ovirt 3.4 hosted-engine static IP
by Klas Mattsson 19 May '14

19 May '14

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 Klas Mattsson

[Users] oVirt Node Bootloader issue
by Nauman Abbas 16 May '14

16 May '14

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.

[Users] Cannot Ping CARP/Spoofed address
by Matt . 15 May '14

15 May '14

Hi Guys, I'm trying to use Mac spoofing for a Carp setup which is not working out well. Following here: https://forum.pfsense.org/index.php?topic=68137.0 and here http://lists.ovirt.org/pipermail/users/2013-October/017217.html This should be working by: engine-config -s EnableMACAntiSpoofingFilterRules=false --cver=3.3 (The clusters are 3.3 compatible) In some strange way this is not working in any way. How can we solve this, as I'm out of options. Thanks! Matt

Connection hickups with Pfsense and Carp
by Matt . 15 May '14

15 May '14

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 14 May '14

14 May '14

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?

Is it it me or does it take a very long time to delete a snapshot? Upwards of 30 minutes to delete a snapshot of a 7 GB drive

Hello all Need some quick help on this. I restarted one of my oVirt nodes and it doesn't seem to go up after that. I have done some troubleshooting and found out that the nfs-server service is not going up. Here's the error. [root@ovirtnode2 /]# systemctl start nfs-server.service Job for nfs-server.service failed. See 'systemctl status nfs-server.service' and 'journalctl -xn' for details. [root@ovirtnode2 /]# systemctl status nfs-server.service nfs-server.service - NFS Server Loaded: loaded (/usr/lib/systemd/system/nfs-server.service; disabled) Active: failed (Result: exit-code) since Mon 2014-04-14 06:43:15 UTC; 18s ago Process: 2751 ExecStart=/usr/sbin/rpc.nfsd $RPCNFSDARGS $RPCNFSDCOUNT (code=exited, status=203/EXEC) Process: 2749 ExecStartPre=/usr/sbin/exportfs -r (code=exited, status=0/SUCCESS) Process: 2747 ExecStartPre=/usr/libexec/nfs-utils/scripts/nfs-server.preconfig (code=exited, status=0/SUCCESS) Apr 14 06:43:15 ovirtnode2 exportfs[2749]: exportfs: can't open /var/lib/nfs/rmtab for reading Apr 14 06:43:15 ovirtnode2 systemd[2751]: Failed at step EXEC spawning /usr/sbin/rpc.nfsd: No such file or directory Apr 14 06:43:15 ovirtnode2 systemd[1]: nfs-server.service: main process exited, code=exited, status=203/EXEC Apr 14 06:43:15 ovirtnode2 systemd[1]: Failed to start NFS Server.
