  • Thread-topic: [Xen-users] Storage for DomU

 I tried with the 'lspci' but it doesnot give any output.
I tried to load the driver (QLA2200, Qlogic FC HBA) but this driver is
only for RH and suse Linux not for Slackware.Any idea. 
I also have another VM installed on the same host with RHEL. But
changing the config file present at /SRxxx/SRM/configs doesnot show this
pci Device in the 'xm list -l' output.
Can I do something for this RHEL DomainU?

Thanks and regards

"lspci" should show this device and not much else in your DomU (as
DomU's can't see devices that haven't been given to them, it will only
show [I think] a few "fake" devices that Xen uses for it's drivers). 

The other idea is of course to load the correct driver for the device
(e.g. modprobe drivername). I don't know what the name of the driver is,
but it should work.
