Open Stack

Hi Bob,

Thanks for your early response, but I have no other options than running
Xen Server VMs on KVM, as this is requirement for my team.
We don't want to launch new VMs on KVM, instead our need is to migrate
running Xen Server VMs as it is on KVM.
For this I am trying to convert Xen Server image to qcow2 image and then
uploading on glance and then finally launching VMs using nova.
This way I will have my running Xen Server VMs migrated on KVM.
But I am not able to acheive this image conversion so far.
Any help would be highly appreciated.
