[pve-devel] vm stop tasks hanging

>>Or one target (possible several luns) per VM?

mmm,I think it's can be more difficult, but with iscsi we can share disk between vm.(It's possible now with proxmox).
Maybe some other things like disk hotplug/unplug will be more difficult if we need to login/logout target.

The model 1target-1lun is used by openstack for nexenta and other san applicances, I think esx/xenserver also doing it

no problem ;) take your time...

I'll make some tests with lvm, to see how I can speed the scan with many disks.

Alexandre

Or one target (possible several luns) per VM? 

Sorry, I am still not ready with the plugin code - will try next week.
