Testing ovirt 3.6 Beta 3
by wodel youchi 04 Sep '15

04 Sep '15

Hi, Another test of ovirt hosted-engine on FC22 using ovirt 3.6 Beta3. VM engine is also a FC22 Problem: - No VM engine on webui Test Environment Just two machines: 1 - Machine 1 used as storage : - iscsi target with a raw file for the VM engine storage - NFS4 for other data domains 2 - Machine 2 used as hypervisor The installation went without problem, but as always, the VM engine is not present on the webui. PS: 1- I gave the VM engine just 2Gb of memory since I don't have too much RAM on hypervisor, could that be the cause of the problem? 2- This version of ovirt-hosted-engine-ha-1.3.0-0.0.master.20150424113926.20150424113923.git7c14f4c.fc22.noarch.rpm package is causing the ovirt-ha-agent to crash, it was replaced with another which I still have ovirt-hosted-engine-ha-1.3.0-0.0.master.20150820064645.20150820064642.git02529e0.fc22.noarch.rpm, but it's not present on the repository, I had to update the package manually at the end of ovirt-hosted-engine-setup installation.

Problem with kerberos authentication and ovirt-engine-sdk-python
by 79160810031＠yandex.ru 04 Sep '15

04 Sep '15

Hello. I have problem with kerberos authentication. I use ovirt-engine-sdk-python from https://github.com/oVirt/ovirt-engine-sdk.git. I have RHEL manager and IPA server. I created a virtual machine and installed RedHat 7.0 on the vm. I did command ipa-client-install on this vm. Command id diplayed a valid value for user admin. I got with wget ca.crt file from manager. When I executed following commands: api = API(url="https://rhevm.dev.ru/ovirt-engine/api", username="admin(a)dev.ru", password="something", ca_file = "/tmp/ca.crt") that's all correct. I got api and I could use this api. Then: I cloned git repo git clone https://github.com/oVirt/ovirt-engine-sdk.git created ovirt-engine-sdk-python rpm with kerberos authentication support. make rpm installed this package on my vm. rpm -ihv ovirt-engine-sdk-python-4.0.0.0-0.1.el7.noarch.rpm I got kerberos ticket: kinit admin klist displayed that is valid ticket. And when I executed following commands: api = API(url="https://rhevm.dev.ru/ovirt-engine/api", kerberos = True, ca_file = "/tmp/ca.crt") I got error 401 Unauthorized. Is what is incorrect? Redhat 7.0, RHEL 3.5

ovirt 3.5 engine web certificate
by Baptiste Agasse 04 Sep '15

04 Sep '15

Hi all, I've followed the procedure to replace self signed certificate to one issued by our internal PKI to avoid security failure when users access to the webui (https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualiza…) The connection to the webui now works fine without any security warning (the internal PKI CA is in the trusted CA of our clients OS). But on the other hand, i've some troubles: * I've to specify the --ca-file option for ovirt-shell and engine-iso-uploader (i didn't test the engine-image-upload command), it will be nice if the documentation provide a way to replace this by default (or use the trusted ca store of the OS ?). This is not a bug just some feedback on the certificate change procedure that don't cover these side effects. * I can't add new ovirt-node anymore. The ovirt-hosted-engine --deploy fails on new nodes with an SSL error. To workaround this i've to modify the file "/usr/lib/python2.7/site-packages/ovirtsdk/web/connection.py" around line 233 to make an insecure connection to the engine and add the new node. I didn't have tested to add a new node from the ovirt engine cli/webui but i think it will be the same issue because the error occurs on the vdsm activation that is common to the 'new hosted engine node' and 'new node' deployment. I've seen https://bugzilla.redhat.com/show_bug.cgi?id=1059952 but the workaround noted in the comment #8 didn't work for me. Someone have more info on this issue or have the same problem ? This deployment is on ovirt 3.5.3, CentOS 7 (engine and nodes). Have a nice day. Regards. -- Baptiste

ovirt+gluster+NFS : storage hicups
by Nicolas Ecarnot 03 Sep '15

03 Sep '15

Hi, I used the two links below to setup a test DC : http://community.redhat.com/blog/2014/05/ovirt-3-4-glusterized/ http://community.redhat.com/blog/2014/11/up-and-running-with-ovirt-3-5-part… The only thing I did different is I did not usea hosted engine, but I dedicated a solid server for that. So I have one engine (CentOS 6.6), and 3 hosts (CentOS 7.0) As in the doc above, my 3 hosts are publishing 300 Go of replicated gluster storage, above which ctdb is managing a floating virtual ip that is used by NFS as the master storage domain. The last point is that the manager is also presenting a NFS storage I'm using as an export domain. It took me some time to plug all this setup as it is a bit more complicated as my other DC with a real SAN and no gluster, but it is eventually working (I can run VMs, migrate them...) I have made many severe tests (from a very dumb user point of view : unplug/replug the power cable of this server - does ctdb floats the vIP? does gluster self-heals?, does the VM restart?...) When precisely looking each layer one by one, all seems to be correct : ctdb is fast at managing the ip, NFS is OK, gluster seems to reconstruct, fencing eventually worked with the lanplus workaround, and so on... But from times to times, there seem to appear a severe hicup which I have great difficulties to diagnose. The messages in the web gui are not very precise, and not consistent: - some tell about some host having network issues, but I can ping it from every place it needs to be reached (especially from the SPM and the manager) "On host serv-vm-al01, Error: Network error during communication with the Host" - some tell that some volume is degraded, when it's not (gluster commands are showing no issue. Even the oVirt tab about the volumes are all green) - "Host serv-vm-al03 cannot access the Storage Domain(s) <UNKNOWN> attached to the Data Center" Just by waiting a couple of seconds lead to a self heal with no action. - Repeated "Detected change in status of brick serv-vm-al03:/gluster/data/brick of volume data from DOWN to UP." but absolutely no action is made on this filesystem. At this time, zero VM is running in this test datacenter, and no action is made on the hosts. Though, I see some looping errors coming and going, and I find no way to diagnose. Amongst the *actions* that I had the idea to use to solve some issues : - I've found that trying to force the self-healing, and playing with gluster commands had no effect - I've found that playing with gluster adviced actions "find /gluster -exec stat {} \; ..." seem to have no either effect - I've found that forcing ctdb to move the vIp ("ctdb stop, ctdb continue") DID SOLVE most of these issue. I believe that it's not what ctdb is doing that helps, but maybe one of its shell hook that is cleaning some troubles? As this setup is complexe, I don't ask anyone a silver bullet, but maybe you may know which layer is the most fragile, and which one I should look at more closely? -- Nicolas ECARNOT
