[Users] Migrate Ovirt VMs to KVM(Fedora with virt-manager)
Hi I want to migrate an VM from Ovirt engine to KVM. for example to Fedora 17 and managed it with virt-manager. I know about migrate from KVM to Ovirt but how is vice versa? what steps required for it? Thanks. ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Hello, I just rebooted my iscsi SAN and the ovirt node 2.5.5fc17 did not enjoy that one bit. Does ovirt node support multi path i/o? Any information about this would be greatly appreciated.

[Users] Auto-start vms on boot?
It would seem that oVirt does not provide an standard way of forcing boot of virtual machines at boot. Pools can have pre-started vms as stated here: https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Enterprise_Virtualization/3.1/html/Administration_Guide/Prestarting_Virtual_Machines_in_a_Pool.html but pools imply state-less virtual machines and I am talking more about normal virtual machines. I've found this script: https://github.com/iranzo/rhevm-utils/blob/master/rhev-vm-start.py which could do to the trick if run at host boot. I've also thought (but not tried) to mark a virtual machine as Highly Available even if I have only one host (I mean, usually HA only makes sense when you have two hosts). Marking a VM as H.A. would do the trick? Any special reason why there isn't and standard way of marking which vms should be auto-started at boot? Just wanted to hear your thoughts before filling an RFE. Thank you. -- -- Adrián Gibanel I.T.

Re: [Users] Manage users without Red Hat Directory Server or IBM Tivoli Directory Server?
Supporting non-Kerberos LDAP with simple authentication and no DNS
integration would significantly decrease the work required for people
like Dennis. Instead of having to set up Kerberos and DNS and an LDAP
provider that integrates with both, he could just set up a very simple
LDAP server and use a physically secured network or SSL with
self-signed keys to protect his authentication traffic.
There are already LDAP servers that use simple backends, including an
OpenLDAP variant that uses /etc/passwd and /etc/shadow instead of a
db. If the requirement for Kerberos and DNS directory integration
were removed, and simple authentication worked, you would be able to
support pretty much anything out there in the linux/unix world.
That way oVirt wouldn't have to reinvent any wheels, and people like
Dennis would have significantly less costly and time-consuming
rebuilding of their networks to do before being able to implement
oVirt.

Dear Itamar,
we (German Air Navigation Services) would like to use oVirt for
testing our air traffic applications.
In our air traffic application system, there is no directory service,
since we don't need one. Consequently our test system has no
directory service too.
We differentiate only between root-users (manage the OS), air traffic
application operational-users and air traffic application
technical-users.
For three kinds of users a directory service would mean too much
overhead.
oVirt is complex enough, therefore it would be advantegous to have a
simple user-management without the need to install/configure/run a
directory service infrastructure.
Best regards
Dennis
Hi Dennis,
From what you're describing - you have to populate oVirt somehow with
3 groups -
root-users, air trafdfic application operational-users and air traffic
application technical-users.
Not sure if you have technical developers at your organization, but at
past we developed an internal broker [1] which is not
Ldap/Directory-Service based.
We have future thoughts about supporting not just directory services.
But for now - perhaps the quickest thing for you guys (if you have a
technical team of developers) is to write your own broker, similar to
the internal broker).
I actually saw a non ldap broker that was implemented based on the way
the internal broker was implemented.
But I really think you should reconsider your decision NOT to use ldap
directory-service
[1] - Internal broker - the piece of code responsible for the
admin@interal user
Yair
I feel that we do need a plain and simple user management broker (could
be file based similar to jboss user/group properties). Dennis concerns
about the time/money to invest in an up running
installation with few groups seems just.
we can make /etc/ovirt-engine/user-management/users.properties and
group.properties
users.properties:
#key could be considered as the DN
user1.name=Dennis
user1.id={UUID}
user1.groupids={admins group id},{others}
user1.pass=plaintext
group properties:
admins.id={UUID}
admins.desc=some description
there are enough implementations for these things, we don't need to invent
our own.

Dear oVirt-Community,
how can I add a new User? If I click “Add” under the “Users”-Tag of
the
web interface, I cannot create a new user. If I start a search,
only the
user “admin” is displayed.
Is it maybe not possible to create users out of oVirt?
Even users which I added locally (on the fedora host which runs the
ovirt engine) are not displayed.
Can you only manage users if oVirt is connected to a Red Hat
Directory
Server or IBM Tivoli Directory Server?
can you please explain the use case where there is no existing
directory
to handle group membership and authentication?
thanks,
