[HA] Restart guest on other node on network SAN problem
by Lionel Caignec 14 Sep '15

14 Sep '15

Hi, i've ovirt nodes connected to a data network (provide disk for guest) with 10Gb networking. Recently i face a problem : one of my node have lost connectivity to the SAN. So ovirt put all guest in "Pause" state, but when connectivity came back ovirt did not restart the Guest. So my question : is it possible on "disk connectivity lost" on one node, to restart guest on other node (HA features). Or at least auto resume guest when "disk connectivity" came back.

lc_messages issue in 3.6 beta 5 upgrade
by Jon Archer 13 Sep '15

13 Sep '15

Hi all, just wanted to share an error i'm seeing with the upgrade process from 3.5 to 3.6 b5. when running engine-setup on the hosted-engine I'm seeing an error saying that lc_messages should be en_US.utf8. problem is that isn't my locale, nor would it be the case in quite a lot of other installations. My lc_messages is set to en_GB.utf8 Install log shows the following 2015-09-14 00:05:29 DEBUG otopi.ovirt_engine_setup.engine_common.database database.execute:221 Result: [{'lc_messages': 'en_GB.UTF-8'}] 2015-09-14 00:05:29 DEBUG otopi.ovirt_engine_setup.engine_common.database database._checkDbConf:914 Mismatch: key='lc_messages', current='en_GB.UTF-8', expected=''en_US.UTF-8'' 2015-09-14 00:05:29 DEBUG otopi.context context._executeMethod:152 method exception Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/otopi/context.py", line 142, in _executeMethod method['method']() File "/usr/share/ovirt-engine/setup/bin/../plugins/ovirt-engine-setup/ovirt-engine/db/connection.py", line 115, in _customization show_create_msg=True, File "/usr/share/ovirt-engine/setup/ovirt_engine_setup/engine_common/database.py", line 1174, in getCredentials self._checkDbConf(environment=dbenv, name=name) File "/usr/share/ovirt-engine/setup/ovirt_engine_setup/engine_common/database.py", line 922, in _checkDbConf name=name RuntimeError: Engine requires lc_messages to be 'en_US.UTF-8'.

Problem with network VM
by Rocha Neto 13 Sep '15

13 Sep '15

Hello friends, okay with you? I hope you are well. I've tried to get in some mailing lists and could not. Did you could get me a question, or send me somewhere that I can study about? I rode an environment with oVirt. I have the engine running on the IP xx.xx.xx.45 and Host with the IP xx.xx.xx.46. Everything works fine, datacenter, cluster, host, storage (iSCSI). But when I create a VM, install CentOS for example. I can not access the network. I can not ping any address out. What should I do? Is there some setting I need to change? The host has two interfaces eth0 and ovirtmgmt, all working perfectly well. Could someone give me a light? Thanks in advance! Update: I have /27 (Netmask 255.255.255.224) xx.xx.xx.45 engine xx.xx.xx.46 host (vdsm) ovirtmgmt bridge xx.xx.xx.33 is my gateway Network of VM is: xx.xx.xx.52 xx.xx.xx.33 gw

multi-able nics on hypervisor
by Kyle Bassett 11 Sep '15

11 Sep '15

I have a few hypervisors that have 2 pics, up till now only one was configured with dhcp. I enabled the 2nd nic and set it to dhcp also - as soon as I do that it make the other nic “unconfigured” - even when I set it to static it marks the other “unconfigured”. Can I not have 2 interfaces configured at the same time - I am doing this from the selection menu on the hypervisor. Ideally I want one for management and the other for virtual machines. Thanks Kyle

vdsm high mem usage
by Michael Kleinpaste 11 Sep '15

11 Sep '15

Hi everybody. So I ran into that high mem usage thing. The problem I have with patching is that this is a live system so I can't do it mid day. Can anybody tell me if it is possible to just restart the vdsm service or does the host have to be in "maintenance mode" before restarting it? It is using gluster storage, if that makes a difference as well.

strange iscsi issue

------=_Part_1904412_191957680.1441657611396 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit Hi All, I have to create a test environment for testing purposes, because we need to testing our new 10gbe infrastructure. One server that have a 10gbe nic - this is the vdsm host and ovirt portal. One server that have a 10gbe nic - this is the storage. Its connected to each other throught a dlink 10gbe switch. Everything good and nice, the server can connect to storage, I can make and run VMs, but the storage performance from inside VM seems to be 1Gb/sec only. I did try the iperf command for testing connections beetwen servers, and it was 9.40 GB/sec. I have try to use hdparm -tT /dev/mapper/iscsidevice and also it was 400-450 MB/sec. I've got same result on storage server. So: - hdparm test on local storage ~ 400 mb/sec - hdparm test on ovirt node server through attached iscsi device ~ 400 Mb/sec - hdparm test from inside vm on local virtual disk - 93-102 Mb /sec The question is : Why? ps. I Have only one ovirtmgmt device, so there are no other networks. The router is only 1gbe/sec, but i've tested and the traffic does not going through this.
