[Users] Restirct list of AD servers
by Keith Mitchell 18 Feb '13

18 Feb '13

I have a situation where the Active Directory domain I am trying to use as authentication for ovirt lists many servers all around the world. But... my server running ovirt is sitting behind a firewall that doesn't allow me to access all of them... only the local ones. We do have a "locater dns record" which we can query at a well known name and it will always return the local ip address of the AD server... but if you query the SRV records for the domain it will return all of the servers. I was able to add the domain using engine-manage-domains, and I tweaked the /etc/ovirt-engine/krb5.conf to only include the local AD servers where we can access, but that doesn't seem to be sufficient. Not sure if ovirt is querying the dns records on boot to get the list of servers to talk to or not, but it doesn't seem to be using /etc/ovirt-engine/krb.conf for this purpose. So... is there anyway to manually force it to use a certain server and not have it query dns? thanks.

[Users] Failing on new setup

This is a multi-part message in MIME format. --------------040901050807070502000602 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Hi guys, New to oVirt - and "new" to Fedora after a *very long* break @ using Debian/Ubuntu almost exclusively for the last few years. Much has changed, so please pardon my ignorance - got some catching-up to do. I'm doing PoC of a number of systems, so need to give oVirt a fair shake, but I'm tripping up before I can even get going (does not bode well). I've tried following the QuickStart, all-in-one & other guides, & quickly came across issues. Next I'll have to start building from source - a prospect that will by no means present me with less issues. New F18, minimal headless server. Installed via yum as documented, but install failed at the last steps, as there seems to be an issue with the scripts' implementation of firewalld. A very nice chap @ the IRC channel managed to help be out to get over that initial hurdle - had to *completely* disable firewalld & select the 'None' option for the setup. (seems like a really bad idea to start off like that - disabling security - but this is a lab PoC, so OK, will let it slide for now) I've also disabled SELinux & IPtables via systemctl - so that we can eliminate that as an issue. Script(s) still don't complete without issue, but at lease the engine seems to come up & I can log in. After logging in, I try to (re)connect to the local hypervisor via (root@) $FQDN, localhost & 127.0.0.1, but it fails to come up (why root? OK....). It adds the host, but there seems to be connectivity issues. I'm seeing this in the GUI events: Host localhost installation failed.

I have installed Ovirt 3.1 on a Fedora 17 server, and would like to upgrade to Fedora 18... The documentation I have found on the mailing list is unclear on how to do this. Does anyone have any pointers on how this can be done.. as well as upgrading to Ovirt 3.2 after we've upgraded to Fedora 18 Thanks In advance

[Users] Access libvirt/virsh on oVirt node
by Frank Wall 17 Feb '13

17 Feb '13

Hi, how can I access libvirt/virsh on oVirt node? What are the credentials for accessing libvirt/virsh on the command line of a oVirt node? virsh # list Please enter your authentication name: Please enter your password: error: Failed to reconnect to the hypervisor error: no valid connection error: authentication failed: Failed to step SASL negotiation: -1 (SASL(-1): generic failure: All-whitespace username.) It would make debugging things much easier... Thanks - Frank

[Users] fedora-18 host deploy regression
by Alon Bar-Lev 16 Feb '13

16 Feb '13

Hello, Since the release of fedora-18, there are some regressions related to tuned package. It is regression compared to Beta. tuned service does not start because of various reasons[1][2][3]. One option is to drop tuned usage, another is to push fedora into fixing these. A fix for [3] is available, but has not been pushed yet. Regards, Alon [1] https://bugzilla.redhat.com/show_bug.cgi?id=883421 [2] https://bugzilla.redhat.com/show_bug.cgi?id=885271 [3] https://bugzilla.redhat.com/show_bug.cgi?id=909445

[Users] Host deployment on 3.2
by Jeff Bailey 16 Feb '13

16 Feb '13

I've hit a couple of small problems deploying an F18 minimal host with 3.2. The first problem was missing tar. Second, I had manually set up a vlan on the host for initial communication and the regular expression in bridge.py of the otopi plugin couldn't determine the vlan id. After tweeking it a bit to make it similar to _RE_VLAN_DEVICE it was fine. --- Jeff

[Users] F18 iSCSI/FC and latest systemd/udev
by Jeff Bailey 16 Feb '13

16 Feb '13

While not an actual problem with oVirt, the latest systemd/udev packages for F18 (197-1) break permissions on LVM volumes and stop vdsm/qemu/etc from accessing them. I just downgraded them and everything seems OK but I thought I'd let people know (easier to just avoid rather than repair :) ). There's a bugzilla for it from a week or two ago but since 3.2 came out I figured a lot more people might be installing it on new F18 installations with all the updates and running into problems.

[Users] Move single vmdk (or else) disk into oVirt/RHEV
by Nicolas Ecarnot 16 Feb '13

16 Feb '13

Hi, I find it hard to find any information about the way I have to follow to convert/import a vmdk/qcow/raw/etc... single disk into an oVirt disks list. I know how to use virt-v2v to import complete VMs (disk AND config), but don't know how to handle a single data disk. Regards, -- Nicolas Ecarnot
