    After performing the following commands on the latest 8.10 Desktop 64bit:
    Code:
    sudo aptitude install ubuntu-xen-server
    sudo apt-get install xen-tools
    sudo reboot
    
    The Xen kernel does not load:

    Code:
    admin@356835794:~$ sudo xm list
    ERROR Internal error: Could not obtain handle on privileged command interface (2 = No such file or directory)
    Traceback (most recent call last):
      File "/usr/sbin/xm", line 8, in <module>
        from xen.xm import main
      File "/usr/lib/python2.5/site-packages/xen/xm/main.py", line 61, in <module>
        xc = xen.lowlevel.xc.xc()
    xen.lowlevel.xc.Error: (1, 'Internal error', 'Could not obtain handle on privileged command interface (2 = No such file or directory)')
    adminuser@356835794860:~$ sudo uname -r
    2.6.27-7-server
    admin@356835794:~$ 
    

    Does anyone have an idea why?

    On Ubuntu 8.10, the Xen kernel is only for domUs, but not for dom0 - there's no dom0 kernel because the Xen project didn't create any patches for the latest kernels... :(

    Yeah, figures...

    It's alright though, that VirtualBox works great. Very impressed with it, took me all but 10 minutes to get that going :)

    Having the same issues!

    Hey!

    I need some help on this. I am running:

    Ubuntu 9.10 and
    Kernel 2.6.31-15-generic-pae

    When I try to run any xm command, I have the same error as mentioned above, namely:

    pbhat@pbhat-acis:~$ xm list
    ERROR Internal error: Could not obtain handle on privileged command interface (2 = No such file or directory)
    Traceback (most recent call last):
    File "/usr/sbin/xm", line 8, in <module>
    from xen.xm import main
    File "/usr/lib/python2.6/dist-packages/xen/xm/main.py", line 61, in <module>
    xc = xen.lowlevel.xc.xc()
    xen.lowlevel.xc.Error: (1, 'Internal error', 'Could not obtain handle on privileged command interface (2 = No such file or directory)')



    I understand that my kernel not being able to support Dom0. However I do not know how to go about solving the problem. Could someone elaborate on where I need to put the earlier kernel (hardy) version so that dom0 can use it to boot and which files I need to edit?

    Thanks
