Hello, we are using Proxmox 5.4 : pve-manager/5.4-10/9603c337 (running kernel: 4.15.18-12-pve) We want to install Kemp Virtual LoadMaster (VLM) from Linux disk image available on the Kemp Website. We have tried to install it from the "Create CT" fonctionnality by uploading the tar.gz file into the /var/lib/vz/template/cache folder. The uploaded template is available in the GUI of proxmox but when we try to create the CT, the following error occured : Task Create CT Using default stripesize 64.00 KiB. Logical volume "vm-4220-disk-0" created. mke2fs 1.43.4 (31-Jan-2017) Discarding device blocks: 4096/8388608 done Creating filesystem with 8388608 4k blocks and 2097152 inodes Filesystem UUID: c41d9b08-b2f4-41b3-932d-9451c74471d3 Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208, 4096000, 7962624 Allocating group tables: 0/256 done Writing inode tables: 0/256 done Creating journal (65536 blocks): done Multiple mount protection is enabled with update interval 5 seconds.
