Hi James,
if you want you can review the COMMANDS used by me in order to create
distro, then profile (http://pdcsrv.ece.uprm.edu/blog/?p=78) and then how
to deploy a virtual machine with koan
(http://pdcsrv.ece.uprm.edu/blog/?p=80).
I'm not sure I understand what "distro repository" is in your diagrams
as the cobbler "database" is usually on the same
box.
I see this as:
(cobbler server) <----- pulls data from ---- (target system with koan
installed)
And that's it.
Boot configurations are defined on the cobbler server and accessed
either via PXE or with koan.
Time ago, Michael in private email give a theoretical details about the
roles that plays cobbler and koan, but, since i'm a bad student, i can not
understand all (sorry Michael, but many thanks for your explaination),
however the COMMANDS in those documents, work for me!
Hi Michael, i have a question. According to figure attached, there exist a
machine where is declared a profile->distro->system. If an user is located
to remote server is possible for him execute:
koan --replace-self --server=15.20.10.10 --system=databaseserver
and then, replace the old system for the new one (databaseserver)? What is
the security restrictions to avoid that a malicious user drop a running
system?
The user in question needs to be logged in to the remote system and have
root on it.
(Or, if using "cobbler enchant" needs to be in root's authorized_keys).
Another one, is not possible execute:
koan --virt --server=15.20.10.10 --system=databaseserver
where, in databaseserver system is defined the physical host where the
virtual machine will be deployed? why is that possible considered?
I'm sorry, I don't understand this question.
BTW, best practices for koan suggest using mac addresses for cobbler
system names, not hostnames.
thanks a lot! regards.
