Thanks Wido!
Right now I can think in creating bash scripting like this to run specific
commands on VMs
#!/bin/bash
VM_NAME="i-xx-xxx-VM"
# Timeout
TIMEOUT=5
# JSON Command
COMMAND_JSON=$(cat <<EOF
{
"execute": "guest-exec",
"arguments": {
"path": "/tmp/echo_hello.sh",
"capture-output": true
}
}
EOF
)
result=$(virsh qemu-agent-command "$VM_NAME" "$COMMAND_JSON" --timeout $TIMEOUT)
echo "Result: $result"
But would be nice to have a module on Cloudstack like user-data but to send ops
commands on the running command, I will create the PR then.
Regards,
Ricardo Pertuz
