How can I check the history of all console logs starting from the first second of bootup
Gratings: Recently, I got an error while installing a guest, the error message is this,: [image: image.png] Is there a method to get the full log? I have tried to use virt-install --console, or attach <log file="/var/log/libvirt/qemu/guestname-serial0.log" append="off"/> to get the full log, but they didn't work.

My guess is that the kernel (and bios/uefi) was not set up to output to a serial console. You could use virt-install's --boot bios.useserial=on, or for the kernel to output on the console you might try kernel_args="console=ttyS0" if you're booting kernel directly, or --extra-args "console=ttyS0" if you're installing from --location. But that could be changed in the bootloader before choosing the kernel.
