Hello,
pls, howto change oVirt timeouts for status :
1) node ( brick) is power down / up
2) volume status for node(brick) is up/down
They are too long ( I'm expecting a few sec. not a lot of minutes )
If it has some spacial reason, let me know about, pls.
regs.

Ovirt PXE boot wierdness
by Edson Manners
I'm running oVirt 3.5 newly installed with one test VM.
I have the engine running on separate HW with eth0 being the management
interface
I have 2 compute nodes with eth0 being the management interface and eth1
having a vlan trunk with all of the VM networks
If I install a guest from the CD image it all works fine and picks up an
IP from the DHCP server.
However if I switch the boot order to PXE first the gPXE DHCP request
times out. Using tcpdump I can see the DHCP discovery packets get as far
out as the physical trunk interfact eth1 (i.e. it gets past all of the
virtual interfaces) but any other machines in that same VLAN don't see
the DHCP request and neither does the DHCP server.
My network settings are:
Name: TestCluster
External Provider: NO
Network label: TC
Enable VLAN tagging: 306
VM network: YES
MTU: Default 1500
Under 'Setup Host Networks'
Boot Protocol: DHCP
Any ideas?

vdsm lvm filter
by Renout Gerrits
Hi All,
I've got a setup with with ovirt and an equallogic iscsi. Im using the dell
hit drivers. Install all good, after a reboot the storage won't come up.
>From the vdsm logs i can see the volume groups can't be found. in the lvm
vgs command the following filter is used: [ '\''r|.*|'\'' ] .
If I change the LVMCONF_TEMPLATE in /usr/share/vdsm/storage/lvm.py and add
the filter [ "a|^/dev/eql/ovirt.*|" ], the volume group is found and
storage will be attached.
How is the lvm filter constructed? And how can i make sure my volume groups
are found without editing /usr/share/vdsm/storage/lvm.py?

LDAP bind DN generation problem
by Mitja Mihelič
This is a multi-part message in MIME format.
--------------040506020505040804040504
Content-Type: text/plain; charset=utf-8; format=flowed
Content-Transfer-Encoding: 8bit
Hi!
We just upgaded oVirt from 3.4 to 3.5 and now users cannot select the
LDAP domain on the login screen. Only internal is available.
Our LDAP server is actually a 389DS instance and we are using for
authentication in oVirt without Kerberos. The existing setup has worked
since the days of 3.2.
When we try to validate the domain, we get
[root@brda ~]# engine-manage-domains validate
Error: Cannot authenticate user ovirt to domain guest.arnes.si, details:
[LDAP: error code 32 - No Such Object]; nested exception is
javax.naming.AuthenticationException: [LDAP: error code 32 - No Such Object]
Failure while testing domain guest.arnes.si. Details: Cannot
authenticate user to LDAP server.
The LDAP log reports
[18/Jun/2015:13:52:38 +0200] conn=3 op=0 BIND
dn="uid=ovirt,ou=Peopledc=guest,dc=arnes,dc=si" method=128 version=3
As you can see there is a comma missing before "dc=guest,dc=arnes,dc=si".
Before the upgrade the bind DN was generated properly as
[18/Jun/2015:12:42:45 +0200] conn=10219 op=0 BIND
dn="uid=ovirt,ou=People,dc=arnes,dc=si" method=128 version=3
This looks like a bug.
Is there a quick fix we can do to fix this typo?
We are also interested in knowing what is the correct way in 3.5 to add
a domain that uses an LDAP server for its authentication source without
Kerberos.
Kind regards, Mitja

<br>
This looks like a bug.<br>
Is there a quick fix we can do to fix this typo?<br>
<br>
We are also interested in knowing what is the correct way in 3.5
to add a domain that uses an LDAP server for its authentication
source without Kerberos.<br>
<br>
Kind regards, Mitja<br>

ovirt-shell : which default start mode?
by Nicolas Ecarnot
Hi,
Since long, I'm using some scripts to create VM, add some components and
start them. My script is booting them in PXE.
After an upgrade in 3.5.1, I'm witnessing that the default boot is now
primarily using hard disk, and not PXE.
Is there a way for the ovirt-shell to ask a boot via PXE?
In fact, I find that the embeded inline help of ovirt-shell is difficult
to read, and some *tree view* of all options would be much better readable.

My network iface:
#cat ifcfg-eno1
HWADDR="*;*;*;*;*;*"
DEVICE=eno1
BRIDGE=ovirtmgmt
ONBOOT=yes
IPV6INIT=no
MTU=1500
NM_CONTROLLED=no
#cat ifcfg-ovirtmgmt

BOOTPROTO=none

DEFROUTE=yes

BUT, my host writes the error and it is not added in Cluster!
How correctly to add a host, or to make network interfaces?
