[Users] Define vlan (pvid and/or trunk) per vNic ? - openvswitch integration
Hello, I'm writing to the ml to know something about ovirt : Is there any possibilité to define a vlan per vNic (pvid and/or trunk) , for each vnic of VM ? I'm working with openvswitch and i can define this. Well, for us, it's the absolute needed (and killing) feature to define well known n-tiers architecture in a virtual world (web fronted, BDD, load-balancer and so on). I'm interesting by oVirt because it seems to be an integrated web interface. Thank you in advance !

We suspect that is much more resource intensive than it is with VServer. Whatever model we choose, we then need a transport protocol and, as SPICE is refined especially in its handling of WAN video, we are quite interested in using it rather than RDP for transport.

Re: [Users] Bangalore Workshop Talk Submissions (was: Re: Speakers Needed: Upcoming Workshops)
Hello All, I would like to submit a proposal in the Bangalore Workshop along with my colleague Surya Prabhakar. Here is the Abstract --- Base Board Management Controller(BMC) that is present on each of the servers has wealth of hardware information. Apart from performing the usual fencing tasks, BMC can play a more critical role in a visualization environment. Effective usage of BMC will allow virtualization solution to manage the hosts more efficiently. Current oVirt-Engine`s scheduling policy overlooks the real status of a server which can only be given by the onboard BMC. Consider a situation wherein a thermal sensor on a Host has crossed its threshold limits. In the current oVirt setup, the engine would continue to use this tainted Host either by scheduling more VMs or continue hosting the existing VMs. This Host at some point of time is set to fail. Is there a better way of handling such situations or events in oVirt ? The objective of the talk is to highlight the importance of having BMC as part of the oVirt stack and also touch upon the different options that are available to integrate BMC awareness in an oVirt Stack. And here is something about me and Surya - Surya Prabhakar: He has close to 10 years of experience in embedded and Linux development. Currently working as Senior Software development engineer in Dell India RD centre. His work majorly focuses on making the Dell servers working best with various Linux distros out of the box. He has presented papers in in forums like Opensource India ( OSI tech days ) and conducted workshops in universities on cloud and virtualization. Working with openstack cloud software is his passion.

Re: [Users] vdsm/engine do not like Infiniband
This is a test setup so no worries about future breakage via upgrade.

I then restore the altered database and go about business as usual.
