# qvm-ssh - Direct SSH access to the VM
|
|
#
|
|
# This script provides SSH access to the running VM:
|
|
# - Auto-starts VM if not running
|
|
# - Interactive shell by default (detects TTY)
|
|
# - Single command execution with -c flag
|
|
# - Passes through additional SSH arguments
|
|
# - Uses StrictHostKeyChecking=no for host key management
|
|

Usage: qvm ssh [OPTIONS] [SSH_ARGS...]
|
|
|
|
Open an SSH session to the VM or run a single command.
|
|
|
|
OPTIONS:
|
|
-c COMMAND Run a single command instead of interactive shell
|
|
-h, --help Show this help message
|
|
|
|
EXAMPLES:
|
|
qvm ssh # Open interactive shell
|
|
qvm ssh -c "ls -la" # Run single command
|
|
qvm ssh -c "pwd" -v # Run command with SSH verbose flag
|
|
|
|
NOTES:
|
|
- VM will auto-start if not running
|
|
- SSH connects as root@localhost
|
|
- Host key checking is disabled (VM overlay is ephemeral)
|
|
- Additional SSH arguments are passed through
