Xen users - May 2005 - Problems creating a Xen domain.

Hello,

I installed xen from Fedora rpm. I can boot on Linux version 
2.6.11-1.1286_FC4xen0 and start xen daemon
but when I try to create a domain I always have the same problem . I get 
this message (see below)
about the /lib/tls though I''ve renamed them even in the guest domain. 
When the "Restarting system" message appears the console gets stack. I
leave the console with Ctrl ].
Then the state of this new domain (the one I am trying to create) is
"s"
when I check it with the "list" command.

I attach the configfile, the information about the domain and part of the 
error message.
Could somebody help me ??

Thank you in advance.

Rosa

Hi there!

domain.
I''m not sure moving /lib/tls is supported in FC4 - @Rik, is that the
case?

^ The TLS warning isn''t your problem, it''s this.

You may find this page helpful:

In particular, look at a), the use of MAKEDEV. Do that for the domain''s
filesystem and it should boot.

HTH,
