Latest QEMU versions support various migration capabilities. Each can be enabled/disabled with 'migrate_set_capability' monitor command. Version 1.7.0 defines x-rdma-pin-all, auto-converge, zero-blocks, and xbzrle migration capabilities. Since migration capabilities are more than one, and because hvparams accept only strings/integers and not dicts we decide to provide the capabilities that should be on via a ":" separated string. In other words one can use the following to enable xbzrle and auto-converge: -H kvm:migration_caps=xbzrle:auto-converge IMPORTANT: xbzrle may result to BSOD for instances running Windows 2008r8 on drbd. Update man page of gnt-instance to include the new hvparam.
