Charles, I'm not sure why you want to do that? I think I may have a way to get it work with
Ubuntu, just that it failed for a number of reasons and worked perfectly with Wheezy. My view
is that Debian has higher a security and test standards for their releases. (note: systemvms
are also made out of debian), Wheezy should be released around February 2013 (the freeze was
around June-July 2012, if I recall correctly), like we had the previous releases; Lenny's
February 2009 and Squeeze's February 2011.

Does it matter what flavour of Linux runs as dom0, as long as the xen host works fine and
networking is not an issue. Marcus and I talked about kvm during ccc12, I've haven't tried
it myself but it's was claimed that it works; yes you can run a devcloud appliance on a KVM
host (instead of on VirtualBox), run devcloud (a wheezy based base with xen server) directly
over kvm. (Note kvm won't run on virtualbox (no pv, only hvm), what I'm suggesting is that
you run KVM over baremetal, a intel-vt/amd-v processor.)

Regards.

Hi Edison, Anthony, Rohit,

The new DevCloud2 image (http://rohityadav.in/logs/devcloud/) runs on
Debian - Wheezy (
http://people.apache.org/~bhaisaab/cloudstack/devcloud/devcloud2.ova) and
not anymore like DevCloud1 (http://wiki.cloudstack.org/display/COMM/DevCloud)
on Ubuntu (http://download.cloud.com/templates/devcloud/DevCloud.ova).

If I understand correctly, you would recommend that we create a new image
running in virtualbox using CentOS ? And with qemu or qemu + KVM ?

Remark : In my case, the guest OS is MacOs 10.7.5 and DevCloud2 (= Debian
Wheezy + Xen4.1) runs in VirtulBox (4.2.4)

Regards,

Charles
