[pve-devel] [PATCH qemu-server 1/3] add PVE::QemuServer::Cgroup

[Wolfgang Bumiller]

qemu doesn't actually have a limiting namespace subdirectory, so I'll
just replace this with:

    sub get_subdir {
        my ($self, $controller, $limiting) = @_;
        my $vmid = $self->{vmid};
        return "qemu.slice/$vmid.scope/";
    }
