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!

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,
