| Issue | Possible Solution |
|-------|------------------|
| Version mismatch | Ensure client version matches the repack’s required version (check repack docs). |
| Database connection failed | Verify MySQL is running and credentials in config files are correct. |
| Server won’t start | Install missing Visual C++ runtimes; run executables as Administrator. |
| Character stuck at login | Check TB_USER table in database for corrupted data; delete and recreate. |
| Lag or disconnects | Open required ports (e.g., 15001, 15100) in Windows Firewall. |
KT’s SO might require specialized virtual drivers (e.g., VirtIO for high-performance networking or custom paravirtualized SCSI controllers). A repack allows you to integrate these drivers post-OS installation.
With KT aggressively moving toward cloud-native network functions (CNFs) based on Kubernetes, the concept of repacking full VMs may shift to repacking Helm charts and container images. However, legacy VNFs will persist for years, making the virtual KT SO repack skill valuable. Additionally, KT’s internal orchestration layers (e.g., T-MANO) still rely heavily on OVF compliance. virtual kt so repack
Include timestamps and slide counts to keep sessions focused.
| Problem | Likely Cause | Solution |
|--------|--------------|----------|
| KT SO rejects repacked OVA | Mismatched OVF disk capacity | Recalculate capacity and update ovf:size attribute |
| VM boots but agent fails | SELinux context lost during repack | Use virt-customize --selinux-relabel |
| Network interfaces reorder | MAC address changes | Persist MAC-to-interface mapping via /etc/udev/rules.d/70-persistent-net.rules |
| Image becomes larger after repack | Not using sparsify | Always run virt-sparsify before final conversion | | Issue | Possible Solution | |-------|------------------| |
If KT SO uses cloud-init, inject a user-data script:
virt-customize -a disk.qcow2 --copy-in user-data:/var/lib/cloud/seed/nocloud/
Then repack as above.
The final step of the Virtual KT SO Repack is iteration.
