[Users] New user to oVirt, and I haz a sad so far...

[Will Dennis (Live.com)]

Thanks, Joop, for the node platform best practices. I did turn selinux from
"enforcing" to "permissive", and then when I tried to ping the engine by
fqdn, I saw that DNS lookups were failing (even tho resolv.conf looked
correct.) Did a 'yum remove NetworkManager" and then fixed the
/etc/sysconfig/network-scripts/ifcfg-<nic>, and then after a reboot, I can
now see the info for the node in the WUI on the manager, although the status
for the node is still "Non Operational". 

 

Where can I find the node install log (on the engine or the node, and name?)
(Sorry for noob status, but I am a quick learner ;)

 

Thanks,

Will

I mean exactly same issuse you had on Centos, I had on Fedora 19.

Did you disable selinux on nodes? 'cause that's what is causing SSh
connection closing

My setup:

1 engine on vmware  - fedora 19, up-to-date

 

 

2 nodes on IBM x series 3650  - fedora 19 based -oVirt Node - 3.0.3 -
1.1.fc19 with nodes beig in glusterfs cluster also.....



Right now, I'm banging my head against "Operation Add-Disk failed to
complete." , message I have got after adding a new virtual machine and try
to addd its disk

Hi all, ready for a story? (well, more of a rant, but hopefully it will be a
good UX tale, and may even be entertaining.)

Had one of the groups come to me at work this week and request a OpenStack
setup. When I sat down and discussed their needs, it turns out that they
really only need a multi-hypervisor setup where they can spin up VMs for
their research projects. The VMs should be fairly long-lived, and will have
persistent storage. Their other request is that the storage should be local
on the hypervisor nodes (they plan to use Intel servers with 8-10 2TB drives
for VM storage on each node.) They desire this in order to keep the VM I/O
local - they do not have a SAN of any sort anyhow, and they do not care
about live migration, etc

@Will
If the installation ends, either with or without error, it will give you a
log location. Upload the log to a paste.bin and mail the link.

@Gabi,
There should be more info in either the vdsm.log on the SPM server or in the
engine.log on the engine server, see above for lettings us know what the
error is.

Having installed oVirt, probably dozens of times, I have some guidelines:
- temporarily disable firewalld/iptables (if all works, enable should still
work, scripts with rules are generated and location is given)
- make selinux permissive either via setenforce 0 (until next boot) or via
/etc/selinux/config ( survives reboots), dont disable it!
- make sure fqdn work in both directions between engine and host(s) (either
using /etc/hosts or DNS)
- make sure NetworkManager is disabled and network enabled

Joop
