3.6 : VLAN / non VLAN
by Alexis HAUSER
hi,
I'd like to know what happens when you create a new network, tagged with VLAN for example 25 and using em2 :
- the packets outgoing from em2.25 are tagged, right ?
- the packets outgoing from em2 are tagged or not ?
- the result is packets inside ovirt are tagged, but when you go out of it and reach something from em2, are the packets still tagged ?

erros after upgrade
by Fernando Fuentes
Team,
After upgrading to 4.0.2 I am starting to get the following errors:
Failed to check for available updates on host ogias with message
'Command returned failure code 1 during SSH session 'root@IP''.
Do I need to update each hosts manually?
Regards,

Ovirt-Engine HA
by Sandvik Agustin
Hi Ovirt Users,
Do you have any documentation, tutorial, howto or workaround to perform or
to have an ovirt-engine HA? Iv'e tried to google about this but I can't
find any.
let's say I want to have two engine, engine1 is currently managing two
hypervisor, then engin2 is my reserved engine, so I can still managed those
vm that are running inside of my hypervisor if ever engine1 fails.
TIA :)

HostedEngine NIC setup files
by Hanson
Hi Guys,
I have edited /etc/sysconfig/network-scripts/ifcfg-eth0 &1 for the
various subnets we needed.
Somewhere along the line, when the hosted-engine boots, eth1 comes up
but eth0 does not. If I login using the upped interface and do an ifup
eth0 it comes up.
it is set to ONBOOT=yes in the config.
I know with the nodes, that these files are overwritten on boot. Where
should I be editing for the hosted-engine?
Thanks,
Hanson

3.5 / 3.6 stuck
by Erik Brakke
Hello,
I changed my cluster and data center compatibility from 3.5 to 3.6 with a
3.5 host. D'oh!
Engine: 3.6 on FC22
Host: 3.5 on FC22 (local storage)
- Can I change the data center and cluster back to 3.5? How?
- I tried to upgrade host to 3.6 in the GUI. Maintenance->Reinstall did
not work, and Upgrade option is greyed out. Is there a way to upgrade host
to 3.6?
Thanks

Cannot start hosted engine after last 4.0.1 packages
by Matt .
Hello,
I'm having issues after the last 4.0.1 package just before 4.0.2 came
out. My engine was running great, hosts started the vm also and the
hosted-engine command was working fine.
Now I get rpcxml 3.6 deprecated warning which I never got before. See
the attachment for this output.
I have checked is IPv6 was disabled, but it isn't as that is what is
needed for this.
Any clue ?
Thanks!
Matt
