Red Hat Virtualization Architecture
Hello,
This discussion is created as a follow up to the session I gave in Red Hat summit 2012 on RHEV architecture.
In the session I covered the various RHEV components and the interaction between them.
I invite you to use this platform for asking questions, making comments and giving feedback.

Hi Livnat
Another question for you....
In the latest release of 3.0 I noticed that support for hyperthreaded CPU's has been dropped from the hypervisor.
I understand that this was due to some issues with scheduling vCPU's on physical hyperthreaded CPU's.
Do you have any further information regarding this ?
(I expect with will also effect regular KVM servers and clusters with HT enabled hardware?)
Hi Livnat
Yep, that's exactly what I was refering to. Thanks very much for the additional insight.
I am one of those that was "..mislead by seeing a large number of cores.....". In hindsight, I can now see that HT makes no odds to the performance of the hypervisor or more importantly availability of CPU cycles to the resident VM's.
It is indeed jolly annoying that I an unable to view these "private" bugzilla's, even ones that result from my own RFE's ! But I'll take that battle elsewhere.....
Thanks again.
Hi Livnat
That's great news !
The fileinject hook looks useful (http://gerrit.ovirt.org/gitweb?p=vdsm.git;a=tree;f=vdsm_hooks).
Thanks for that.
