[Users] VDSM and RHEL problem
by Jonathan Cox 24 Jul '12

24 Jul '12

Hello, I am running Ovirt 3.1 and everything was running well but then I decided to upgrade to a system with more memory for the engine and now the VDSM version dropped to 3.1 and the RHEL is complaining that there is no compatible pc. This wasnt a problem before and I tried to go back to the old system but now both of them are giving the same error. Anyone have any ideas what I should be looking to fix here? I am not sure if the 2 problems are related, I am running CentOS 6.3, Ovirt 3.1 and using the dreyou builds. Thanks -- Jonathan H Cox

[Users] oVirt and AWS
by Jamie Pow 24 Jul '12

Hi Guys, Hope you are all well. I am currently putting together a test rig to use this software in my company for VM maanagement. I am using AWS to host this at the moment. I am having trouble adding a new host. When I enter the details and click ok I recieved an error telling me I cannot add host. Failed to create SSH...... If anybody has managed to succesfully configure this on AWS and/or provide some pointers would be much appreciated. Many thanks folks! Jamie

Re: [Users] "Error: Cannot attach Storage. Storage Domain doesn't exist."
by Johan Kragsterman 21 Jul '12

Hmm, I'm going to do some research here... Story is that the first LUN I attached was 30 Gb. Since the LUN's are attached by the same Fc HBA and same port, it is most likely that they get the same device name, even if I change the LUN behind, in the SAN controller. Do someone know something about this? Is it likely that the HV system save some LUN/device information in it's system LUN? So that it reports the same size of the LUN that it was originally? I am going to remove the LUN again, and take away the LUN mapping, so the HV can't see it. Then I will make a new LUN of different size again, and check if it has the same device name, and also check what size it reports. I would appreciate if someone with deeper knowledge than me about these things could shed some light here...
