Virsh insert cd rom iso

When I wanted to install new virtual machine using libvirt in my computer I always had to do these steps:. It was really annoying to edit the domain by hand just to select boot device. Fortunatelly I've found change-media virsh command, which helped me to overcome this problem. Show 2 more comments. Use virsh's qemu-monitor-command to pass the eject and change commands down to qemu.

First use "info block" to get qemu's device name for your cdrom. Keith Twombley Keith Twombley 2 2 silver badges 11 11 bronze badges. The "info block" command results in an error for me: "error: internal error cannot parse json info block: lexical error: invalid char in json text. Seems the syntax must have changed out from under me. I swear it worked when I wrote it. I tried out the syntax suggested by Joe Huss's answer and it works now.

Brian Brian 1. That's how I can mount a CD in the host. Ok, my mistake. Sign up or log in Sign up using Google. Sign up using Facebook. But it didn't. If I enable the loader line, as I marked as "suspicious" below, I would get an error message of "error: internal error: cannot load AppArmor profile 'libvirtd51d-3ba2-bf9be13dc'". I did that because I was trying the example given in libvirt's document here. Could anyone help me on that?

I don't understand why 'virt-install' can bring up the virt-viewer but my XML definition can't. I probably mis-configured the domain XML definition but I couldn't figure out which specific part I was wrong even if I'd tried to read as much documentation as possible.

Thanks for DanielB's help! The '--debug' argument of virt-install does reveal the information I need to solve this problem. Secondly, virt-install 's debug output suggests the desired way to bring up virt-viewer :. Here is one caveat which caused me to get stuck at the beginning: You don't have to start virt-viewer prior to the VM.

However, if you start VM first and then the viewer, the viewer screen may be a whole black one which may confuse you and make you think nothing is happening there. In this case, click the viewer window to let it get the input focus, then press 'Enter' key and you may get it refreshed and see what is there actually. Resizing the window doesn't force it to refresh. This doesn't seem to cause me any problems, but maybe it's the hint of other problems if virt-viewer doesn't work correctly for you.

A installation done by virt-install will make many API calls to accomplish its job. There are a few different reasons you might want to boot from a cdrom, however in my case I wanted to run a livecd so I could resize some partitions in the guest.

First put the iso for the cdrom somewhere on the host, in my example the file is called systemresucecd-x Next edit the guest definition to tell it about this image being mounted as the cdrom. To do this, on the host run.
