Hello,
I have an issue with my XEN system. I suspect that it might be a bug,
but I''m no linux expert, so I don''t know. Here is my problem:
I have an
ASUS P7P55D-E Premium motherboard, and a Western Digital Caviar Black
SATA-III 1TB hdd. I am trying to use AHCI. The dom0 is an Arch Linux.
The dom0 boots fine until Intel VT-d is enabled in the BIOS. When I
enable it Arch Linux still boots fine, but XEN with the Arch Linux Dom0
fails to detect the hdd (the /dev/sda node doesn''t exist), and drops me
into a recovery shell. I have upgraded to the latest BIOS version, but
it still fails.
My XEN version is: 4.0.1
My Arch Linux dom0 kernel version is: 2.6.34-dev (2.6.32 also fails)
(Probably) relevant lines from dmesg:
