[Xen-users] Problem importing virtual disk

[Errol Neal <eneal@xxxxxxxxxxxxxxxxx>]

Hi. Let me know if I should be reporting this elsewhere for reasons that I'm 
about to detail below.

I'm fiddling with Xen 4.1.1 on Debian squeeze running kernel 3.0. I was really 
exciting about the Kronos project bringing the API to Debian/Ubuntu so I 
thought I'd give it a try.  

I'm find myself facing a number of challenges working with a local lvm based 
SR. Trying to outright create one, I kept getting errors.. but I was able to 
work around it using the sr-introduce workaround. Now i'm trying to import a 
raw disk image  using the command xe vdi-import and i'm getting a very nasty 
error:

root@squeeze:~xe vdi-import uuid=6d028ae2-a8be-403a-98ae-a02e498af3a0 
filename=c2_appliance.disk.xm

  File "/usr/lib/xen-common/xapi/sm/blktap2.py", line 247, in __list
    key, val = field.split('=')

I haven't tried this with a ext type repository yet, but I think I will soon do 
so. Is what I'm trying to do expected to work?
