Thanks Erwan. since all partitions or raw disk on the domu use blkfront driver, I don’t see where the conflict is. Did you mean the domu would use scsi driver for its mapped partitions or disks from dom0?
Thanks,
Huaxiang

Subject: Re: [Xen-users] disk devices are always /dev/xvdX
As i had time to lose, i tested it and... it works :)
Well at least , it seems to work, the VM launch and i see no errors
be carfull to not use scsi_mod in the same time.

To change it, I think you can try to change this line in the kernel source : drivers/block/xen-blkfront.c
#define DEV_NAME "xvd" /* name in /dev */
But i think there is a good reason to it,
probably to avoid conflicts with the scsi driver,
so i'm waiting for your feedback :)

Hi gurus,
The page
http://wiki.xensource.com/xenwiki/XenParavirtOps says disk devices on domu are always /dev/xvdX. And I failed when I try to map a raw disk to domu with the name /dev/sdb. The line ‘phy:sdb,sdb,w’ in domu config file doesn’t take effect. Actually I found
a raw disk named /dev/xvdf on the domu.
Anybody got any idea why xen4 put such restriction? How to map to other names such as /dev/sdb on domu?
Thanks,
HUAXIANG FAN
