Thanks!
No big deal as it's now working.

Hi
I am unable to migrate to hypervisor that's sandy bridge CPU.
The cluster supports CPUs that old.

Upgrading librbd1 and librados2 for oVirt 4.2.x
by andreas.elvers+ovirtforum＠solutions.work
Hallo Group !
I am in need of upgrading librbd1 and librados2 for a oVirt 4.2.x cluster.
The cluster was installed via node ng.
Taking the repository for Ceph Mimic or Luminous will end in a dependency
problem because liburcu-cds.so.1 is already installed as a more recent version
provided by the oVirt repository.
A hint on how to get a more recent versions of the above libraries would be very
much appreciated.
Thanks,
- Andreas

HA VMs not starting automatically on another host after host crash.
by Eduardo Mayoral
Hi,
Recently I have had 2 oVirt hosts (oVirt 4.2, CentOS 7.5) crash
unexpectedly (not at the same time). Both seem hardware related.
In both cases oVirt did detect the host as non responsive, did a
fence on the hosts and set the VMs which were running on the host at the
time as "Down". So far, so good.
The hosts were on 2 different clusters. Both had Migration policy /
resilience policy set to "migrate Virtual Machines". The VMs are not
configured as "Highly available", but my understanding is that with that
resiliency policy, this makes no difference. My (probably wrong)
expectation, is that oVirt should have attempted to start the VMs in
another host. It did not. A colleague started the VMs manually and they
started with no further issues.
So. How should I configure oVirt to try to start the VMs on another
host when the physical host they are running in crashes?
Thanks in advance!

VM has been paused due to unknown storage error. - Only on NFS / EMC
by jeanbaptiste＠nfrance.com
Hello,
I'm facing a strange issue on my OVirt Dev pool.
Indeed, when I create high disk load a VM (kickstart installation or iozone test for example) , VM is paused due to storage I/O error.
Problem is 100% reproducible, and is located only on NFS (v3 and v4) on my EMC VNXe3200 NAS's (I have a 10TB and a 20TB NAS)
I have done test (simple iozone -a) with VM 1 vCPU / 2GB RAM and 2 disk (1*20GB + 1*10GB). Both VMs disk are placed into the same SAN / NAS for each test. Results are:
- EMC VNXe3200 (10TB) NFSv3 => VM stopped after 10- 30s iozone lauch
- EMC VNXe3200 (20TB) NFSv3 => VM stopped after 10- 30s iozone lauch
- EMC VNXe3200 (10TB) ISCSI => No problem, iozone test finish, and performance are "standard" regarding load of the VNXe (60MB/s sequential Write for info)
- EMC VNXe3200 (20TB) ISCSI=> No problem, iozone test finish, and performance are "standard"regarding load of the VNXe (40-60MB/S sequential Write for info)
- NETAPP FAS2240 NFSv3 => No problem, iozone test finish, and performance are good (100MB/s sequential Write for info)
- Freebsd10 NAS NFSv3 => No problem, iozone test finish, and performance are good regarding NAS conf (80MB/s sequential Write for info)
I can't explain why I have an issue on NFS and I have not issue on ISCSI (on the same EMC VNxe3200...).
NFS default params are keeped when storage added to datacenter:(rw,relatime,vers=4.0,rsize=131072,wsize=131072,namlen=255,soft,nosharecache,proto=tcp,port=0,timeo=600,retrans=6,sec=sys,clientaddr=XXXXXXX,local_lock=none,addr=XXXXXX)
(rw,relatime,vers=3,rsize=131072,wsize=131072,namlen=255,soft,nolock,nosharecache,proto=tcp,timeo=600,retrans=6,sec=sys,mountaddr=XXXXXX,mountvers=3,mountport=1234,mountproto=udp,local_lock=all,addr=XXXXXX)
Debug logs on host does not help me a lot:

Update disk alias by using ovirtsdk4
by branimirp＠gmail.com
Hello list!
I have been trying to rename a disk alias that defaults to "some_template_name-Disk1" to something more logical by using ovirtsdk4 (in my example to "vm2_disk_0"). On the list itself, I saw a couple of examples for older version of SDK. Basically, I am trying to create a VM and then update its properties, notably "alias" attribute that can be found in types.Disk. The first portion of the code works well (vm provisioning), but second one (alias update) does not, causing the TypeError exception. Obviously, I am doing something wrong here. I have spent most of the time trying to figure out how to actually do this. I would kindly ask for some hint.
Thank you in advance!
Regards,
Branimir

Upgrading librbd1 and librados2 for oVirt 4.2.x
by Andreas Elvers
Hello,
I am in need of upgrading librbd1 and librados2 for a oVirt 4.2.x cluster.
The cluster was installed via node ng.
Taking the repository for Ceph Mimic or Luminous will end with a dependency
problem because liburcu-cds.so.1 is already installed as a more recent version.
A hint on how to get a more recent versions of the above libraries would be very
much appreciated.
Thanks,

Data Center non-responsive, storage not loading, and psql errors after importing an ova
by josh＠nightscapetech.com
I posted about this a few months ago on Reddit when it happened the first time, and I have now repeated it on two more separate installations. I have a simple oVirt 4.2 hosted-engine setup, two hosts, with a qnap NAS as the shared NFS storage. I copied an ova file (exported from vmware) to the NFS storage. I then imported it by logging into the engine gui, going to "Virtual machines", selecting the host/file path/datacenter/etc, and starting the import. Once I started the import, I get an alert that it failed almost immediately, followed by a notice that the data center is in a non-responsive state. Clicking on the "storage" tab under Data Center, or going to the "Storage Domain" page directly yields the three ". . ." loading animation, which never ends.
I can still see the storage mounts on the hosts, and I can move files to and from them.
the engine.log file on the hosted-engine VM contains a lot of the following lines:
Caused by: org.springframework.dao.DataIntegrityViolationException: PreparedStatementCallback; SQL [select * from getstorage_domains_list_by_imageid
(?)]; ERROR: integer out of range
Where: PL/pgSQL function getstorage_domains_list_by_imageid(uuid) line 3 at RETURN QUERY; nested exception is org.postgresql.util.PSQLException: ER
ROR: integer out of range
Where: PL/pgSQL function getstorage_domains_list_by_imageid(uuid) line 3 at RETURN QUERY
at org.springframework.jdbc.support.SQLStateSQLExceptionTranslator.doTranslate(SQLStateSQLExceptionTranslator.java:102) [spring-jdbc.jar:4.3.
9.RELEASE]
What I have tried:
Restarting the hosted-engine service
Restarting nfs and vdsm services
Rebooting the hosted-engine
Rebooting both hosts
Entering an exiting maintenance mode (one host never came out of maintenance, and refuses to with the error " General command validation failure ")
Any idea what might have happened? And what should I have done to try to rectify it? Entering maintenance mode and restarting services seems to have made things much worse.
