Export VM from oVirt/RHEV to VMWare
by Colin Coe
Hi all
We run RHEV exclusively and I need to export a guest to one of our vendors
for analysis.
The vendor uses VMWare. How can I export a VM in OVF format out of RHEV
v3.5.8?
Thanks

Error creating a storage pool
by Sergei Hanus
Hi, All!
When trying to attach iscsi device from my storage system, ovirt complains,
that it cannot create a storage pool.
In logs I can see only this:
----------------------------------------------------------
RuntimeError(u'Error creating a storage pool:
(u"spUUID=3fcace71-cd2b-4ab4-9d64-8ef926ead05a,
poolName=hosted_datacenter, masterDom=71b0d510-c24a-49fa-86ec-6b5ebf530140,
domList=[u\'71b0d510-c24a-49fa-86ec-6b5ebf530140\',
u\'793985b7-9d11-44a4-bf68-4b509a967a52\'], masterVersion=1, clusterlock
params: ({\'LEASETIMESEC\': 60, \'LOCKPOLICY\': \'ON\', \'IOOPTIMEOUTSEC\':
10, \'LEASERETRIES\': 3, \'LOCKRENEWALINTERVALSEC\': 5})",)',), <traceback
object at 0x35935a8>)
-----------------------------------------------------------
I have verified, that this block device can be successfully connected and
partitioned on the same server using standard tools (iscsiadm, parted,
mount), so, storage system on its own is working fine.
My question is: what are requirements for block device in order for it to
be compliant with ovirt? I know, that block size must be 512 bytes, but
anything else?
Thank you in advance, any comments appreciated.
Sergei.

Hi,
Someone can tell me what kind of informations I can get from ovirt
reports? oVirt web page is poor about it.
Screenshots will be helpful.
Thank you,

Upgrade cluster + adding nodes
by Davide Ferrari
Hello everyone
currently I've a 4-nodes oVirt 4.0.4 cluster running on CentOS 7.2.
Given that we have now oVirt 4.0.6 and CentOS 7.3, what's the best update
path? I was reading threads about qemu-kvm-ev 2.6 when CentOS 7.3 was
released but I was wondering if with 4.0.6 release something has changed.
Moreover, I'd like to add 4 more nodes in the near future, I guess I should
have all the same version and thus I must fully upgrade the original 4
nodes (both OS + oVirt) before adding new, fully up-to-date nodes, right?
Thanks!

oVirt Engine 4.0.5 and CentOS 7.3 Instability
by Rogério Ceni Coelho
Hi oVirt Gurus,
Happy new year to everyone !!!
I update oVirt Engine to 4.0.5 from 4.0.4 and Centos to 7.3 from 7.2 last
week and after that I have instability four times. Every time ovirt engine
seems to loose communication with one or more node servers like this image
below. Every time I rebooted oVirt engine server and everything came back
to normal.
Anyone with this kind of problem ???
