what is the error message you get when you try to put the host in maintenance? are there any running vm's reported? Try to press the "confirm host has been rebooted" button and than see if you can put the host in maintenance. If that fails, select the host, in the general tab you will get the re-install link. try to re-install, when install fails the host should change status to failed installation.

Re-add a node

Hi, I don know i the subject is explicit enough but I have a problem and I hope to find some help here. I had two hosts in my cluster (node1 and node2). I had to reinstall node1 due to some networks problem. In the engine, node1 appears now "Not reponsive" and I can't remove it from the engine ui. Now node1 is back and I want to add it in the cluster but I can't. I've got this error (vdsm.log) : BindingXMLRPC::ERROR::2014-04-11 01:04:42,622::BindingXMLRPC::81::vds::(threaded_start) xml-rpc handler exception Traceback (most recent call last): File "/usr/share/vdsm/BindingXMLRPC.py", line 77, in threaded_start self.server.handle_request() File "/usr/lib64/python2.6/SocketServer.py", line 278, in handle_request self._handle_request_noblock() File "/usr/lib64/python2.6/SocketServer.py", line 288, in _handle_request_noblock request, client_address = self.get_request() File "/usr/lib64/python2.6/SocketServer.py", line 456, in get_request return self.socket.accept() File "/usr/lib64/python2.6/site-packages/vdsm/SecureXMLRPCServer.py", line 136, in accept raise SSL.SSLError("%s, client %s" % (e, address[0])) SSLError: sslv3 alert certificate unknown, client 192.168.1.100 192.168.1.100 is the engine's address Can somebody help me ?

live migration and snapshot problem

------=_Part_3341144_1822521101.1397149161768 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit Dear members, We made a test plaform for testing ovirt 3.4 features. We got four amd x2 4400+ machine with 2 gigs of ram and build a gluster based cluster. I set up an amd-G2 based cluster. I rebuild and installed the qemu-kvm-rhev package ( http://ftp.redhat.com/redhat/linux/enterprise/6Server/en/RHEV/SRPMS/qemu-kv… ) . The data storage is a "four brick" distributed-replicated gluster storage. I got a virtual machine (centos 6.5) from the ovirt's openstack based template repository. Everything was good, the vm can run on any host, but the live migration doesn't work. Also, the snapshot feature is lost from menu. I can make live snapshot, but it doesn't show on the panel. So: - I lost the snapshots:) - the live migration doesn't work. Can anyone help me? Thanks in advance.

Ok, Thanx already for all the help. I adapted some things for quicker respons: engine-config --get FenceQuietTimeBetweenOperationsInSec-->180 engine-config --set FenceQuietTimeBetweenOperationsInSec=60 engine-config --get StorageDomainFalureTimeoutInMinutes-->180 engine-config --set StorageDomainFalureTimeoutInMinutes=1 engine-config --get SpmCommandFailOverRetries-->5 engine-config --set SpmCommandFailOverRetries engine-config --get SPMFailOverAttempts-->3 engine-config --set SPMFailOverAttempts=1 engine-config --get NumberOfFailedRunsOnVds-->3 engine-config --set NumberOfFailedRunsOnVds=1 engine-config --get vdsTimeout-->180 engine-config --set vdsTimeout=30 engine-config --get VDSAttemptsToResetCount-->2 engine-config --set VDSAttemptsToResetCount=1 engine-config --get TimeoutToResetVdsInSeconds-->60 engine-config --set TimeoutToResetVdsInSeconds=30 Now the result of this is that when the VM is not running on the SPM that it will migrate before going in pause mode. But when we tried it, when the vm is running on the SPM, it get's in paused mode (for safety reasons, I know ;-) ). And stays there until the host gets MANUALLY fenced by rebooting it. So now my question is... How can I make the hypervisor fence (so reboots, so vm is moved) quicker?

[Users] using cloud-init?
by Jason Brooks 11 Apr '14

11 Apr '14

Hi all -- I've been trying, without success, to use cloud-init w/ oVirt 3.4 on Fedora 19 hosts. I've had similar failure in the past, but here are the steps I'm taking currently: 1. Import as template F19 image from ovirt-image-repository glance repo 2. Create new vm based on that template 3. Choose ovirtmgmt as the nic1 for the VM 4. Show advanced options, click initial run, expand authentication, enter a root password, paste my public key into the allowed ssh keys field 5. Hit OK, and then run the VM 6. In the VM's console, I see it complain about No instance datasource found 7. Unsurprisingly, I can't log in w/ pw or ssh. (By the way, are there any default creds for these images? I thought they might be based on the fedora cloud images, but their default uname fedora pw nothing doesn't work) I've tried some other derivations of this, launching from the Run Once menu, filling in various different fields, etc. Any clues? I don't see many people complaining about this, so I'm assuming it's working for other people. I don't know, maybe it's something with Fedora? Thanks, Jason

Regenerating new SSL certificates for ovirt-engine
by Trey Dockendorf 11 Apr '14

11 Apr '14

Given the recent OpenSSL heartbleed vulnerability, I would like to regenerate the certificates used by my ovirt-engine server. What are the steps to regenerate the certificates, and which certificates should be regenerated? My ovirt-engine host is on our campus LAN, which offers no real protection, so I would consider it public facing despite not being routable across the WAN. At minimum I'd like to regenerate the certificates used by Apache. I'd be happy to document this on the wiki, as the only items I could find were related to host renaming. Thanks, - Trey
