This is a quick guide to mounting a qcow2 disk images on your host server. This is useful to reset passwords, edit files, or recover something without the virtual machine running.
Step 1 - Enable NBD on the Host
modprobe nbd max_part=8
Use this as an example on how to start the virtual console without the need of Java Web Start or accessing it from the web interface. | |
You can use the user and password that you use for the web interface. | |
You need an old JRE... I used 1.7.0_80 from the Server JRE package, also I have tested successfully 1.7.0_79 with MacOS. | |
You don't need to install it, just extract it or copy the files in "jre" folder. | |
Open the viewer.jnlp file that you get by launching the virtual console from the web interface with a text editor. | |
Note the urls to the jar files. Download the main jar file avctKVM.jar and the libs for your operating system and architecture. | |
Extract the dlls (.so Linux, .jnilib MacOS) from the jar libs. |
