I''ve been reworking my Xen setup again, and am having problems adding an AOE (ata over ethernet) device to a domU. If I assign the /dev/etherd/e1.0p1 directly to the domU, I get this error: root@sol:/dom/luna# xm create luna.conf -c Using config file "luna.conf". Error: Adding extent to vbd failed: device (vbd (uname phy:etherd/e1.0p1) (dev sda1) (mode w)), error 8 root@sol:/dom/luna# Here is the disk line from my luna.conf: disk = [''phy:etherd/e1.0p1,sda1,w'', ''phy:etherd/e1.0p2,sdb1,w''] I noticed my e1.0 devices have a minor greater than 255: brw-rw---- 1 root disk 152, 256 Feb 3 08:04 e1.0 brw-rw---- 1 root disk 152, 257 Feb 3 10:21 e1.0p1 brw-rw---- 1 root disk 152, 258 Feb 3 10:21 e1.0p2 I made a test e0.0 device to test the theory: brw-rw---- 1 root disk 152, 0 Feb 3 11:30 e0.0 brw-rw---- 1 root disk 152, 1 Feb 3 11:30 e0.0p1 And I can assign that without problems. My AOE minors go well up into the thousands - is there a workaround?

Forgot to mention, I''m running Xen 2.0.7.

I think it would break the 2.0 I/O interfaces anyway, as the 8+8 major/minor split is baked into the control interfaces. PCI passthrough will be in 3.0 series within a week or two. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
