[one-users] can't get s information from the physical node

Hi, Matheus

Thank you very much for your solution. I have followed with your method, it still didn't work for me. Otherwise I don't use Xen but KVM, so I add all the KVM related files to /etc/sudoers:

oneadmin ALL= NOPASSWD:/usr/sbin/kvm
oneadmin ALL= NOPASSWD:/usr/sbin/kvmctl
oneadmin ALL= NOPASSWD:/usr/sbin/kvm-img
oneadmin ALL= NOPASSWD:/usr/sbin/kvm-nbd
oneadmin ALL= NOPASSWD:/usr/sbin/kvm-ok
oneadmin ALL= NOPASSWD:/usr/sbin/kvm_stat
oneadmin ALL= NOPASSWD:/usr/sbin/kvmtrace
oneadmin ALL= NOPASSWD:/usr/sbin/kvmtrace_format

But there is another point that I can only ssh from front-end to my remote node without password, but I can't ssh from my remote to my front-end.
I think this is the reason that the remote node can't send the KVM information back to the front-end. Is right?

Any other ideas?

I had this same problem, that was resolved when I gave some root access to
my oneadmin account. In my case I had to add two lines to the  /etc/sudoers
file, as follow.

oneadmin ALL= NOPASSWD: /usr/sbin/xm
oneadmin ALL= NOPASSWD: /usr/sbin/xentop
