You have several choices. To read the log files: virt-cat Guest /var/log/messages # or /var/log/dmesg etc or: guestfish --ro -i -d Guest ><fs> less /var/log/messages For recovering the guest: virt-edit Guest /boot/grub/grub.conf or: guestfish -i -d Guest ><fs> emacs /boot/grub/grub.conf or: virt-rescue Guest ><rescue> mount /dev/vg_foo/lv_root /sysroot ><rescue> mount /dev/vda1 /sysroot/boot ><rescue> vi /sysroot/boot/grub/grub.conf We don't have a way that you can read 'dmesg' if it just exists in memory (hasn't been written to disk). We _used_ to have this capability, and will do so in future, but not right now.
