Virtiofsd, Problems with qemu VM launch script

 If you're encountering problems with your QEMU VM launch script that uses `virtiofsd`, it's essential to diagnose and troubleshoot the issues. To help you effectively, it would be helpful to know the specific problem you are facing, any error messages or behaviors you're experiencing, and details about your launch script. Here are some common troubleshooting steps and considerations:


1. **Check for Dependencies**: Ensure that you have all the necessary dependencies installed, including QEMU and `virtiofsd`.


2. **Verify Path Configuration**: Make sure you have the correct paths to your guest filesystem and shared folders specified in your `virtiofsd` and QEMU command lines. Incorrect paths can cause issues.


3. **Check Permissions**: Ensure that your user has the necessary permissions to access the shared folders and the required filesystems. You may need to use `sudo` or adjust file permissions if necessary.


4. **Use Correct Options**: Double-check the options you are passing to `virtiofsd` and QEMU. Verify that you are specifying the correct mount points, security options, and other relevant flags.


5. **Debugging Output**: If you're experiencing errors or issues, consider adding debug output to your script to help pinpoint the problem. For example, you can use `echo` or `log` statements to log information at different stages of your script's execution.


6. **Check Kernel Support**: Ensure that your host and guest kernels support Virtio-FS. Virtio-FS requires kernel support, so both your host and guest need to have the necessary kernel modules.


7. **Firewall and SELinux**: Check if your system's firewall or SELinux settings are blocking the operation of Virtio-FS. Adjust your firewall rules or SELinux policies if needed.


8. **Review Documentation**: Review the official documentation for Virtio-FS, QEMU, and any associated software to ensure that you are using the correct options and configuration.


9. **Community Resources**: Check community forums and mailing lists related to QEMU and Virtio-FS for discussions and solutions related to specific issues you're facing.


10. **Updates**: Ensure that you are using the latest versions of QEMU and Virtio-FS, as updates may contain bug fixes and improvements.


If you provide more specific details about the issues you're encountering, any error messages, or your current launch script, I can provide more targeted assistance.

bad character U+002D '-' in my helm template

 In Helm templates, the hyphen character (`-`) can sometimes be treated as a reserved character, particularly when defining values or labels. To include a hyphen character in a Helm template without issues, you can use one of the following approaches: 1. **Quoting the Hyphen:**    You can enclose the hyphen in double quotes, like this:    ```yaml    key: "-"    ```    This way, Helm will interpret the hyphen as a string rather than an operator. 2. **Using Backticks:**    If you need to use the hyphen within a Go template function or inside backticks, you can escape it with a backslash (`\`), like this:    ```yaml    value: `{{ .Values.someField | printf "%s \\-" }}`    ```    The backslash prevents Helm from interpreting the hyphen as a special character. 3. **Variable Assignment:**    Assign the value to a variable and use it. For example:    ```yaml    {{- $hyphen := "-" }}    key: {{ $hyphen }}    ```    This way, you can use the variable `$hyphen` wher

GitLab pipeline stopped working with invalid yaml error

 When your GitLab pipeline has stopped working with an "invalid YAML" error, it means there's a problem with your `.gitlab-ci.yml` file. This could be due to syntax errors, incorrect indentation, or other issues in your pipeline configuration. Here's how to troubleshoot and resolve this issue: 1. **Check for Syntax Errors**:    Carefully review your `.gitlab-ci.yml` file for any syntax errors. Common issues include missing colons, indentation problems, or mismatched quotation marks. Use a YAML linter or an online YAML validator to identify and correct syntax errors. 2. **Indentation**:    YAML relies heavily on proper indentation. Make sure that all lines within the same block have consistent indentation (typically using spaces, not tabs). Incorrect indentation can cause YAML parsing errors. 3. **Dashes and Lists**:    Ensure that you use the correct syntax for lists (arrays) in YAML by starting each item with a dash (`-`). Be consistent with your use of dashes throug

How do I add a printer in OpenSUSE which is being shared by a CUPS print server?

 To add a printer in openSUSE that is being shared by a CUPS print server, you can use the following steps: 1. **Ensure CUPS Client is Installed:**    Make sure your openSUSE system has the CUPS client tools installed. You can install them using the following command:    ```bash    sudo zypper install cups-client    ``` 2. **Discover Available Printers:**    Use the `lpinfo` command to discover available printers on your CUPS print server. Replace `cups-server-hostname` with the hostname or IP address of your CUPS server:    ```bash    lpinfo -v -h cups-server-hostname:631    ```    This command should list the printers shared by the CUPS server. 3. **Add a Printer:**    Use the `lpadmin` command to add a printer. Replace `printer-name` with the name of the printer you want to add and `printer-uri` with the URI obtained from the `lpinfo` command:    ```bash    sudo lpadmin -p printer-name -E -v printer-uri    ```    For example:    ```bash    sudo lpadmin -p MyPrinter -E -v socket://cu
