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.
