[pve-devel] [PATCH qemu-server, manager 0/12] bugzilla #4225 -- improve handling of unavailable ISOs

[Daniel Herzig <d.herzig@proxmox.com>]

Currently VMs refuse to to start if a configured isofile becomes unavailable,
be it a deleted file or an unavailable network storage.

This patch series introduces a new parameter in Drive.pm, called 'required'.
Depending on whether this parameter is set or not, the situation will be handled
differently.

If the parameter is set to 0, the configuration will temporarily changed to use
'none' as file for the cd drive, which allows qemu to start up the machine.
The configuration is not changed in this process to avoid unexpected behaviour.
Instead a log_warn will be issued.

For transition reasons an unset parameter acts like 'required=1'. In this case
the startup process will die earlier than currently, if the file is missing or
the underlying storage not available.

If however a new VM is created from the WebGUI, the corresponding added checkbox
is not checked by default, and the resulting 'required=0' will be written to
the configuration.

To allow for proper testing and building some additions and minor changes
where made to to the testing framework as well.

Not exactly part of #4225, but related to it, this patch series adds an 'Eject'
button to the hardwareview in the WebGUI, which can be used as a convenience
shortcut to manually editing the missing ISO file to 'Do not use any media'.
