[Users] Low cost OOB management device

08 Oct '13

Hello, I would like to try ovirt powermanagement. I have no ILO so I would like to buy some power management device. Since it is a test I would like to stay in 100 euro range. Is it possible? Thanks, Mario

[Users] upgrade bug(?) 3.1->3.3
by Jim Kinney 07 Oct '13

07 Oct '13

I just upgraded from engine 3.1 to 3.3 on my standalone centos 6.4 system. The 3.3 engine-setup apparently did NOT include the requisite iptables lines for port opening for the spice to function. I did a yum update for the ovirt-engine-setup to get the latest tool. Then I ran engine-setup to let the process upgrade as required. I added the missing ports from a second system I've not yet upgraded and all is well. Just though someone might want to look at a possible issue. -- -- James P.

Hello, I have a vm disk in glusterfs volume X. Now I have a replicated gluster volume Y. I would like to move the vm disk on it but if I go to "move" menu I cannot choose the target and I see a warning: "some disks cannot be moved". How can I move it? Thanks, Mario

[Users] Storage error after NFS reload
by Juan Pablo Lorier 07 Oct '13

07 Oct '13

Hi, I've made a change to the host where I run nfs for iso images and after reloading the nfs conf ovirt started to print to console and to log this every few seconds: <11>vdsm Storage.DomainMonitorThread ERROR Error while collecting domain 0d22a7d7-a7e0-4c17-b132-5764b7940a70 monitoring information#012Traceback (most recent call last):#012 File "/usr/share/vdsm/storage/domainMonitor.py", line 186, in _monitorDomain#012 self.domain.selftest()#012 File "/usr/share/vdsm/storage/sdc.py", line 49, in __getattr__#012 return getattr(self.getRealDomain(), attrName)#012 File "/usr/share/vdsm/storage/sdc.py", line 52, in getRealDomain#012 return self._cache._realProduce(self._sdUUID)#012 File "/usr/share/vdsm/storage/sdc.py", line 121, in _realProduce#012 domain = self._findDomain(sdUUID)#012 File "/usr/share/vdsm/storage/sdc.py", line 152, in _findDomain#012 raise se.StorageDomainDoesNotExist(sdUUID)#012StorageDomainDoesNotExist: Storage domain does not exist: (u'0d22a7d7-a7e0-4c17-b132-5764b7940a70',) Is there a way to stop this from happening without having to bring down the host?

[Users] oVirt Roadmap feature requests - Summary
by Itamar Heim 06 Oct '13

06 Oct '13

so, a lot of input post my question for 3.4 planning on "what do you want next"[1] I've just aggregated the replies here at this point for easier processing going forward: Infra - ability to give permissions to group of objects (namely, VMs) - support users/groups in oVirt DB as an authentication provider - support keystone as an authentication provider - kerberos login to webadmin/user portal - stateless host (pxe boot, no local disks) - detect updates and update host accordingly - embedded pxe/tftp boot server, setup to deploy the nodes - snmp & snmp trap monitoring Virt - template versions (ability to update template of a pool) - pci passthrough for devices like Telephone modem, PCI-express cards, Graphic cards - usbhost hook as supported feature (hardware license tokens) - ability to provide libvirt features directly[2] - dependencies between VMs (start db vm before webapp vm) - Allow to clone a VM without snapshot/template - Integrate v2v into engine - oVirt guest agent for Ubuntu/openSUSE/SLES/Debian - compatibility with OVF 2.0.1 - solaris as supported guest OS Network - private network between VMs - Network NAT for VMs (with buildin DHCP). - openvswitch support (in 3.3, via neutron?) - nic ordering Storage - import existing data domain - live merge (delete snapshot) - ability to resize a storage domain lun - multiple storage domains (local/gluster/FC) - ISO and export domains on FC/iSCSI - Upload ISOs within the GUI to ISO domain - Use an existing share for ISO domain - A backup and restore option - iSCSI EqualLogic SAN support or use standard iscsi tools/configuration - ATA over ethernet (AoE) as an optional storage transport - DR - DRBD, either with CLVM or perhaps GFS - live disk resize - disk ordering SLA - positive/negative affinity between group of VMs - power saving policy moving hosts to sleep - time based policy (SLA during the day, power saving at night) - collect and show power consumption of hosts - allow to give weights to prefer "faster" hosts to other hosts - application level HA (monitor the service inside the VM) Other - Zabbix monitoring [1] http://lists.ovirt.org/pipermail/users/2013-August/015807.html [2] http://lists.ovirt.org/pipermail/engine-devel/2013-August/005364.html

[Users] Gluster network info
by Gianluca Cecchi 06 Oct '13

06 Oct '13

Hello, I remember in the past that could be a problem to have high usage of ovirtmgmt network because engine sometimes detects hosts as unresponsive. And it should this the reason about bandwith limitation on vm migration, until dedicated network for it has been released. SO the question is : what about ovirtmgmt network for gluster replication when gluster domain is provided by ovirt nodes? I suppose it could be a problem too, couldn't it? In case I have a dedicated network for gluster for the nodes, how can i configure it? Can I configure in this case Gluster storage domain from ovirt engine or does it require to be on this network too? Thanks in advance for any suggestion Gianluca

[Users] internal networks in Ovirt
by subscription sites 06 Oct '13

06 Oct '13

Hi, I just installed ovirt 3.3 and got everything up and running with an ovirt node. However, I can't figure out how the networking works in ovirt. First of all, I'm looking for a feature like you have in virtualbox: configure bridged networks, internal networks and natted networks, how do you do each of these in ovirt? Also, I have only one physical nic and ovirtmgmt default network is already assigned to this nic. How can I attach other bridged networks to this same physical nic? Thanks for any help you can provide!

------=_Part_328376_145288176.1381065916525 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit Hi, We have been testing oVirt since 3.2.1, and have now upgraded the engine to 3.3 with the aim to use it in production for about 50 VMs currently running on 7 standalone CentOS 6.4 KVM hypervisors. We would prefer to use native GlusterFS integration, but I understand that CentOS 6.4 doesn't have the necessary library versions. Would it make sense to reinstall the hypervisors to oVirt nodes on Fedora19, or should we wait for CentOS 6.5? I'm not sure it feels very safe to use Fedora in production, even though it's the 'native' oVirt distribution..? I'm also not sure if Dell OpenManage is supported on Fedora, as this would be required for connecting the hypervisors/nodes into our common surveillance system. Maybe someone would say that we should use RHEV instead, but since we have managed with CentOS without vendor support on this particular service until now, I think we would be very comfortable with oVirt and the great support provided by the community. Anyone else having similar thoughts..?
