[pve-devel] [PATCH container v2] api: record CT ID as used after a container is destroyed

[Aaron Lauterer]

This is missing a

use PVE::UsedVmidList;

at the top of the file. Otherwise running

pct destroy {vmid}

will result in the following error:

Undefined subroutine &PVE::UsedVmidList::add_vmid called at 
/usr/share/perl5/PVE/API2/LXC.pm line 799.

This doesn't seem to be necessary in the qemu-server repo, but I did not 
investigate further how pulling in dependencies works there.
