[pve-devel] [PATCH v2 qemu-server++ 0/15] remote migration

["Fabian Grünbichler" <f.gruenbichler@proxmox.com>]

this series adds remote migration for VMs.

both live and offline migration including NBD and storage-migrated disks
should work.

besides lots of rebases, implemented todos and fixed issues the main
difference to the previous RFC is that we no longer define remote
entries in a config file, but just expect the caller/client to give us
all the required information to connect to the remote cluster.

new in v2: dropped parts already applied, incorporated Fabian's and
Dominik's feedback (thanks!)

overview over affected repos and changes, see individual patches for
more details.

proxmox-websocket-tunnel:

new tunnel helper tool for forwarding commands and data over websocket
connections, required by qemu-server on source side

pve-access-control:

new ticket type, required by qemu-server on target side

pve-guest-common:

handle remote migration (no SSH) in AbstractMigrate,
required by qemu-server

pve-storage:

extend 'pvesm import' to allow import from UNIX socket, required on
target node by qemu-server

qemu-server:

some refactoring, new mtunnel endpoints, new remote_migration endpoints
TODO: handle pending changes and snapshots
TODO: proper CLI for remote migration
potential TODO: precond endpoint?

pve-http-server:

fix for handling unflushed proxy streams

as usual, some of the patches are best viewed with '-w', especially in
qemu-server..

required dependencies are noted, qemu-server also requires a build-dep
on patched pve-common since the required options/formats would be
missing otherwise..
