[pve-devel] training week: students feedback/requests

[aderumier@odiso.com]

Hi,
I just finish the last training week session,
here some students feedback/requesst:


- add support for vm offlline vm migration with local usb or pci
devices.
  1 student have same special device on multiple hosts, and want to be
able to offline move vm when it need to do maintenance.
  It's currently possible with HA anyway.

- allow vm migration with local storage cloud-init drive.
  Without need to replicate it, I think it could be pretty easy to
regenerate cloud-init drive on target host if same local storage name
exist on target.

- allow vm online vm migration for specific usb devices.
  Maybe a little bit more complex, user have special usb devices (googl
coral usb tensorflow accelerator) on multiple host.
  I think it could be possible to unplug device before migration, and
rattach it afte migration.  (The application running inside th vm is
able to handle this).
  So maybe adding an option on usb device like "allow migrate" could be
enough ?


- be able to move vms from a dead node.
  Currently the only was is to move manually the vms config files.
  Maybe adding a special wizard, only for root, with a lot of warning,
could be great. 


- Backups: add some kind of lock/queues when you are doing a single
schedule of "vzdump -all .."
Currently, it's launch vzdump on all nodes at the same time. 
If user have a lot of nodes, it can easily flood the backup storage, or
backup storage network.
it could be great to be able to define something like: "the backup
storage is able to handle X backups jobs in parallel"


- vm start order: be able to add vms dependencies, 
                  like a vm2 need to wait that vm1 is started (and if
guest agent is used, wait that agent is running, to be sure that vm1 is
fully booted)


Gui:

- Displaying nodes versions in the datacenter sumarry node list.

- In vms notes: if user add an http://... link, display it as link to
be clickable

- add saml authentification
