[Xen-users] Error: (2, ''No such file or directory'')
I am completely new to Xen. Trying to run it on a Kubuntu Dapper with
packages and kernel from debian.thoughtcrime.co.nz.
When I try to start a domU with
xm create -c /etc/xen/vm01.cfg
it says:
Using config file "/etc/xen/vm01.cfg".
Error: (2, ''No such file or directory'')
I expect it to be a very simple problem, but do not know where to start.
/var/log/xend.log says

If xend _isn''t_ running then do `/etc/init.d/xend start` and give vm01 another try.

There is another reply with a fix. I would suggest you add it to your init.d such that the directory is recreated before the "xend start" happens. That way if you upgrade Xen and it rewrites all your Xen-related scripts, it doesn''t wipe out the fix. xend really ought to create the directory itself... -- Andrew Thompson http://aktzero.com/ _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
