4.1 to 4.2 upgrade
by Charles Kozler 15 Oct '17

15 Oct '17

hello, What would be the process to go from current 4.1 to 4.2-pre? I have been demoing 4.2 on my own lab environment and the WebUI, for my user base, is entirely more intuitive than the previous My 4.1 is relatively new so there isnt much config done to it, that said, wondering what it would take to update ovirt HE w/ 3 nodes + GlusterFS (not managed via ovirt) to 4.2-pre and what it would like like to move back from a -pre channel to mainline Alternatively, I could wait for 4.2 to go main, do you have an estimated date for that? Thanks!

Configuring ilo4 on hp blade gen 9
by Gianluca Cecchi 15 Oct '17

15 Oct '17

Hello, on 4.1.6 I'm configuring fencing on HP blades Gen9. It seems I'm able to use ilo_ssh as agent and that I have only to set 22 as the port and ssh=1 in options Question: why ssh=1??? the agent is named ilo_ssh.... shouldn't be obvious??? The same form command line I MUST set -x even if I use fence_ilo_ssh command Nevertheless, this way I get successful test Sometimes I don't get the same result if I run from shell eg: fence_ilo_ssh -a ilo_ip -l fenceuser -S /usr/local/bin/my_fence_script.sh -x -o status I get sometimes: Unable to connect/login to fencing device I think it could be some sort of delay timeout. In fence_ilo_ssh I see these kinds of timeouts in help --power-timeout=[seconds] Test X seconds for status change after ON/OFF --shell-timeout=[seconds] Wait X seconds for cmd prompt after issuing command --login-timeout=[seconds] Wait X seconds for cmd prompt after login --power-wait=[seconds] Wait X seconds after issuing ON/OFF --delay=[seconds] Wait X seconds before fencing is started How do they map with gui settings options in case I would use some of them? Also, how do I map the command line option -4, --inet4-only Perhaps inet4_only=1 ? I see that ssh=1,inet4_only=1 works but also ssh=1,inet4_only=1,foo=1 works So it is not a reliable test to verify syntax... All in all do you think it is the best agent for ilo4 based blades? I have made some test with fence_ilo4 but unable to get success... what should I enable on ilo web administration page in this case, if you think the agent would be better for any reason? Thanks, Gianluca

How to change network card configuration under bridge on host?
by Derek Atkins 13 Oct '17

13 Oct '17

Hi, I've got a single host running CentOS 7.3 + Ovirt 4.0.6 with hosted engine. I'm having network issues (see previous email thread) and the next thing I'm going to try is to add a new network card and use that instead of the onboard ethernet on the mobo. However it looks like /etc/sysconfig/network-scripts/ifcfg-* get replaced every time the host restarts. Right now it's configured with: eno1, eno2 -> bond0 -> ovirtmgmt I accomplished this by setting up the bond by hand on the host before I installed the hosted engine, but then ovirt "took control" of the configuration. I want to change this to replace eno1 and eno2 with the two new devices when I add the new card tomorrow. What's the best way to do this? I suppose I can just add the new devices as bond0 slaves pretty easily by creating new ifcfg-xxx files for the new devices (I'm assuming they will be eno3 and eno4) that looks similar to the eno1 and eno2 files. However I'd like to also remove eno1 and eno2 from bond0. Yet I suspect if I change ifcfg-eno1 and ifcfg-eno2 by hand, they will just get replaced at the next reboot by ovirt. How do I convince ovirt to stop overwriting those files? Or how do I tell ovirt about the new configuration?

Issues with Windows 7 VM
by Marc Turner 12 Oct '17

12 Oct '17

Hello, I'm a Systems Administrator at Wolfram Research, and we've been having an issue with a Windows 7 x64 VM. This is a new VM with a newly created Cinder VM image attached to it, which was working without issue last week. Earlier today I performed a Windows update and shutdown the VM. When trying to start it back up, it does nothing but fail with the message "Failed to start VM on host. We have several VM hosts set up, so it will bounce around between a few of them, failing each time before giving up entirely. Myself and another SysAdmin have looked through the logs and have not been able to find any reason as to why this VM won't start. No other VM's are having problems, and Cinder is working correctly. If you would have any idea as to why this is happening, or where we could look to figure out what may be going on, it would be much appreciated. Thank you, Marc Turner Systems Administrator Wolfram Research
