Re: [Xen-users] san fibrechannel device in HVM domU

[Gerhard Possler <gerhard.possler@xxxxxxxxxx>]

hmm....

howmany HBA's do you have in the box?
... because i saw this massage with 2 HBA's with activated BIOS on both
... i think we solved this problem by disabling the BIOS on one HBA, but
i'm not sure anymore. This could be the same problem on Win HVM but you
do have  /var/log/messages on that... You could also run an Linux
in HVM mode but i think you get the same errors.

I just did that, and it starts the PVM domU, well, the driver doesn't load,
because of this error message:

QLogic Fibre Channel HBA Driver

     done
and then on the domU:
lspci | grep Q
00:00.0 Fibre Channel: QLogic Corp. QLA2422 Fibre Channel Adapter (rev

shutting down this PVM, and then trying to start the Windows HVM, produces
the mentioned error message.
