- host_is_up returned the exception object for a down host, which is
truthy: check_user_quota then connected to it and failed, so a user
with a VM on a down host could not open its page, clone or resize,
and migrate_instance's "target is down" check never fired. It returns
True or False now, closes its socket, and accepts IPv6 and host:port.
- The connection manager no longer holds its global lock while a new
connection is opened, so one slow host does not delay new connections
to the others.
Bounding the connection time itself (including SSH aliases and jump
hosts) is left for a separate change.
Clone:
- only shut-off VMs are cloned, as the UI already required: a running
guest keeps writing while its disks are copied; the definition comes
from the persistent XML;
- MAC addresses and disk destinations are checked before anything is
allocated;
- every volume the clone creates (NVRAM and disks) is tracked; if a
later copy or the definition fails, only those are deleted, and any
that cannot be deleted are named in the error. Before, a failed clone
left its earlier copies behind.
libvirtError(msg) reports the thread's last libvirt error instead of
msg when there is one, so WebVirtCloud's own errors could show an
earlier, unrelated failure. util.OperationError, a libvirtError
subclass that keeps its message, replaces those raises in vrtManager,
instances and nwfilters; 'except libvirtError' still catches it.
SPICE was removed earlier; its leftovers and the console type choice go
too:
- the console settings form, update_console and the backend no longer
offer or change the type; an invalid console form now shows its
errors instead of being ignored;
- the create form, the API serializer and create_instance no longer take
a graphics type, new VMs get VNC; get_graphics_types and the graphics
entries of the domain capabilities are gone;
- migration appsettings.0013 deletes QEMU_CONSOLE_DEFAULT_TYPE;
- a VM defined elsewhere with another graphics type gets "Console type
... is not supported".
The locale catalogs still reference the deleted SPICE templates in
source comments; regenerating them is left to the translation work.
move wvmCreate.get_cache_modes() to wvmConnect
add wvmConnect.get_busses(), wvmConnect.get_image_formats(), used in forms
add corresponding default values to settings (INSTANCE_VOLUME_DEFAULT_FORMAT INSTANCE_VOLUME_DEFAULT_BUS INSTANCE_VOLUME_DEFAULT_CACHE)
