Re: Vcl and vmware HA
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 .

Then when VMware vMotions a machine, the VCL neither knows nor cares that this happened.

Re: openstack and VCL ?
Great. I'll create a jira issue on it to give it an initial home. You should see it come across the vcl-dev list shortly. Thanks again and looking forward to your presentation.

Would you be comfortable (if not now, soon) submitting the work under ASF for review by the VCL community?

We've also done a lot of work with OpenStack and our intent is for the module not just to work with Amazon EC2 but any cloud that implements the EC2 API, including OpenStack. Right now it's very much in a proof of concept state, but our intent is to open source it once some of the rough edges are smoothed over. We'll also be presenting a paper at the upcoming ICA CON 2012 on our work so far.

I think integrating openstack provisioning into the VCL framework would benefit VCL. It could also benefit openstack and their current users. From what I understand, Openstack has a large commercial base of users and could be a way to expose VCL to more commercial users. Unless I'm wrong, currently openstack doesn't provide a self-service interface for users to VDI or clusters, nor does it provide bare-metal loads. VCL with xCAT could provide that for that community in a short time-frame. Is there anyone interested in investigating and working on an openstack provisioning module ? I don't think it will take a huge amount of work, one would need to know openstack and how to add in a VCL provisioning module. I'd be willing to assist but would need someone to take the lead on it. Thoughts? I know this is a development question, but also felt this is big enough to include folks on the vcl-user list.

Re: ESXi 4.1 image for VCL reservation
Definitely doable. Also might be worth doing it within a ESXi server. Nested hypervisor - possibly a bit better control on which networks are visible. With the connection methods in the next release, you could define vsphere client as the connection method. Aaron P.

Re: ESXi 4.1 image for VCL reservation
There is definitely a performance penalty for running ESXi as a guest OS. I don't think the hardware virtualization features of the CPU can be passed on to an ESXi guest, which also means no 64-bit guests inside the ESXi guest.

Re: ESXi 4.1 image for VCL reservation
I'm not looking for nested hypervisors - this would work for someone who wants to play/study ESXi server. But even in this case VCL needs a module to handle ESXi reservation - this step would fail for nested esxi as well… How would I add/use/load a new pm module for ESXi reservation? I plan to use ESXi image along with a Windows sub-image with vSphere client, so ESXi server won't need public IP address in this case… I only need to address reservation steps (ie. get IP, add user, etc.) - xCAT/VCL already handles ESXi install process.

Re: ESXi 4.1 image for VCL reservation
Andy Could I extend existing ESXi.pm module at /usr/local/vcl/lib/VCL/Module/OS/Linux/ESXi.pm? Everyhing you described seems to be already in place - entry for esxi OS (OSid), module name/path. Thanks. -- Dmitri Chebotarov On Thursday, March 29, 2012 at 14:56 , Andy Kurth wrote: You could create an ESXi.pm OS module. It would inherit from Linux.pm since some of the Linux subroutines will work under ESXi. The module would reside at: lib/VCL/Module/OS/Linux/ESXi.pm Entries would have to be added to the module and OS tables in the database. Set your image.OSid value to the new value you enter in the OS table. Some of the subroutines in Linux.pm already work as you have noticed. I changed a few of them a while back to work with ESXi of them to which are called by the VMware.pm provisioning module when SSH is used to control the VM host. For the ones which don't work, you would define subroutines in ESXi.pm to override the ones in Linux.pm or OS.pm such as create_user. For the networking problems, you would probably define a post_load subroutine in ESXi.pm which performs operations necessary to configure the virtual switches appropriately such as running esxcfg-vswitch and esxcfg-vmknic. This would be very useful for us at NCSU. I would be happy to help get this added. -Andy On Thu, Mar 29, 2012 at 2:19 PM, Dmitri Chebotarov dcheb...@gmu.edu (mailto:dcheb...@gmu.edu) wrote: I'm not looking for nested hypervisors - this would work for someone who wants to play/study ESXi server.
