[Users] How to migrate the Ovirt management server/frontend to another machine ? (what files are needed, etc)
Hi. As we are using Fedora16 as the OS on the frontend I would like to know what files/DB's, etc are needed to migrate the management server/frontend to another machine? I ask as the support life of Fedora is not too long, so for example when FC17 is released I would like to migrate the machine to that - by migrate I mean backup and re-install. Is there any info anywhere showing what files I would need to migrate/backup to a new frontend server? - I assume its going to be a DB and several files - I would just like to know for sure. Ovirt looks really nice btw - thank you to all who made this possible. As a 2nd question - is there an ETA from when RHEL packages are going to be ready? Many regards ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Hi,
I am new to ovirt and LDAP. Looking at adding support for Tivoli
Directory Server. Here is a small java/jndi program (not using Spring
LDAP) that takes IBM intranet Id and searches the directory to return
IBM serial number.
Hi Sharard, welcome aboard.
First of all, although this can be found in our mailing list, I would
like to point you that currently Roy Golan (rgolan at redhat dot com),
Oved ourfali (ovedo at redhat dot com) and myself are the people that
work mostly on ldap/authentication issues at engine-core - so feel free
to ask us questions.
In addition, I would like to give you a WIKI to help that will give you
some getting started info (This WIKI was written by Oved) -
http://ovirt.org/wiki/DomainInfrastructure
Yair, Thanks for your prompt reply. I did find a link to above wiki page
in one of Oved's earlier post on this mailing list. I found the
documentation very helpful.
*
Hashtable env = new Hashtable();
env.put(java.naming.factory.initial,
com.sun.jndi.ldap.LdapCtxFactory);
env.put(java.naming.factory.url.pkgs, com.ibm.jndi);
env.put(java.naming.provider.url,
ldap://ldap-server:389);
String dn = null;
try{
InitialDirContext dirContext = new
InitialDirContext(env);
SearchControls constraints = new
SearchControls();
String[] attr = new String[] {uid};
constraints.setSearchScope(SearchControls.SUBTREE_SCOPE);
constraints.setReturningAttributes(attr);
NamingEnumeration ne =
dirContext.search(ou=ldpap-server-name,o=ibm.com,
(mail= + intranetID + ),
constraints);
**
But when I try to use
org.ovirt.engine.core.utils.ipa.SimpleAuthenticationCheck.java, I get a
javax.naming.AuthenticationException: [LDAP: error code 49 - Invalid
Credentials]
I am issuing - ldapTemplate.search(, , contextMapper);
Where contextMapper is RHDSUserContextMapper and
screenshots of ldapTemplate are attached.
As you willl probably see in Oved's WIKI, you don't need to provide
RHDSUserContextMapper - the name may be misleading, but this class is
for RedHat DS directory service - I think you need to have context
mappers for IBM Tivoli DS.
In addition you will have to add your own provider type, as can be seen
for example in GetRootDSE java (we send a ROOT DSE query in order to
understand what is our provider type, as currently engine-core
supports more than one type of DS.
Yes, I understand that there will be much more code changes to add
support for a new LDAP server. But my this post was to find the reason
for AuthenticationException.
There may be issues with the way I have setup filter and baseDN; but
that should not give AuthEx. At this time I am looking for ways to get
rid of authentication exception. Also, when using simple authentication,
why do I need to give password? I can run ldapsearch -LLL
(mail=intranetID) -h ldap-server:389 -x without password to give
me expected results.
This is a good question - I admit I did not work thoroughly enough with
SIMPLE authentication - maybe we can bypass this.
I looked at the code of this class - it uses Spring-LDAP
LdapContextSource class which extends AbstractContextSource which uses
SimpleDirContextAuthenticationStrategy as the default authentication
strategy - so I guess that playing with the code of this example, and
ignoring the password may work for you.
Thanks for the hint. While playing with AbstractContextSource class, I
was able to find the property AnonymousReadOnly. Setting it to 'true'
eliminated the AuthEx.
Regards,
Sharad Mishra
IBM
I would like to also point out that when I look at Spring-LDAP's
SimpleDirContextAuthenticationStrategy I it does set
env.put(Context.SECURITY_CREDENTIALS, password) (look at public void
setupEnvironment method ) - so what I have in mind is that you might
need to create your own AuthenticationStrategy - see for example
org.ovirt.engine.core.bll.adbroker.GSSAPIDirContextAuthenticationStrategy -
an authentication strategy that Oved, Roy and myself worked on to
support kerberos/GSS-API authentication with Spring-LDAP.
You will have to call after you implement such strategy a call to
context.setAuthenticationStategy with your implemented
AuthenticationStategy (for example, I think it can be placed after the
line of - LdapContextSource context = new LdapContextSource(); at
SimpleAuthenticationCheck.java
I think I gave you some pointers here,
Feel free to ask more questions
Yair

First, of all, I didn't manually do any mounting or other manipulations on the node, or the ovirt-engine machine, I believe. I followed the documentation in the oVirt 3.0 Installation Guide. Second, I just noticed that the virtual disk was created in the export domain, and not the data domain. I don't think that's as it should be. I created it through the oVirt admin portal, though, and I didn't see any options during the VM creation about placement of the disk. Okay, how is it mounted? Here are the mount options of all three domains exported from the ovirt-engine machine: mount|grep domain oravm3.acbl.net:/datadomain/ on /rhev/data-center/mnt/oravm3.acbl.net:_datadomain type nfs4 (rw,relatime,vers=4,rsize=524288,wsize=524288,namlen=255,soft,nosharecache,proto=tcp,port=0,timeo=600,retrans=6,sec=sys,clientaddr=172.16.2.52,minorversion=0,local_lock=none,addr=192.168.118.10) oravm3.acbl.net:/exportdomain/ on /rhev/data-center/mnt/oravm3.acbl.net:_exportdomain type nfs4 (rw,relatime,vers=4,rsize=524288,wsize=524288,namlen=255,soft,nosharecache,proto=tcp,port=0,timeo=600,retrans=6,sec=sys,clientaddr=172.16.2.52,minorversion=0,local_lock=none,addr=192.168.118.10) oravm3.acbl.net:/isodomain/ on /rhev/data-center/mnt/oravm3.acbl.net:_isodomain type nfs4 (rw,relatime,vers=4,rsize=524288,wsize=524288,namlen=255,soft,nosharecache,proto=tcp,port=0,timeo=600,retrans=6,sec=sys,clientaddr=172.16.2.52,minorversion=0,local_lock=none,addr=192.168.118.10) I do notice that they all say nfs4, and I've seen some postings about dont' use nfs4.
