ovirt-engine-webadmin-portal-debuginfo
by Edward Clay
Hello, I've run into a situation where I'm getting an uncaught exception
error and it seems like the log entries are obfuscated and one needs to
install the ovirt-engine-weba-portal-debuginfo rpm to decipher whats really
going on. I've installed this package and restarted the ovirt-engine but
I'm still not getting useful info in the ui.log. Any ideas what how I can
resolve this?
# rpm -qa|grep ovirt.*debuginfo
ovirt-engine-userportal-debuginfo-4.0.5.5-1.el7.centos.noarch
ovirt-engine-webadmin-portal-debuginfo-4.0.5.5-1.el7.centos.noarch
This is an example of the log entry when attempting to create a vm using a
template that contains a disk.

planned mailman restart
by Evgheni Dereveanchin
Hi everyone,
In a couple of minutes I will reboot the server
hosting all of our mailing lists (including this one)
to install software updates. It should come up quickly,
but if you have any problems sending to oVirt lists
please try again after a few minutes.
I will announce you as soon as the reboot is complete.
Regards,
Evgheni Dereveanchin

Restoring Hosted-Engine from a stale backup
by Doug Ingham
Hi all,
One of our engines has had a DB failure* & it seems there was an unnoticed
problem in its backup routine, meaning the last backup I've got is a couple
of weeks old.
Luckily, VDSM has kept the underlying VMs running without any
interruptions, so my objective is to get the HE back online & get the hosts
& VMs back under its control with minimal downtime.
So, my questions are the following...
1. What problems can I expect to have with VMs added/modified since the
last backup?
2. As it's only the DB that's been affected, can I skip redeploying the
Engine & jump straight to restoring the DB & rerunning engine-setup?
3. The original docs I read didn't mention that it's best to leave a
host in maintenance mode before running the engine backup, so my plan is to
install a new temporary host on a separate server, re-add the old hosts &
then once everything's back up, remove the temporary host. Are there any
faults in this plan?
4. When it comes to deleting the old HE VM, the docs point to a
paywalled guide on redhat.com...?
CentOS 7
oVirt 4.0.4
Gluster 3.8
* Apparently a write somehow cleared fsync, despite not actually having
been written to disk?! No idea how that happened...
Many thanks,

[Call for feedback] did you install/update to 4.1.0?
by Sandro Bonazzola
Hi,
did you install/update to 4.1.0? Let us know your experience!
We end up knowing only when things doesn't work well, let us know it works
fine for you :-)
If you're not planning an update to 4.1.0 in the near future, let us know

Your current state is not fully clear. Can you please describe it in detail?
How many hosts do you have? What's the state of each in the engine?
Do you have VMs that are ok? And if so, is it important to not stop them?
In any case, if you have hosts that do not have VMs on them, and in whatever
state, it's probably simplest to move them to maintenance, remove from the
engine, reinstall the OS, then try to add them.
If you try to add a host and it fails, please check/attach engine.log and
host-deploy log.
If you fail to activate a host, please check/attach engine.log.
Best,

jumbo frames inside vm best practices?
by Gianluca Cecchi
Hello,
I'm testing an Oracle RAC with 2 Oracle Linux VMs inside a 4.0.6
environment.
They run on two different hosts
I would like to configure RAC intracluster communication with jumbo frames.
At VM level network adapter is eth1 (mapped to a vlan 95 at oVirt hosts
side)
At oVirt side I configured a vm enabled vlan with mtu=9000
I verified that at hosts side I have
vlan95: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 9000
ether 00:1c:c4:ab:be:ba txqueuelen 1000 (Ethernet)
RX packets 61706 bytes 3631426 (3.4 MiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 3 bytes 258 (258.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
And able to do a
ping -M do -s 8972 ip
from each host to the other one
In VMs I configure the same MTU=9000 in ifcfg-eth1
But actually inside VMs it works erratically: the same ping test is ok
between the VMs but Oracle checks sometimes work and sometimes give error
on communication.
At initial cluster config, the second node fails to start the cluster.
I tried 5-6 times and also tried then to set mtu=8000 inside the VMs,
supposing some sort of inner overhead to consider (such as 2 times 28
bytes) but nothing.
As soon as I set MTU=1500 at VM side, the cluster is able to form without
any problem.
I can survive without jumbo frames in this particular case, because this is
only a test, but the question remains about eventual best practices to put
in place if I want to use jumbo frames.
One thing I see is that at VM side I see many drops when interface mtu was
9000, such as
eth1 Link encap:Ethernet HWaddr 00:1A:4A:17:01:57
inet addr:192.168.10.32 Bcast:192.168.10.255 Mask:255.255.255.0

collisions:0 txqueuelen:1000
RX bytes:25726242 (24.5 MiB) TX bytes:33573207 (32.0 MiB)
at host side I see drops at bond0 level only:
