ovirt 3.4 hosted-engine static IP
by Klas Mattsson
Hello, new user here!
I've noticed that the virtual interface ovirtmgmt gets an IP address by
DHCP.
Is there any good way to make it static instead?
I've seen a workaround which is basically:
run hosted-engine --deploy
Let it configure the management interface.
Cancel
Change the IP adress to static in:
/etc/sysconfig/network-scripts/ifcfg-ovirtmgmt
Run hosted-engine --deploy again.
Would this be the current appropriate solution?
Also, is it possible to change this later on, after the installation is
finished?
I would appreciate any assistance.
With my best regards

[Users] oVirt Node Bootloader issue
by Nauman Abbas
Hello there
I'm facing this problem and this has happened to me multiple times on
different machines. I have two hard drives in my system (lets say HDD A and
HDD B). I boot the system from the oVirt node CD to install it. Now I want
the bootloader and the node installation both to go on HDD B and not HDD A.
When I get to the screen which asks me to select the hard-drive for
bootloader I use the arrow keys to select HDD B and press Enter (have also
tried pressing space or just use tab and continue while it's selected).
Then I get to the screen asking where to install the node. I select HDD B
and unselect HDD A. I keep the partitioning setup as default ( have also
tried manual and kept 5GB unused on HDD A). When I get to install part. It
installs the node fine on HDD B as expected but it always gets the
boot-loader on HDD A. This issue has wasted many of my days on different
machines and I can't seem to find a way around.

Connection hickups with Pfsense and Carp
by Matt .
Hi Guys,
I'm facing some issues with Pfsense and a Carp setup where connections are
not dropped but the connection is not stable.
I have set macspoof on the vm that runs Pfsense, this because it needs it
for Carp.
My TCPdump actually give good results, a single P so that looks also well.
I have tested this with things like sending emails and so on, uploading
large files. It seems on sending emails that you most of the time have to
canceld a send and resend it, sending goes well than. A tcpdump on such
mailserver looks well.
For uploading large images it seems that it's slow in uploading because of
disconnects, also a good tcdump.
Do I need to make specific settings on the vswitch or the real switch
between ?
Or is something else going on ?
Cheers,
Matt

[Users] Post-Install Engine VM Changes Feasible?
by Joshua Dotson
Hi,
I'm in the process of installing 3.4 RC(2?) on Fedora 19. I'm using hosted
engine, introspective GlusterFS+keepalived+NFS ala [1], across six nodes.
I have a layered networking topology ((V)LANs for public, internal,
storage, compute and ipmi). I am comfortable doing the bridging for each
interface myself via /etc/sysconfig/network-scripts/ifcfg-*.
Here's my desired topology:
http://www.asciiflow.com/#Draw6325992559863447154
Here's my keepalived setup:
https://gist.github.com/josh-at-knoesis/98618a16418101225726
I'm writing a lot of documentation of the many steps I'm taking. I hope to
eventually release a distributed introspective all-in-one (including
distributed storage) guide.
Looking at vm.conf.in, it looks like I'd by default end up with one
interface on my engine, probably on my internal VLAN, as that's where I'd
like the control traffic to flow. I definitely could do NAT, but I'd be
most happy to see the engine have a presence on all of the LANs, if for no
other reason than because I want to send backups directly over the storage
VLAN.
I'll cut to it: I believe I could successfully alter the vdsm template (
vm.conf.in) to give me the extra interfaces I require. It hit me, however,
that I could just take the defaults for the initial install. Later, I
think I'll be able to come back with virsh and make my changes to the
gracefully disabled VM. Is this true?

NFS service not starting after reboot

Need some quick help on this. I restarted one of my oVirt nodes and it
