[Users] users quota and limit ips
by Andrej Bagon 23 Apr '13

23 Apr '13

Hi all, we are wondering how can we limit a user to use IPs we give him and not others. Best is understood from an example: - we give a user a quota (with x CPU, y memory and z disk space) - a user can create one VirtualMachine with all the resources, or more VirtualMachines with smaller resources. - we want to give a user a pool of IPs. He should not use other IPs. If he uses other IP it should not be routable. Is there a solution for this problem? Thank you. Best Regards, Andrej Bagon Arnes

In wui I can see it is down, but VMs are still reported to be running. (they dont, ofcourse..) I manualy rebooted that host and now it is up. But problem is, that I can not activate it in wui (still red) If I press "Confirm 'Host has been Rebooted'" it says: Manual fence did not revoke the selected SPM (node1.site.com) since the master storage domain was not active or could not use another host for the fence operation. If I try to put host in maitenance it says: Error while executing action: Cannot switch the following Hosts to Maintenance mode: node1.site.com. One or more running VMs are indicated as non-migratable. The non-migratable VMs are: vm2.site.com. I removed "HA mode" from vm2.site.com, but did not do the job. I can not even Power off running hosts. Is there any way what to do?

[Users] High Availability OVirt

Is there any way to create redundancy oVirt-engine? We install oVirt-engine in a machine, and what happens if that burning machine? Is there anything that can be done to remedy this? Att, -- “Encarada do ponto de vista da juventude, a vida parece um futuro indefinidamente longo, ao passo que, na velhice, ela parece um passado deveras curto. Assim, a vida no seu início se apresenta do mesmo modo que as coisas quando as olhamos através de um binóculo usado ao contrário; mas, ao seu final, ela se parece com as coisas tal qual são vistas quando o binóculo é usado de modo normal. Um homem precisa ter envelhecido e vivido bastante para perceber como a vida é curta”. (Poema de Arthur Schopenhauer)

[Users] Configure spice plugin for wan
by Gianluca Cecchi 22 Apr '13

22 Apr '13

I remember someone talking about an option of setting spice to operate over wan, in the sense that this way automatically it would disable effects in windows 7 VM, ecc... I don't remember if this is a VM parameter, hook or other... Or if this is an option available only in RHEV-M Any pointer? Thanks, Gianluca

Not getting very good quality playback when watching videos on a vm through spice console. It works, just very jittery. Have installed client tools and verified display driver is using the redhat driver. Any other ideas for improving video performance?

[Users] Templates and originating VM relationship
by Gianluca Cecchi 22 Apr '13

22 Apr '13

Hello, oVirt 3.2.1 on Fedora 18. I customize a CentOS 6.4 VM and when I comfortable I select "make template". I don't take any snapshot for the VM before this. I thought that VM would have been disappeared, transforming itself into a template, instead at the end I have both the template and the originating VM. Apparently with the same name for the disk and the same storage domain.... What is exactly the relationship between them? Can I safely remove the originating VM? I already tested making template and then deleting it and then being able to power on again VM and make a new template from the originating VM. The rhevm 3.1 admin manual is not so clear about this: it contains a note regarding " Take a snapshot of the virtual machine at this stage if you wish to use the virtual machine (as a virtual machine) after using it to create a template. " But if behavior of oVirt 3.2.1 has to be the same with it, this doesn't explain itself based on my experience.... Thanks in advance for any information Gianluca
