Re: libvirt/KVM
I don't have a libvirtlinux OS entry. I use vmwarelinux for KVM-based Linux images. This is what should be set when you capture a base image using vcld --setup. There is no difference among OS modules which point to the same Perl package path. The OS table is actually somewhat of a mess right now. Eventually it will be collapsed/normalized down so the is a single entry for all Linux images, otherwise we will end up with n-squared entries (OS's and provisioning types). Issue VCL-566 addresses this. -Andy On Wed, Jun 20, 2012 at 8:21 PM, Dmitri Chebotarov dcheb...@gmu.edu wrote: Andy Success! Thank you for your help. Correct, I'm working with KVM-based Linux image.
