Followed a webdevster How to install Xen 4 on Debian 6 Squeeze x64 tutorial
Everything went textbook, until the reboot into the new XEN kernel.
Tried booting in the following order from grub to see which one fails
Debian GNU/Linux, with Linux 2.6.32-5-amd64
Debian GNU/Linux, with Linux 2.6.32-5-xen-amd64
Debian GNU/Linux, with Linux 2.6.32-5-xen-amd64 and XEN 4.0-amd64
with quiet passed to kernel
Failed to setup GSI
with verbose passed to kernel:
Write cache: enabled, read cache: enabled, doesn't support DPO or FUA
ata3: lost interrupt (Status 0x50)
sd 2:0:0:0 [sda] Unhandled error code
sd 2:0:0:0 [sda] Result: hostbyte=DID_OK driverbyte=DRIVER_TIMEOUT
sd 2:0:0:0 [sda] CDB: Read(10): 28 00 00 00 00 00 00 00 08 00
end_request I/O error on device sda, sector 0
Buffer I/O error on device sda, logical block 0
It then appears to continuously loop through trying the disk, failing and trying again, slowly counting up through the sectors and blocks, failing and going round again.
I assume I've missed something, I've re-read the tutorial, don't think I've missed anything maybe XEN treats disks differently, however I'm at a loss, any help appreciated.
