Subject Re: Vcl and vmware HA
Date Thu, 29 Mar 2012 13:27:03 GMT
Not is this upcoming release. With VMware HA, it's easily handled by
vcenter if you have the correct licenses...

With the libvirt module - this release is going to support kvm.
Libvirt also supports vmware, but that would need to be added in later
if necessary. The current work that Aaron Coburn and Andy Kurth have
done with the VMWare prov module are fairly robust, so I'm not sure if
the libvirt-vmware part is needed.

On the kvm side, there would need to be HA logic built into the
libvirt-kvm module. Or there would need to be a work done to talk to
RHEV - Red Hat's equivalent to vcenter, but for kvm hypervisors.

Others may also have other thoughts on this. It's ideal (probably
needed) as we get into more server based provisioning to have HA
functionality for the kvm, it would be good to start designing this
part out and possibly target a later release 2.3.x .
