-E device. Is it safe to flash the firmware of a PCI-E device if that device is passed through to a single VM using the passthrough feature of VMware? Or should I boot one of the supported OSes directly on the bare metal?

If that RAID card is in use by the host you could have some... Undesirable effects on the host when you disconnect it (speaking from experience here, I still have an orphaned VM that I can't shut down because of unexpected removal of storage) –  Mark Henderson Sep 26 '12 at 2:09

Yep. Doable... I needed to do it with an LSI 9211-8i controller enabled through passthrough.
