SSH access
What to check when you can't SSH into a VM.
- SSH connection checklist: 6 steps covering public IP, firewall (port 22), the sshd service, key permissions, and
ssh -vvvdebugging - Connection closed by … port … error: wait 1–2 minutes after creation, confirm boot via the web console
- Allowing SSH from specific IPs only: firewall ACCEPT/DROP ordering
GPU / drivers
GPU detection and CUDA-related issues.
- nvidia-smi isn't working: recover the driver by rebuilding DKMS after a kernel update
- Driver/Library version mismatch error: module versions drift apart after manually changing the driver
- PyTorch can't find CUDA: PyTorch ↔ CUDA version mismatch,
CUDA Error 802 (system not yet initialized), automating setup with on_init_script
General VM questions
Frequent questions about creating and operating VMs.
- My VM won't create: quota and capacity diagnostics
- I'm still being charged even though I stopped the VM: storage and public IPs are billed separately
- Using NVMe cache storage
- The web console won't open
- Login fails after reusing an existing block storage: log in with the original VM's username and password
- Networking is broken after reusing an existing block storage: clean up old NIC settings with
cloud-init clean - Diagnostic state shows Unhealthy / Unknown: check
eci-guest-agentand GPU detection
Billing / cost
When the bill doesn't match your expectation.
- When does billing start?
- The bill is higher than expected: common leaks
- A spot VM was reclaimed — am I still being charged?
- Cost-saving tips
Storage
Common issues with block storage, object storage, and PFS.
- Can I grow block storage?: resize procedure
- I can't create more block storage because of the quota: check resource usage and request an increase
- rclone won't connect to object storage
- df -h shows odd capacity after mounting PFS
- PFS won't mount after rebooting the VM: reinstall the vastnfs driver after a kernel change
- Does restoring from a snapshot overwrite my existing data?
Deleting resources
What to check when a resource will not delete, or the delete button will not respond.
- A resource will not delete: reading the attached resources the dialog lists
- When does "Detach and delete" appear?: public IP ↔ interface, disk ↔ virtual machine
- The delete button is disabled: child resources to clear first
- Can I delete a disk attached to a running virtual machine?: stop it first
- Why do I have to type the name to delete?
