[BUG] QEMU VM Does Not Show Up Wth Virsh When Running `virsh --connect qemu:///system list --all` | Cannot Connect With Virt-Viewer #88

Closed VehementHam closed 10 months ago

There are no provided instructions on how to view the GUI of the VM of the QEMU image.

Perhaps you missed README.md? It's provided in oasis-qemu.tar.gz, and is also available inside the image at ~/README.md. The instructions are in the "Display server" section:

Display server

In graphics mode, you can launch velox with

swc-launch velox

velox works similarly to dwm, and has similar default keybindings:

  • Launch a terminal: Alt-Shift-Enter
  • Launch a browser: Alt-b
  • Launch dmenu: Alt-r
  • Cycle window focus: Alt-[jk]
  • Move window to/from master area: Alt-Enter
  • Change workspace Alt-[1-9]

Right, but when launch the VM in GUI mode, there is no GUI. All there is is the QEMU monitor.

I started the VM with the run script. After starting it. the VM does not show up when I run virsh --connect qemu:///system list --all. Also, virt-viewer does not detect the VM. There are no instructions on how to actually view the VM provided in the tarball ro the README.

I don't know anything about virsh or virt-viewer, but perhaps your qemu has some other default display? Try ./run -- -display sdl or ./run -- -display gtk.

starting a qemu process that is not related to libvirt wont show up in virsh. libvirt is an layer on top of qemu, to manage virtual machines. oasis comes with a script that starts a single qemu process, no libvirt is involved here. virt-viewer or any other virt-* tools wont work with it.

You have to check if your installed qemu version was actually compiled with graphics support

After looking around a little, my guess is that it is using -display dbus by default. I'm not sure how that's supposed to work, googling didn't help much. I think using some other qemu display should work.

Alternatively, if you are set on using virt-manager, you should be able to just add a new VM with the qcow2 image, and set it to boot the bzImage kernel directly. Set the kernel arguments to init=/bin/sinit root=/dev/vda ro, and make sure to enable various virtio drivers (virtio-keyboard, virtio-tablet, virtio-vga).

Thanks. I think I just compiled QEMU without the gtk USE flag.

Yeah
