Change local DC host address
by Alexandr Krivulya 18 Aug '16

18 Aug '16

Hi! There is any way to change host address in a local DC? In web-ui it's grayed out, ovirt-shell gives an error: status: 400 reason: Bad Request detail: Host Address can not be modified due to Security restrictions. In order to change Host Address, Host has to be reinstalled Reinstall host is not a solution with local DC.

Is hosted engine supported in hosts with diff CPU types?
by Fredy Sanchez 17 Aug '16

17 Aug '16

Hi all, I am deploying hosted engine in what will hopefully become our 4th oVirt cluster. The engine is up and running happily in host 1 already, but I am running into the following when running hosted-engine --deploy in hosts 2 and 3: The following CPU types are supported by this host: - model_Opteron_G3: AMD Opteron G3 - model_Opteron_G2: AMD Opteron G2 - model_Opteron_G1: AMD Opteron G1 [ ERROR ] Failed to execute stage 'Environment customization': Invalid CPU type specified: model_SandyBridge Host 1 has an Intel chip. Hosts 2 and 3 have an AMD chip. Is this a supported config? If so, how can I bypass the error? Thank you very much. Cheers, Fredy

Ovirt 4.0 Login Issue
by Melissa Mesler 17 Aug '16

17 Aug '16

I am running 4.0 on CentOS 7.2. Sometimes when I first log in to the admin page, it will give me and error that says "Request state does not match session state." Then if I go through the process of logging in again, it will go through with no issue. It doesn't do this every time but it does do it quite often. Any ideas on why? - MeLLy

Upgrade hosts/nodes from engine
by Hanson 17 Aug '16

17 Aug '16

Hi Guys, Quick question, I have my nodes on a bond-bridge-privateVlan setup, and my engine on a bond-bridge-publicVlan setup for remote monitoring. Understandably, the nodes are complaining that they are failing updates. (They're on a private vlan, and only configured with IP's in that vlan, the public vlan doesn't have IP's set on the hosts so they can pass it to VMs). Is there a way to have the engine do the updates on the node using its internet connection, like a proxy? For security reasons I like to have the nodes not publicly accessible, as we see hundreds if not thousands of ssh attempts, and root would probably be the most attacked account. Thanks, Hanson

Gluster replication on 1Gb interfaces
by Fernando Frediani 16 Aug '16

16 Aug '16

Hi all. I understand using 10Gb interfaces when using Gluster is advised for helping with data replication specially in situations where a node went down for a while and need to re-sync data. However can anyone tell if using one 1Gb interface dedicated for it in hosts with 1.8 TB of Raw storage would be still Ok or can it cause severe impact on performance ? What are the chances of a 1Gb nice being saturated during normal operation ? Thanks Fernando
