Debugging procedure

Reporting a bug

All reports should contain the following information. Please be sure to attach these files to the bug report.

  • uname -a > uname-a.log

  • cat /proc/version_signature > proc_version_signature.log

  • dmesg > dmesg.log

  • cat /proc/cpuinfo > proc_cpuinfo.log

  • If your linux guest can't boot, start kvm with  -serial file:kvm_guest_debug.log . 

    •  kvm linux_guest.img -serial file:kvm_guset_debug.log

      And edit grub to boot kernel with  earlycon=ttyS0 console=ttyS0  

       kernel /vmlinuz root=/dev/sda1 earlycon=ttyS0 console=ttyS0
