Running into an oddity when changing the name attribute of a VM. When
the name attribute is changed via the either the WebAdmin or PUP it does
not update the <Name> element within the VM OVF. The database table
entry: vm_static --> VM_name does however get updated.
Upon trying to start the VM or restart it in the case of updating the
name while it was in a running state the below will occur:
=20
VM <vmname> is down. Exit message operation failed: domain '<vmname>
'
already exists with uuid <UUID>.
VM <vmname> was started by <username> (Host: <ovirtnodehostname>).
=20
This can be worked around however by simply hand-editing the VM OVF and
changing the <Name> element to the desired name.
=20
This is observed with the current released version of the ovirt-engine
(ovirt-engine-3.0.0_0001-1.6)

Hi everyone,
One of the requirements behind the system that I am attempting to build is =
that there should be no local storage. I've noticed that I cannot add local=
storage hosts to the same datacenter and cluster. It seems awkward to have=
a 1:1:1 ratio of datacenter to cluster to host. Is there anything that I a=
m missing or is there a reason for why this is the design in ovirt?
I plan to use the system to provide a service where end-users will make API=
calls to create and delete VMs. It will be critical that oVirt-engine not =
be a single-point of failure. I can't seem to find much information about w=
hether oVirt-engine is designed with redundancy in mind. Is oVirt capable o=
f a failover or an active-active configuration?
Finally, I am attempting to automate registration of hosts to oVirt and am =
hitting this when I try to add a local storage domain:
[oVirt shell (connected)]# create storagedomain --host test1 --type "Data (=
Master)" --storage-type "Local on host"
unknown error: 'str' object has no attribute 'export'
Is this a bug with ovirt-shell that I should file or am I doing something w=
rong? The host is in maintenance mode, I do not see anything in the engine =
logs after I run the command.
Thanks,
Andrey

i didn't understand if you don't want to use local storage but trying to
use it?
I’ve noticed that I cannot add
local storage hosts to the same datacenter and cluster. It seems awkward

yes, you need a 1:1:1 for now. plan is to remove this need in the future
by allowing to associate a storage domain with a cluster or host
directly rather than only at DC level.
I plan to use the system to provide a service where end-users will make
API calls to create and delete VMs. It will be critical that
oVirt-engine not be a single-point of failure. I can’t seem to find much
information about whether oVirt-engine is designed with redundancy in
mind. Is oVirt capable of a failover or an active-active configuration?
if engine is down, VMs can still continue to run.
for making engine HA, best approach right now is to use clustering
technologies.
Finally, I am attempting to automate registration of hosts to oVirt and
am hitting this when I try to add a local storage domain:
I saw you solved this - but worth mentioning for ovirt-node, it has auto
registration to engine flow.
[oVirt shell (connected)]# create storagedomain --host test1 --type
"Data (Master)" --storage-type "Local on host"
unknown error: 'str' object has no attribute 'export'
Is this a bug with ovirt-shell that I should file or am I doing
something wrong? The host is in maintenance mode, I do not see anything
in the engine logs after I run the command.
Thanks,
Andrey

Sorry, that was a typo on my part. There should be no shared storage.

Thanks for the explanation.

I looked at auto-registration a little bit, but I realized that I would need to setup dcs
and clusters so I decided to do everything through the API via ovirt-shell.

Sorry, that was a typo on my part. There should be no shared storage.
just wondering - is the requirement for isolation or resources?
(if resources, have you looked at gluster?)

It is all about resources. We need VMs to have fast I/O without expensive SAN or NAS
solutions. I have looked a little bit at gluster and this certainly looks promising:
http://gluster.org/community/documentation/index.php?title=Red_Hat_Enterp...
. I'd have to test it out and see if it can provide the I/O performance we are looking
for.

Hi everyone,
I have one more question:
I want to use local storage, but I want to register the same template on each node. I am
working on a mechanism right now where I detach and remove the Export domain, add it for a
target dc/cluster/host, import the template, deactivate+detach+remove the export domain
and repeat for the next host. Is this mechanism the only choice I have? Is there a better
way?
Thanks,
Andrey

you need the template on each DC (until you would be able to mix types
of storage domains and use a shared NFS for the template for example).
this feature should allow you to import it more than once, but not
implemented yet:
http://www.ovirt.org/wiki/Features/ImportMoreThanOnce
that hints your current solution will not work, since you cannot import
the same object today more than once (even to another DC).
since this is local storage, you can hack it a bit and just create a
template with the disk on all DCs, then dd/rsync the real one to
override the created disk in all local storage.

Good to know the feature is in the pipeline :). I was able to work around it by writing a
script that does the
following:
a) copy origin OVF with dir structure in /master in the export domain
b) copy dir structure for associated image in /images
c) hard link origin image to the new image uuid dir
d) replace uuid in .meta file and uuids in new OVF
e) additionally, replace instanceId for VM network as well as storagePoolId (not sure if
storagePoolId replacement was
necessary
Thanks,
Andrey
