[Xen-users] Unable to start xend

[Forest Belton <fbelton@xxxxxxxxxxxxx>]

Hi,
  I'm trying to install Xen on Ubuntu 11.04. I read somewhere (please 
correct me if this is wrong) that Ubuntu hasn't had dom0 support since 8.04 
LTS, and the recommended action was to grab a dom0-enabled kernel from 
Debian, so I did. I'm running 2.6.32-5-xen-amd64 and built Xen 4.1.1 from 
source. After installation and some troubleshooting, I tried to start xend. 
Here is the result:
vmtest@morphy:~$ xend start
xc: error: Could not obtain handle on privileged command interface (2 = No 
such file or directory): Internal error
Traceback (most recent call last):
  File "/usr/sbin/xend", line 36, in <module>
    from xen.xend.server import SrvDaemon
  File 
"/usr/local/lib/python2.7/dist-packages/xen/xend/server/SrvDaemon.py", line 
26, in <module>
    import relocate
  File

    from xen.xend import XendDomain
  File "/usr/local/lib/python2.7/dist-packages/xen/xend/XendDomain.py", 
line 36, in <module>
    from xen.xend import XendOptions, XendCheckpoint, XendDomainInfo
  File "/usr/local/lib/python2.7/dist-packages/xen/xend/XendCheckpoint.py", 
line 20, in <module>
    from xen.xend import balloon, sxp, image
  File "/usr/local/lib/python2.7/dist-packages/xen/xend/image.py", line 46, 
in <module>
    xc = xen.lowlevel.xc.xc()
xen.lowlevel.xc.Error: (1, 'Internal error', 'xc_interface_open failed: No 
such file or directory')
Some searching led me to believe that this error occurs when I haven't 
booted into a Xen kernel, but this confuses me as I am fairly certain I 
have. /sys/hypervisor exists as well as /dev/xen. What have I overlooked? I 
apologize in advance if I have posted to the wrong mailing list.
Sincerely,
  Forest
