kcli VM Operations

VM Lifecycle Commands

Create VM

Copy# From image
kcli create vm -i fedora40 myvm

# With parameters

# From profile
kcli create vm -p myprofile myvm

List VMs

Copykcli list vm                    # All VMs

kcli list vm -o json            # JSON output

VM Info

Copykcli info vm myvm               # Full info

kcli ssh -u root myvm           # SSH as specific user
kcli ssh -l myvm                # List SSH command only

Console Access

Copykcli console myvm               # Graphical console (VNC/SPICE)

Disk Operations

Copy# Add disk
kcli create disk -s 20 -p default myvm  # 20GB disk

# List disks
kcli list disk

NIC Operations

Copy# Add NIC
kcli create nic -n mynetwork myvm

# Delete NIC

# Update NIC
kcli update nic -n newnetwork myvm --index 0

Snapshots

# List snapshots
kcli list snapshot myvm

# Revert to snapshot
kcli revert snapshot myvm mysnapshot

# Delete snapshot
kcli delete snapshot myvm mysnapshot

VM Configuration

Configuration Hierarchy

Parameters are resolved in order (later overrides earlier):

1. kvirt/defaults.py - Built-in defaults
2. ~/.kcli/config.yml default section
3. Provider-specific section in config.yml
4. Profile definition (~/.kcli/profiles.yml)
5. Plan file parameters
6. Command-line -P overrides

Troubleshooting

VM Won't Start

Copykcli -d start vm myvm              # Debug output
sudo virsh list --all               # Check libvirt state
sudo virsh start myvm               # Try direct start

No IP Address

Copy# Check DHCP is enabled on network
kcli info network default

# Check cloud-init completed
kcli ssh myvm
cat /var/log/cloud-init.log

SSH Connection Issues

Copy# Get SSH command details
kcli ssh -l myvm

# Check VM has IP
kcli info vm myvm -f ip

# Try direct SSH
ssh -i ~/.kcli/id_rsa user@<ip>
