[ovirt-users] change disk size using a thin provision based template
Hello, I am making some tests and this time I want to reduce the disk size before create a new vm (in the new vm window ) test: 1) click on new VM 2) select template (centos6.5 , 6GB, 500GB HD , 2 cores) 3) resource allocation : select preallocated disk 4) change disk size it is not possible ! Why I can not change disk size ? I know it is based on template who had already defined (500GB), but this template in fact has only 4GB of actual size in thin provisioning allocation policy . thanks tamer ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
[ovirt-users] how to remove VM and Hosts ?
hello what is the correct procedure to remove VMs and Hosts? I know the right way is to remove VMs first then remove your Host, but I generate 20 VMs, just for testing, and I want to remove either the host who hosts this VMs Environment: 3 servers: srv-01 = engine , vdsm srv-02 = vdsm , spm, lots of VMs srv-03 = vdsm , lots of VMs I removed 2 hosts of my ovirt-engine steps: 1) select host and put on maintenance 2) stop all VMs 3) remove host But in VM tab I can see all VMs and can not remove . steps 1) select VM and click on remove Are you sure you want to remove the following items? - pvm0203-2 Remove Disk(s) 2) click ok Operation Canceled Error while executing action: pvm0203-2: Cannot remove VM.

Re: [ovirt-users] how to remove VM and Hosts ?
I reinstalled the hosts step: 1) create new host I selected srv-02 2) host created 1) create new host I selected srv-03 2) host created and noticed two things : 1) I tried now, to remove the remaining VMs , but the error was the same : Cannot remove VM. VM is attached to a VM-Pool. 2) I can run theses VMs . That is, I can remove the host and reinsert again without VM problems. 2.1) And another detail: these VMs are thin/dependent. All others VMs that I was able to remove was the type clone/independent. What happens with this thin type provisioning?

Re: [ovirt-users] how to remove VM and Hosts ?
Problem solved: The VMs are related to POOL To remove these VMs 1) on tab POOLS : detach each VM from pool 2) remove pool (when I choose to detach all VMs from the pool this will remove the pool itself) When I do this , on the VM tab the icons of VMs changes from Pool Icon to Server Icon Then, on VM tab I select desired VM and click on remove. Now it works. finally: all VMs removed. now I can remove the Hosts On Tue, May 6, 2014 at 2:59 PM, Tamer Lima tamer.amer...@gmail.com wrote: I reinstalled the hosts step: 1) create new host I selected srv-02 2) host created 1) create new host I selected srv-03 2) host created and noticed two things : 1) I tried now, to remove the remaining VMs , but the error was the same : Cannot remove VM.

Hi , Yair yes, I dont want to re-install ovirt I'm not sure if allInone could be fix this problem. allinone install vdsm on the same ovirt-engine host. Well, I already have this : ovirt-engine, vdsm on the same host: srv-0202 My storage domains(data and iso) are hosted on srv-0202 I believe my solution is create one engine per server.

Re: [ovirt-users] compatibility relationship between datacenter, ovirt and cluster
ok, Itamar, thanks. now I can understand how the things work. but I have a question based on the fact that I have ovirt-engine on version 3.4 and DC and Cluster both are configured on version 3.3 : - This means that I have available features on version 3.4 , but these features just will work when I update DC and Cluster to version 3.4 ? (this is what I understand, following Dafna Ron response) so, to really obtain the benefits of the new version (3.4) I need to run the commands (yum update ovirt-engine-setup, engine-setup) and also increase the version of compatibility within the datacenter, cluster and host to the version 3.4 - and what I have if only update ovirt-engine to version 3.4 and not update dc, cluster neither hosts. I realized changes on ovirt web admin interface, improvements on icons and maybe new fields.

[ovirt-users] necessity to run yum update ovirt-engine-setup to update ovirt 3.4
hello,
upgrade from ovirt 3.3 to 3.4
following the steps on ovirt.org/OVirt_3.4_Release_Notes
I tried update from yum, without success
yum update {ovirt-engine-setup, ovirt-engine , ovirt-release and
ovirt-release-el6 }
Then I tried the following command and it worked fine: engine-setup
Now my ovirt works fine, my cluster is running virtual machines on
compatibility mode 3.3 although ovirt is now 3.4
Then I ask : What is the necessity to execute *yum update
ovirt-engine-setup* if when I execute only *engine-setup* this script
search for updates ?
Failed command list execution
For each command *yum update {ovirt-engine-setup, ovirt-engine ,
ovirt-release and ovirt-release-el6 }* the result was the same :
