Mix local and shared storage on ovirt3.6 rc?
by Liam Curtis 26 Nov '15

26 Nov '15

Hello all, Loving ovirt...Have reinstalled many a time trying to understand and thought I had this working, though now that everything operating properly it seems this functionality is not possible. I am running hosted engine over glusterfs and would also like to use some of the other bricks I have set up on the gluster host, but when I try to create a new gluster cluster in data center, I get error message: Failed to connect host <myhost> to Storage Pool Default. I dont want to use just gluster shared storage. Any way to work around this?

Adding direct lun from API doesn't populate attributes like size, vendor, etc

VM Network activity on RHEV-M UI
by Marc Seward 26 Nov '15

26 Nov '15

I'm generating network activity on a RHEV 3.5 VM using iperf.The VM acts as an iperf client.On the client,iperf reports that data has been successfully sent to iperf server.The iperf server also shows that it's successfully receiving data from the iperf client.But,network is at 0% on the RHEV-M UI.The client and server are on different private networks. On the same VM,when I generate network activity by fetching a file from a public network using wget,the network column correctly shows activity on the RHEV-M UI for the VM. Could someone help me understand why I am unable to see network activity on the RHEV-M UI when iperf is used? Appreciate your help.TIA.

MacSpoof with multiple VM's -> bad/slow response on 3.5.3
by Matt . 09 Nov '15

09 Nov '15

Hi Guys, On a 3.5.3 updated cluster I see issues with macspoofed VM's. The cluster is a CcentOS 7 cluster which always performed well. I noticed that on my loadbalancers the macspoof true setting disspeared in the engine and when I added it and rebooted some other carp machines it was vanished at those machines. It's a quite simple setup: 2 static nodes in a mutiple hosts cluster with carp machines on it, per blade 1 Firewall, Pfsense, and one Loadbalancer ZEN. The cluster ID's differ on ZEN, and the carp IP's on pfsense have a different VHID's so I wondered if this is a known issue with the vanished macspoof true setting I found out (so the whole virtual IP doesn't work in that case). Some other cluster works fine without any issue, the spoofed systems here are on CentOS 6 This setup has run for more than a year without any issues. I hope someone has some information if this issue is known. Thanks Matt (sorry for my bad typing it's kinda early/late ;))
