Hi folks, After I shut down my ovirt-manager and the KVM (+vdsm) nodes and restarted them my DB in the manager gave me errors... do we need to follow some specific procedure while restarting the whole setup ? -- Regards, Rahul

[Users] Configuring MTU
by Nathan Stratton 02 Apr '12

Is there a way to configure MTU on a guest by guest basis? All our bond interfaces are configured as 9000 byte MTU, but we have a few guests that don't support that and need 1500 byte setting. -Nathan

[Users] (potential bug) After I create a virtual disk I am unable to start a VM - Permissions issue ? The node seems to have no write access to the directory on the NFS server...
by Morgan Cox 29 Mar '12

29 Mar '12

Hi. Still not actually managed to test a vm... I can start a VM (and use spice) without a virtual disk. However as soon as I add a virtual disk the VM no longer starts example error message ------------------------------------------------------------------------------------------------------------------- VM ddf is down. Exit message internal error process exited while connecting to monitor: qemu-kvm: -drive file=/rhev/data-center/b2b2e054-66b2-11e1-bda3-1728f784de9e/2f7ee7bc-09b3-42ba-af91-40d79293e360/images/c507a2bc-38c5-498e-88c0-7cce8169cf67/6c36c8e4-6618-42f3-9cc4-06d2bccdc9cf,if=none,id=drive-virtio-disk0,format=raw,serial=c507a2bc-38c5-498e-88c0-7cce8169cf67,cache=none,werror=stop,rerror=stop,aio=threads: could not open disk image /rhev/data-center/b2b2e054-66b2-11e1-bda3-1728f784de9e/2f7ee7bc-09b3-42ba-af91-40d79293e360/images/c507a2bc-38c5-498e-88c0-7cce8169cf67/6c36c8e4-6618-42f3-9cc4-06d2bccdc9cf: Permission denied . ------------------------------------------------------------------------------------------------------------------- I have noticed that the directory /rhev/data-center/b2b2e054-66b2-11e1-bda3-1728f784de9e/ is not writable via the ovirt node server. I am using a separate NFS server for storage. Is this a bug ? Does anyone know how to fix this ? shall I report it ? Many regards !

[Users] Ovirt Node - tls VM Migration Fails
by David Elliott 29 Mar '12

29 Mar '12

Hi I'm ovirt node using the latest ovirt-node-iso-2.3.0-1.0.fc16.iso, and having a problem with live migration After fresh install of node /etc/libvirt/libvirtd.conf listen_tls = 0 listen_tcp = 1 # tcp and tls ports are defaults # tls_port = "16514" #tcp_port = "16509" [root@ovirt-h-6 ~]# netstat -ant |grep -E "16514|16509" tcp 0 0 0.0.0.0:16509 0.0.0.0:* LISTEN iptables is set to accept ALL When migration is attempted - it then tries and fails to use tls 2012-03-28 18:33:15.566+0000: 1622: error : doPeer2PeerMigrate:2129 : operation failed: Failed to connect to remote libvirt URI qemu+tls://192.168.192.230/system - manually configuring a registered/running node with listen_tls = 1, migration will then succeed - editing the live-cd and setting "listen_tls=1" , a fresh install then has some problems libvirtd fails to start on install due to a certificate error (which am guessing is installed as part of the node registration process with the engine) "Cannot read CA Certifcate /etc/pki/CA/cacert.pem" This also causes the setting of hostname/network details to fail during the automated installation; so this seems the wrong way to go I'm not sure if the problem here is live migration shouldn't be using tls; or that the node registration process should set "listen_tls=1" l; but isn't Any assistance appreciated Cheers, Dave ______________________________________________________________________ This email has been scanned by the Symantec Email Security.cloud service.

[Users] New to oVirt, I've got a couple of questions.

> This message is in MIME format. Since your mail reader does not understand this format, some or all of this message may not be legible. --B_3415796945_58591741 Content-type: text/plain; charset="US-ASCII" Content-transfer-encoding: 7bit Hi Folks, I've got oVirt 3.0 installed on a Fedora 16 machine, and I'm planning my data center. Great process, by the way, very straight forward. I'll have two host machines (on order) which I'll likely load with the oVirt image. These two hosts each will have a large amount of RAID 5 local storage. Here's my questions.. Storage: If I'm using this local storage on each host, will I be able to migrate VM's from host A to host B if needed, or does storage need to be shared. I guess another way of asking the question is, what's the best way for me to set this up? :) Networking: When I set up a logical network, how is that accessed from the physical network? For example, if my physical network is 192.168.1.0, and my logical network is 155.223.44.0, how will I connect to port 80 on a virtual machine with the IP 155.223.44.5 from IP 192.168.1.10. Is there port forwarding? I didn't see mention of it in the guide.

[Users] OVirt in production
by Garth Keesler 29 Mar '12

29 Mar '12

I've seen a thread where OV is discussed as a feature test platform in the same vein as FC. That raises the question, for me at least, as to whether or not I should deploy OV in a production environment where it will host continuous build VMs in support of Agile Teams of developers. It looks really good but not if a new version comes out every six months or so and I have to do a reinstall. If it is a new feature platform, will easy (spelled "single-click" or something close to it) upgrading be supported? Thanx, Garth

[Users] engine admin ui deltas
by Ryan Harper 29 Mar '12

29 Mar '12

When I go to configure a storage domain in the admin interface if I click on the Storage link (in the tree pane: System->Default->Storage) and attempt to add a new domain, the only type that is available is Data / NFS. However, if I Click on Default (in the tree pane) and then select "Default" DataCenter, and then Select the Storage tab at the top, and create a New Domain from there, I can choose ISO domain... ? In a similar vein, when I attempt to move a storage domain in/out of maint or removal, going in via the Storage link the tree pane doesn't allow you to select those options, but going through the selected Datacenter Storage tab does.. I suppose I just need a bit more muscle memory, but I've been doing this UI operations infrequent enough that I forget the right path. -- Ryan Harper Software Engineer; Linux Technology Center IBM Corp., Austin, Tx ryanh(a)us.ibm.com
