Re: [ovirt-users] Engine Down Score is 0

The hosted engine fails to start due to:
Traceback (most recent call last):
File "/usr/share/vdsm/virt/vm.py", line 714, in _startUnderlyingVm
self._run()

libvirtError: Cannot get interface MTU on 'None': No such device
The Hosted Engine VM has been configured with:

<mac address="00:1a:4a:16:01:75"/>
<model type="virtio"/>
<source bridge="storage"/>
<link state="up"/>
</interface>
Not sure how you got there.
Can you share steps you did before having this issue?

Importing VMs from kvm to oVirt. "VM zarafa is down with error. Exit message: Failed to find the libvirt domain."
by Marc Pfaendler
Hello
I'm trying to import an existing kvm VM into oVirt 4.1. It a new server
with a fresh installation of oVirt.
I'm working with the oVirt gui to achieve this.
After moving the VM from the old system into the export folder, the gui
allows me to import it.
The import seems to succeed. But after the VM is imported it fails to start.
Giving this error:
"VM zarafa is down with error. Exit message: Failed to find the
libvirt domain."
Cheers

Re: [ovirt-users] Ovirt Hosted-Engine VM iptables
by Andrew Dent
I can add a rule into ipdates such as this
iptables -I INPUT -s 192.168.0.10 -p tcp -m tcp --dport 5666 -j ACCEPT
I can see the addition has succeeded with this
iptables-save > /etc/sysconfig/iptables
But a reboot of the Engine VM (not the Host) doesn't keep the new rule,
and I was expecting that during bootup CentOS would read from
/etc/sysconfig/iptables.
Alas it isn't.
Found a solution.
After reading this
https://stackoverflow.com/questions/24756240/how-can-i-use-iptables-on-ce...
I installed iptables-services
But once installed I found that iptables -L showed no rules.
thankfully I still had the default hosted-engine rules in
/etc/sysconfig/iptables
iptables-restore < /etc/sysconfig/iptables
Then.....
service iptables save
restored the default hosted-engine rules including my rule for 5666.
Rebooting the hosted-engine VM and my rule 5666 for NRPE is still there.
Success!!
To answer your other questions
> Did you ask to configure the firewall during engine-setup?
Yes.
Looks like it setup firewalld for me.
> Alternatively, it's recommended to use firewalld.
For the moment I have disabled firewalld and are using iptables....Is
there a reason why firewalld is preferred over iptables?
Kind regards
Andrew
