Hello,
How to optimal configure 4 node cluster for any one node goes to
maintenance without stopping VM ??
a) replica 4 - but it takes a lot of space
b) disperse 3+1 ( raid 5 ) - but bad performance and not visible by
oVirt 3.7.2
c) stripe2+replica2 = but VM paused
any other idea ?

SPICE Through a Router? Squid?
by alexmcwhirter@triadic.us
I have a dual host setup working right now. Host 1 runs the engine and
is also a node. Host 2 does DB storage and NFS storage. The WebSockets
proxy is running on Host1.
My question is how do I run this behind a router? I am correct in
understanding that the WebSockets proxy acts as the spice access point
for all of the nodes in the cluster / datacetner? or does each node host
need a direct connection for spice?
the .vv file I receive from the management console specifies the
engine's private IP address which works fine when inside the ovirt
management LAN, but it wont route from WAN obviously.
So essentially i guess i need squid to rewrite the served vv file to the
public IP and somehow make the ports work correctly, which is difficult
considering every time a VM is created it also adds its own spice port,
correct?

connecting my oVirt engine to a 100mb switch
by Andrew Precht
Hi all,
I’m having problems connecting my oVirt engine to a 100mb switch. I’m not
having any problems connecting to 1gb. But, I need to also have a
connection to a 100mb network.
I’ve tried configuring ethtool_opts on the interface. However, this only
results in the NIC not coming up and showing: Speed: Unknown! and Duplex:
Unknown! (255), when I run ethtool ethX
Is it possible to connect the engine to a 100mb switch?
Thanks
PS. I also posted this question over on the oVirt G+ page. I apologize if
that's incorrect but I have G+ open all day...

VSDM on Engine
by Matt .
Hi Guys,
I wonder if some people have installed VDSM on the engine after the
engine was installed.
As this is supported on the All-In-One solution I wonder if it's also
supported now on a manual install.
Cheers,
Matt

Upgrade path
by Johan Kooijman
Hi all,
What would be the best upgrade path for upgrading a 3.5.2 cluster from C6
to C7?
Am I right in understanding that a cluster can have mixed hosts, but once a
VM is on a C7 host, it cannot be migrated back to C6?

engine-reports portal and cpu cores
by Alexandr Krivulya
Hello,
why we have in reports host cores but not logical cpu cores? For example
in "Cluster Capacity Vs. Usage" report I always have more vCores then
Host Cores.
Thank you.
