[Users] CT live migration stages duration

Hello all! I'd like to do some research on how long each stage of OpenVZ CT live migration takes. I wonder if there is any single source of such information with particular timestamps? So far as I understood "-v" flag in vzmigrate command can't help me much with what I'd like to achieve. "-t"

Re: [Users] libvirt

We arealso interested in using OpenVZ via libvirt. Together with our colleagues from another organization we are using local private cloud infrastructures based on OpenNebula. OpenNebula doesn't have yet native support of OpenVZ. So we had to develop own OpenVZ driver for OpenNebula and update
