What recovers a VM from pause?
by Nicolas Ecarnot
Hello,
We're planning a move from our old building towards a new one a few
meters away.
In a similar way of Martijn
(https://www.mail-archive.com/users@ovirt.org/msg33182.html), I have
maintenance planed on our storage side.
Say an oVirt DC is using a SAN's LUN via iSCSI (Equallogic).
This SAN allows me to setup block replication between two SANs, seen by
oVirt as one (Dell is naming it SyncRep).
Then switch all the iSCSI accesses to the replicated LUN.
When doing this, the iSCSI stack of each oVirt host notices the
de-connection, tries to reconnect, and succeeds.
Amongst our hosts, this happens between 4 and 15 seconds.
When this happens fast enough, oVirt engine and the VMs don't even
notice, and they keep running happily.
When this takes more than 4 seconds, there are 2 cases :
1 - The hosts and/or oVirt and/or the SPM (I actually don't know)
notices that there is a storage failure, and pauses the VMs.
When the iSCSI stack reconnects, the VMs are automatically recovered
from pause, and this all takes less than 30 seconds. That is very
acceptable for us, as this action is extremely rare.
2 - Same storage failure, VMs paused, and some VMs stay in pause mode
forever.
Manual "run" action is mandatory.
When done, everything recovers correctly.
This is also quite acceptable, but here come my questions :
My questions : (!)
- *WHAT* process or piece of code or what oVirt parts is responsible for
deciding when to UN-pause a VM, and at what conditions?
That would help me to understand why some cases are working even more
smoothly than others.
- Are there related timeouts I could play with in engine-config options?
- [a bit off-topic] Is it safe to increase some iSCSI timeouts of
buffer-sizes in the hope this kind of disconnection would get un-noticed?

Can't perform search after setting up an Active Directory
by Alexis HAUSER
Hi,
I added an Active Directory server to RHEV, but I can't perform any search and I don't see any namespace in the interface.
I'm able to perform search using with the same search user DN / passwd and certificate :
LDAPTLS_CACERT=/somewhere/myca.pem ldapsearch -H ldaps://myserver.com -x -D 'CN=Something,DC=myserver,DC=come' -w 'mypaswd' -b 'CN=users,DC=something,DC=com'
in the engine.log, if I grep warn, I can see the following messages :
2016-05-25 05:54:55,840 WARN [org.ovirt.engine.core.bll.SearchQuery] (ajp-/127.0.0.1:8702-3) [] Illegal search: ADUSER@AD-authz:undefined: allnames=*: null

I also tried adding the following configuration but it didn't solve my problem :
sequence-init.init.100-my-basedn-init-vars = my-basedn-init-vars
sequence.my-basedn-init-vars.010.description = set baseDN
sequence.my-basedn-init-vars.010.type = var-set
sequence.my-basedn-init-vars.010.var-set.variable = simple_baseDN
sequence.my-basedn-init-vars.010.var-set.value = CN=Users,DC=something,DC=com
Any ideas ?
By the way, if I didn't rename my .profile and auth* files from my LDAP configuration, I had the LDAP namespace suggested by the web interface in my AD domain when trying to perform a search. Is that a bug ?

VMs using hugepages

Hello,
I try to get VM's to use hugepages by default. We use them on our manual
VM's set up for libvirt and experience performance advantages. I
installed vdsm-hook-hugepages, but according to
http://www.ovirt.org/develop/developer-guide/vdsm/hook/hugepages/ I have
to set hugepages=SIZE. Engine Web-Fronted doesn't show an option
anywhere to specify this.
I want the VMs to have:

Any hint ?

Clone, template, pools : how does it uses disk space ?
by Alexis HAUSER
Hi,
I would like to know what happens to storage when using the different method of cloning or generating VMs using templates / pools.
I'd like to know also in what case VM and virtual disks are totally independent and in what case they are not.
Sadly the RHEV documentation doesn't really provide these informations and I don't find any explicit informations about it.
For example, when making a VM from template, using pre-allocated disk option, for a 50GB Virtual disk, it only uses 3GB on the physical disk.
Another example, when making a pool of 10 VMs, based on a VM with a 50 GB virtual disk, only 2GB more space is used on the physical disk.
What is exactly done when this happens ?
Here are the case I would like to have informations about (physical storage, and independence of VMs) :
- using simple "clone function"
- making VM from template with "clone" mode
- making VM from template with "thin" mode
- making VM in pools
Is there modes calculating only the difference from the original VM, and other modes copying totally the informations from the virtual disk from the original VM ?

It seems I get the same problem with 4.0 beta too...
At least basic sh engine install should work in a beta, I think....

Any way to understand why the "create_connect" fails and why it decodes it
as "Network unreachable"?
BTW: during setup I see this message
[WARNING] Cannot locate gluster packages, Hyper Converged setup support
will be disabled.
Does it mean hyper converged setup could be supported in 4.0?
Thanks,

Ovirt 3.6.6 on Centos 7.2 not using native gluster (gfapi)
by Ralf Schenk
This is a multi-part message in MIME format.

Hello,
I set up 8 Hosts and self-hosted-engine running HA on 3 of them from
gluster replica 3 Volume. HA is working, I can set one host of the 3
configured for hosted-engine to maintenance and engine migrates to other
host. I did the hosted-engine --deploy with type gluster and my gluster
hosted storage is accessed as glusterfs.mydomain.de:/engine
I set up another gluster volume (distributed replicated 4x2=8) as Data
storage for my virtual machines which is accessible as
glusterfs.mydomain.de:/gv0. ISO and Export Volume are defined from NFS
Server.
When I set up a VM on the gluster storage I expected it to run with
native gluster support. However if I dumpxml the libvirt machine
definition I've something like that in it's config:
[...]
<disk type='file' device='disk' snapshot='no'>
<driver name='qemu' type='raw' cache='none' error_policy='stop'
io='threads'/>
<source
file='/rhev/data-center/00000001-0001-0001-0001-0000000000b9/5d99af76-33b5-47d8-99da-1f32413c7bb0/images/011ab08e-71af-4d5b-a6a8-9b843a10329e/3f71d6c7-9b6d-4872-abc6-01a2b3329656'/>

<boot order='1'/>
<alias name='virtio-disk0'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x06'
function='0x0'/>
</disk>
I expected to have something like this:
<disk type='network' device='disk'>
<driver name='qemu' type='raw' cache='none' error_policy='stop'
io='threads'/>
<source protocol='gluster'
name='gv0/5d99af76-33b5-47d8-99da-1f32413c7bb0/images/011ab08e-71af-4d5b-a6a8-9b843a10329e/3f71d6c7-9b6d-4872-abc6-01a2b3329656'>
<host name='glusterfs.mydomain.de'/>
</source>
[...]
All hosts have vdsm-gluster gluster installed:
[root@microcloud21 libvirt]# yum list installed | grep vdsm-*
vdsm.noarch 4.17.28-0.el7.centos @ovirt-3.6
vdsm-cli.noarch 4.17.28-0.el7.centos @ovirt-3.6

vdsm-yajsonrpc.noarch 4.17.28-0.el7.centos @ovirt-3.6
How do I get my most wanted feature native gluster support running ?

Hi.
I'm trying to run a Ubuntu cloud image on oVirt 3.6. It works fine with=
the 14.04 image or Centos 7 image but I have trouble with the 16.04 im=
age : I have no network and cloud-init dont receive any data from oVirt=
. Also, the VM takes about 5 minutes to boot (then I cant login as clou=
d-init dont seem to work).
I've validated the 16.04 image : I can boot it fine on my workstation r=
unning kvm.
