A: Users@ovirt.org Users@ovirt.org Hello, I read the following page : http://www.ovirt.org/OVirt_Guest_Agent_For_Windows and applied it on a server, and it ran very well. I obtained the two executables, copied them into program files according to the doc, along with the .ini as stated here : https://www.mail-archive.com/users@ovirt.org/msg18561.html - the -install, the start, and the enabling went fine - rebooting the server runs OK too, and the agent is seen by oVirt What I don't understand is the following sentence of https://github.com/oVirt/ovirt-guest-agent/blob/master/ovirt-guest-agent/README-windows.txt Optionally install py2exe if you want to build an executable file which doesn't require Python installation for running As I don't know python at all, I thought this was building some sort of self-executable binary that I could copy-paste into another VM, and do the same install/enable/run. And WITHOUT installing any Python environnement. I'm sorry for such a weak question, but if this is not the case, does that mean I have to install a Pyhton env on each of my windows VMs? BTW, I tried to copy-paste the programfiles/guestagent... into another server, and when running the install, it gives a message [in french, :( ] L'application n'a pas pu démarrer car sa configuration côte-à-côte est incorrecte. That could be translated by : The application could not start because its side-by-side (?) config is incorrect. PS : Time is not anymore at launching windows_vs_linux war, but I just installed the guest agent on 17 _linux_ VMs in 3 minutes... Haven´t tried what Lev said, using the new ISO, but as the person who wrote the wiki page, yes, you need to install _either_ python or, as Lev said, the VC runtime for the exe's to work on each guest. In practice though you create a template with this installed _one_ time, then spawn the rest of your VM's from that. But e.g. converting lots of VM's that came from another virtualization platform you´d need the VC runtime (or python) and exe's installed in each VM for the guest agent to work. Do you know there´s a third-party package manager for windows called Chocolatey, kind of like yum for Windows? That together with Puppet (or plain-old SCCM) makes Windows management lots easier. /K -- Med Vänliga Hälsningar --- Karli Sjöberg Swedish University of Agricultural Sciences Box 7079 (Visiting Address Kronåsvägen 8) S-750 07 Uppsala, Sweden Phone: +46-(0)18-67 15 66 karli.sjob...@slu.se ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Re: [ovirt-users] How to stick VM to hosts?

When using iSCSI, they are not shared. You have to make sure your storage infrastructure allows multiple connection to the iscsi LUN. But there is nothing to do about sharing on the block level. When migrating data in iSCSI environement, according to what I've witnessed, blocks are dd'ed (so this takes time) from the SD source to target. I guess that's where glusterfs adds some benefit.

I don't want to add access to the whole portal server directly. Is it possible? Thanks in advance, Tibor Why not simply put a proxy for your external users that points to the URL of the user portal? That should be relatively easy with Apace and mod_proxy, or your proxy of choice. I am assuming you are simply trying to prevent users from changing the URL and seeing the webadmin URL, or the welcome page. ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
Re: [ovirt-users] shared storage with iscsi
Thanks Gianluca,it says only NFS is supported as export domain.I believe export domain is the one i am currently using for live migrating vms across hosts.So iscsi is not supported,please correct me if i am wrong.Thanks for your help On Thu, Dec 4, 2014 at 9:00 PM, Gianluca Cecchi gianluca.cec...@gmail.com wrote: On Thu, Dec 4, 2014 at 4:23 PM, mad Engineer themadengin...@gmail.com wrote: Thanks Maor,in non ovirt kvm setup i use GFS2 to make the block device shareable across multiple hosts.Could you tell me how is it achieved in ovirt.

Then indeed, you're right, iSCSI is not supported for export domains. In our case, we are providing some iSCSI LUNs as export domains via the managers which are serving them as NFS shares. Performance is OK.

I believe export domain is the one i am currently using for live migrating vms across hosts. That's not true. You're not using the Export Domain to support live migrations. Your VMs are running in a regular Storage Domain (not Export Domain), probably NFS, and it could be iscsi. So iscsi is not supported,please correct me if i am wrong.Thanks for your help On Thu, Dec 4, 2014 at 9:00 PM, Gianluca Cecchi gianluca.cec...@gmail.com wrote: On Thu, Dec 4, 2014 at 4:23 PM, mad Engineer themadengin...@gmail.com wrote: Thanks Maor,in non ovirt kvm setup i use GFS2 to make the block device shareable across multiple hosts.Could you tell me how is it achieved in ovirt.

Re: [ovirt-users] shared storage with iscsi
sorry i am wrong its the data domain that stores virtual disk images,I have no idea how ovirt shares block device across hosts.Looks like i need to try that for understanding how its implemented.In case of vmware they uses vmfs file system for sharing block device among hosts.I currently have no issues with my NFS shared storage so dont have any plan to use iscsi,but just curious how the implementation is.In my existing non ovirt environment,SAN block devices is exported and its shared using GFS.Is ovirt using any simillar method to achieve shared block device.

The idea is pretty simple 1. format the shared block storage with LVM 2. Every VM disk image is an LV 3. manage host access to separate LVs using simple lvchange. Of course there's much more to the way this is implemented, but very simply - no two hosts have write access to the same LV, unless it is specified as a shared disk, so no clustered FS is needed, no scsi reservations are needed and this concept scales, unlike vmfs, gfs, and other such systems.

It's not shared considering the lowest level. Each disk corresponds to a LVM logical volume, which is activated only on the specific hypervisor running the VM. Others hypervisors cannot access the logical volume while the VM is not running on it (except for shared disks). To activate the logical volume (in order to run the VM), hypervisor runs a lvchange -ay vol_group/logical_vol In my existing non ovirt environment,SAN block devices is exported and its shared using GFS.Is ovirt using any simillar method to achieve shared block device.
