[et-mgmt-tools] what happen? :(

Fri Mar 30 18:26:21 UTC 2007

Hi Michael, i'm sending your response to fedora-xen mailing list for any
comments from them.

About your answer, the machine where i want to create a new virtual node
is the 136.145.116.76. This machine has two virtual nodes up and running,
so i think that message is not a hypervisor problem, the hypervisor is
working.

The other hand, last week i create two additional virtual nodes, in that
machine (116.76), the problem appear today.

Asides, the distro and profile configuration keep the same.

I can't understand why today, provisioning with cobbler stop to work.

Thanks a lot to fedora-xen mailing list for your comments and thanks Michael.
