Maybe this should go to the qemu mail list, but I have domains configured to dump to serial. Works fine I see Grub menu/kernel messages and the like, but the "bootmenu" listing only shows up over vnc. Is there a way to have that show up over serial? I definitely can hit up the qemu mail list as well if inappropriate for here

Hi, I have installed Debian Buster with encrypted LVM so apon installation my root partition is encrypted. So far so good but as soon as I encrypt the boot partition, after reboot the OS won't start. If I start the drive directly with qemu, it works but it looks like Libvirt is somehow not able to deel with it. What am I missing? -- John Doe

...e the VM, but then the OS inside doesn't boot at all. I tried to go deeper into debugging and it seems that the VM cannot pass SeaBIOS anymore. It gets stuck in seabios, it seems. No "Booting" sentence displayed, only version of SeaBIOS, when I watch VNC ouput. I tried to use <bios useserial='yes'/> with a console to the VM. Nothing is displayed on the console. Here are the specs of the machine: -> Ubuntu 12.04LTS up to date -> libvirt 0.9.8-2ubuntu17.19 -> kvm 1.0+noroms-0ubuntu14.15 -> seabios 0.6.2-0ubuntu2.1 The ethernet card I try to attach is: Broadcom Co...

Hi For the latest seabios version, it said: Support for vga emulation over a serial port in SeaBIOS (sercon). So I want to know how can I find the application of this feature in libvirt? And whether my understanding is correct? There are no related instruction on the website: https://libvirt.org/ My understanding: (1) The feature means: we can set this the IO address of a serial port to

Hi: Anyone knows how to configure seabios with libvirt? Or Can I configure seabios in XML file? I know that could configre seabios with "qemu-system-x86_64 -fw_cfg",but how to with libvirt? thanks! dw
