Hi,
I'm recently debugging a qemu-kvm issue. I add some print code like
'fprintf(stderr, ...)', however I fail to see any info at stdio.
Anyone can tell me where is qemu-kvm logfile, or, what I need do to
record my fprintf info?
If you're running via libvirt, the log is in /var/log/libvirt/qemu.
If you're running from the command line and printf()s should end on
your terminal.
Thanks!
I run qemu-kvm from command line, but due to could not initialize SDL, I run
qemu command via VNC, like
1). test kvm-unit-tests: qemu-system-x86_64 -device testdev,chardev=testlog
-chardev file,id=testlog,path=apic.out -serial stdio -kernel ./x86/apic.flat
-cpu host
2). test kvm guest: qemu-system-x86_64 -smp2 -m 512 -hda test.qcow.img -cpu host
for case 1, there is some printf info of kvm-unit-tests on terminal but no
qemu-kvm printf info;
for case 2, no qemu-kvm printf info on terminal;
Best Regards,
