I am using NFS share on an Openfile server as my main datastore went to fire up a virtual instance this is the error I get: VM Building_Automation is down. Exit message internal error process exited while connecting to monitor: qemu-kvm: -drive file=/rhev/data-center/c10c25e0-526a-11e1-a5e4-87fa674ffb5d/340dad49-2ec7-475e-b6c6-668504bdb5b1/images/da582689-2248-4d0e-a017-b09f8cfa9410/78340ab7-b1f5-4fad-9150-437e7ff9d14c,if=none,id=drive-virtio-disk0,format=raw,serial=0e-a017-b09f8cfa9410,cache=none,werror=stop,rerror=stop,aio=threads: could not open disk image /rhev/data-center/c10c25e0-526a-11e1-a5e4-87fa674ffb5d/340dad49-2ec7-475e-b6c6-668504bdb5b1/images/da582689-2248-4d0e-a017-b09f8cfa9410/78340ab7-b1f5-4fad-9150-437e7ff9d14c: Permission denied . Does vdsm have to be installed on the server that shares the main datastore? Export and ISO are fine no problems. -- Dominic Kaiser Greater Boston Vineyard Director of Operations cell: 617-230-1412 fax: 617-252-0238 email: dominic(a)bostonvineyard.org

Re: [Users] Pxeboot - pwd/login issue
by Li, David 13 Feb '12

Hi Mike, I ran into the login/pwd problem again with this new build. Kernel option adminpw worked but only for a short time. I was asked to change pwd immediately after login but then rejected again after I did that. There was an short-lived error message on the screen but I wasn't able to capture it. I tried the latest from archipel source and it worked without password issue. I pulled it from: git clone https://github.com/primalmotion/Archipel.git There might be a few updates right after you pulled it last time. Would you mind merge the new updates into ovirt node again? Thanks.

[Users] Difference between RHEV and ovirt
by patrick 13 Feb '12

13 Feb '12

Hello all, In our company we want to use either RHEV or oVirt in a production environment. After testing RHEV for 30 days we are happy with the stability and features. Can someone explain the difference between RHEV and oVirt? Are there maybe some features just available in RHEV like Windows guest drivers or someting like that? I'm not sure if I get this right, but as oVirt is the upstream of RHEV does this means that new features like hot add nic etc. are first available in oVirt and afterwards in RHEV. Does oVirt has any drawbacks compared to RHEV other than support? Thanks in advance Patrick van der Wiel

[Users] Problem with required packages when installing ovirt-engine
by Terry Phelps 13 Feb '12

13 Feb '12

I'm new here, and am trying to install ovirt-engine, as documented on ovirt.org/get-ovirt, and in the installation guide. I've worked with RPM-based distributions (RHEL, Centos, Scientific Linux) for quite a while, but have never worked with Fedora. Please tell me what I'm doing wrong, or failing to do: I am trying to install ovirt-engine on a newly-built Scientific Linux 6.1 (just like RHEL 6.1) machine. I did the "wget ...ovirt-engine.repo", and removed the classpathx-jaf RPM. Then I tried to "yum install ovirt-engine", and got a number of errors: Error: Package: ovirt-engine-tools-common-3.0.0_0001-1.6.fc16.x86_64 (ovirt-engine-stable) Requires: jakarta-commons-jxpath Error: Package: ovirt-engine-log-collector-3.0.0_0001-1.6.fc16.x86_64 (ovirt-engine-stable) Requires: python(abi) = 2.7 Installed: python-2.6.6-20.el6.x86_64 (@anaconda-ScientificLinux-201107271550.x86_64) python(abi) = 2.6 Error: Package: ovirt-engine-tools-common-3.0.0_0001-1.6.fc16.x86_64 (ovirt-engine-stable) Requires: jakarta-commons-configuration Error: Package: ovirt-engine-jboss-deps-3.0.0_0001-1.6.fc16.x86_64 (ovirt-engine-stable) Requires: hsqldb >= 1:1.8.0.10-9 Installed: 1:hsqldb-1.8.0.10-8.el6.x86_64 (@anaconda-ScientificLinux-201107271550.x86_64) hsqldb = 1:1.8.0.10-8.el6 Error: Package: ovirt-engine-3.0.0_0001-1.6.fc16.x86_64 (ovirt-engine-stable) Requires: libc.so.6(GLIBC_2.14)(64bit) Error: Package: ovirt-engine-jboss-deps-3.0.0_0001-1.6.fc16.x86_64 (ovirt-engine-stable) Requires: jakarta-commons-discovery >= 1:0.4-7 Installed: 1:jakarta-commons-discovery-0.4-5.4.el6.noarch (@anaconda-ScientificLinux-201107271550.x86_64) I'm suppose this means that I need newer versions of some packages that are installed now, and these are not available in a yum repo that my yum can see. The only change to the installed yum environment I have made is to add the ovirt-engine repo. I don't see anything in the docs about pointing to some Fedora repo, or some such thing, but perhaps that's what I need to do. Can someone please enlighten me?

[Users] Ovirt Support life (timeframe) - upgrade path ?
by Morgan Cox 13 Feb '12

13 Feb '12

Hi. As Fedora the default system that Ovirt is packaged for does this mean that Ovirt will have the same (short) support life of 18 months ? I ask as that is a bit short to have in enterprise .. I.e if I install Ovirt in Fedora 16 will support life run out when Fedora 16 runs out or will I be able to upgrade Ovirt/Fedora to the next version? Are there going packages for Centos ? If so will they be supported longer ? If this information is out there already can you point me to the right direction ? Regards

[Users] Two fence devices per server.
by Nathan Stratton 12 Feb '12

12 Feb '12

Just installed the latest oVirt, must admit you guys have done a great job. One issue I am having tho is that with my setup each server has 2 power supplies and the two supplies are one two different APC power strips. Is there any way to configure fencing to work with two devices per server? ><> Nathan Stratton CTO, BlinkMind, Inc. nathan at robotics.net nathan at blinkmind.com http://www.robotics.net http://www.blinkmind.com

[Users] Unable to add ISOs to default ISO storage domain
by Andrew Dunlop 12 Feb '12

12 Feb '12

I have been trying to upload ISOs onto my ISO Storage Domain, set up when I ran engine-setup. I can run the command and the .iso file is correctly put in place, however this never appears in the available images for this domain on the web-admin. I notice that there are no file entries in https://xxxx.xxxx.co.uk:8443/api/storagedomains/a677acff-601b-4b6d-86ce-079… just what is given in the verbose output from the uploader. Any ideas what the problem might be? I have tried a couple of ISOs and have also done a cleanup and setup. Below is the verbose output from the uploader: [admin@xxxx ~]$ sudo engine-iso-uploader -v -f -i ISOs upload Downloads/TinyCore-current.iso [sudo] password for admin: Please provide the REST API password for the admin@internal oVirt Engine user (CTRL+D to abort): DEBUG: URL is https://xxxx.xxxx.co.uk:8443/api/storagedomains?search=name%3DISOs DEBUG: Returned XML is <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <storage_domains> <storage_domain href="/api/storagedomains/a677acff-601b-4b6d-86ce-0798f3833629" id="a677acff-601b-4b6d-86ce-0798f3833629"> <name>ISOs</name> <link href="/api/storagedomains/a677acff-601b-4b6d-86ce-0798f3833629/permissions" rel="permissions"/> <link href="/api/storagedomains/a677acff-601b-4b6d-86ce-0798f3833629/files" rel="files"/> <type>iso</type> <master>false</master> <storage> <type>nfs</type>srmr <address>xxxx.xxxx.co.uk</address> <path>/isos</path> </storage>users@ <available>48318382080</available> <used>4294967296</used> <committed>0</committed> <storage_format>v1</storage_format> </storage_domain> </storage_domains> DEBUG: id=a677acff-601b-4b6d-86ce-0798f3833629 address=xxxx.xxxx.co.uk path=/isos DEBUG: local NFS mount point is /tmp/tmpX03eVj DEBUG: NFS mount command (/bin/mount -t nfs -o rw,sync,soft xxxx.xxxx.co.uk:/isos /tmp/tmpX03eVj) DEBUG: /bin/mount -t nfs -o rw,sync,soft xxxx.xxxx.co.uk:/isos /tmp/tmpX03eVj DEBUG: _cmds(['/bin/mount', '-t', 'nfs', '-o', 'rw,sync,soft', 'xxxx.xxxx.co.uk:/isos', '/tmp/tmpX03eVj']) DEBUG: returncode(0) DEBUG: STDOUT() DEBUG: STDERR() DEBUG: Size of Downloads/TinyCore-current.iso: 12507136 bytes 12214.0 1K-blocks 11.0 MB DEBUG: Available space in /tmp/tmpX03eVj/a677acff-601b-4b6d-86ce-0798f3833629/images/11111111-1111-1111-1111-111111111111: 48557457408 bytes 47419392.0 1K-blocks 46308.0 MB DEBUG: euid(0) egid(0) DEBUG: euid(0) egid(0) DEBUG: URL is https://xxxx.xxxx.co.uk:8443/api/storagedomains/a677acff-601b-4b6d-86ce-079… DEBUG: Returned XML is <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <files/> DEBUG: /bin/umount -t nfs -f /tmp/tmpX03eVj DEBUG: /bin/umount -t nfs -f /tmp/tmpX03eVj DEBUG: _cmds(['/bin/umount', '-t', 'nfs', '-f', '/tmp/tmpX03eVj']) DEBUG: returncode(0) DEBUG: STDOUT() DEBUG: STDERR()

[Users] Gluster Compatibility
by Barry French 11 Feb '12

Hi, Is oVirt able to use glusterfs to access gluster shares. I know gluster can export NFS shares but using the glusterfs client provides redundancy over all gluster brick ip's, whereas standard NFS does not. Thanks.

[Users] Possible to migrate from an existing KVM/Libvirt VM (installed in an LVM) ?
by Morgan Cox 10 Feb '12

10 Feb '12

Hi Can an existing KVM/Libvirt VM (installed in an LVM) ever be migrated to an Ovirt node (offline migration is ok.) ? Also - when Ovirt is released - what OS is the going to be used for .iso for the node - i.e it is going to be based on Fedora or RHEL (centos) ? (i know you can get packages for other os's) Regards
