Vcl and vmware HA
Hello, Is anybody dealing with VCL and ESX Vmotion underneath? Has anybody done any research or work on this? Anu Chirinos UTS - Operations and Enterprise Systems Florida International University Office (305) 348-0275 Cell (786) 712-9025
Re: Vcl and vmware HA
Yes, we are using vMotion with our ESX hosts. It involved writing a custom provisioning module which is slated to be part of the next VCL release. The short version is that all of the ESX hosts are put into a single vCenter host, and the VCL communicates only with that single host (even though there may be many physical hosts). Then when VMware vMotions a machine, the VCL neither knows nor cares that this happened.

Re: openstack and VCL ?
Hi Aaron, One of the things we're working on at Cybera is an EC2 provisioning module. 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: Vcl and vmware HA
Hi Anu, Yes it will likely be mid-end of April now for the 2.3 release. End of March timeline I proposed in Jan/Feb was too optimistic on my part.

Wndows pagefile.sys settings
Hi, All I'm using Windows 7 Ent image with VCL/xCAT on a blade with 48GB of memory. Before capturing the image I set page file to 2GB, once capture is done, the new reservation ends up with 48GB page file. This leave little space left to install new applications. I found that Windows.pm calls disable_pagefile() on line 474 during image capture. Would it be OK to disable this function? Thank you. -- Dmitri Chebotarov Virtual Computing Lab Systems Engineer, TSD - Ent Servers Messaging 223 Aquia Building, Ffx, MSN: 1B5 Phone: (703) 993-6175 Fax: (703) 993-3404

Re: Wndows pagefile.sys settings
James Yes, I have changed the setting for pagefile. But it resets to default after I capture image and make reservation. I've also commented disable_pagefile() in Windows.pm (and restarted vcld), but it doesn't help. New image still has default pagefile setting. Is there another place in the code where I could stop VCL from changing pagefile settings? Thanks. -- Dmitri Chebotarov Virtual Computing Lab Systems Engineer, TSD - Ent Servers Messaging 223 Aquia Building, Ffx, MSN: 1B5 Phone: (703) 993-6175 Fax: (703) 993-3404 On Wednesday, March 28, 2012 at 16:19 , James O'Dell wrote: -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Have you tried disabling/reducing the page file before making the image?
