[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

On RHEV 3.1,after a disk was successfully live migrated from one storage domain to another,I noticed that on the Admin Portal,it was being reported as a Thin allocated disk.It was originally a preallocated disk.Is that expected? Thanks, Marc
