dom0: migrate from xend to libxl stack - qvm-core This is core part of migration. Things not migrated yet: - DispVM (qubes_restore needs to be almost rewritten) - VM xen config files should be fixed (use "script:" prefix in block device description, perhaps generate this files on VM start) Huge, slow xend not needed any more, now it conflicts with libxl

qmemman: offload some processing to meminfo-writer Make meminfo-writer compute used memory, and report to qmemman only if it has changed significantly enough. As it is written in C, its code is much faster that qmemman-server; also in the idle case, it saves on xenstore communication overhead. Allows to send updates up to 10 times per second, with CPU load on the VM below 0.1%.

qubes_dvm init.d script We want to set up a default dvm if needed at boot time; for this, the default netvm must have been already started. Therefore, we need a qubes_dvm script, that executes after qubes_netvm.
