Re: [Users] where do bond interfaces come from when adding a node that is FC17

Where does the bonding information get stored? It doesn't seem to be in /etc/sysconfig/network-scripts? The bonding devices are created dynamically when vdsmd starts. The reason I ask, is I have two nodes one of which has the bonding interfaces up and the other which doesn't. The one that doesn't have the bonding interfaces up is failing to be added to the ovirt node list. I am not sure how the failure of adding host is related to bonding interfaces. You could check the log /tmp/vds_bootstrap.xx.log and /tmp/vds_installer.xx.log during node installation. Why doesn't vdsm write its log files to /var/log/vdsm where people would expect them to be? I think writing this to /tmp is a really bad habit that should be fixed sooner rather than later especially given the importance of the logs when something goes wrong.

I think of it like this: OpenStack is / aims to be an open source Amazon Web Services (EC2, S3, etc.), oVirt is / aims to be an open source vSphere. The former tends toward more automation, the latter toward more flexibility. There's a good deal of overlap though. That's my take, I'm interested to hear others' viewpoints. Also, I've seen Kyle Mestery blog on the topic: http://www.siliconloons.com/?p=179. I think both technologies are very complementary. OpenStack currently currently has no good management interface and I look at oVirt as mostly a cloud management interface. I can see a future in which oVirt is used to manage a bunch of openstack nodes. Quantum integration is already happening and User management is already external to oVirt so keystone can probably plugged in there at some point. Then either vdsm needs to learn to talk to nova or oVirt needs to learn to talk to nova as an alternative to vdsm.

I really think it would be a good idea for the oVirt Node team to add in some persistent script files that are run at various points in the boot process so that people like me can add in hacks where needed to make it work.

[Users] Guest life-cycle
Hi, after being able to start my first guest I noticed two things: 1) When I started the guest with the run once option the console button didn't become available. Navigating to another section of the GUI and back didn't help. I was only able to make is available by closing the browser tab and then going to the admin portal again from scratch. 2) When my guest froze (due to nested virtualization experimentation that apparently doesn't work yet) I had no (obvious) way to kill the vm. Hitting the stop button apparently only sends a shutdown command but I couldn't find any way to issue a destroy command. After killing the qemu process on the host manually the guest in the portal gui apparently went into an unknown ? state which isn't surprising but now there seems to be no way to get rid of the vm. What is proper way to get rid of such a misbehaving guest? Regards, Dennis ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

[Users] cannot install node iso images
Hi, I just tried installing the 2.3.0 node iso images from http://ovirt.org/releases/nightly/binary/ in a VM on a Fedora 17 Host and failed. First the image takes 1-2 minutes to boot and I'm not sure why it would take so long. There is not output made so it's hard to say what's going on even when you press esc the skip the plymouth progress bar. Second after that I get quite a few errors about denied permissions and read-only filesystems. For example systemd tries to create /var/log/wtmp but fails with permission denied and it tries to remove /var/lib/rpm/__db.00* files which gets a read-only filesystem error. Third once it actually gets to the Install hypervisor TUI this interface does not respond to key presses. When I press the cursor keys I only get text like ^[[C plastered on the screen. Actually starting the installation is impossible. What am I doing wrong? Regards, Dennis ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
