Description Brian Lane 2013-01-11 19:15:28 UTC 
Description of problem:
When running virt-install using a serial console it will not start to boot unless the console has been connected. And, if you wait around 15 seconds before connecting the console you need to hit a key before the kernel will start to boot.


Version-Release number of selected component (if applicable):
python-virtinst-0.600.3-2.fc18.noarch

How reproducible:
Always

Steps to Reproduce:
Test script attached

cmdline is:

virt-install -n console-test -r 1024 --noreboot --noautoconsole --graphics none \
--disk path=$ISO,device=cdrom \
--extra-args "stage2=live:CDLABEL=Fedora\x2018\x20x86_64 console=tty0 console=ttyS0,115200n8" \
--location $ISOMOUNT

Thanks for the report Brian, I can reproduce.

Amit, this is what the flow control patches are supposed to fix, right? Patches my need tweaking for 1.2 (or I screwed up the backport).
Comment 3 Amit Shah 2013-01-24 10:37:24 UTC 
Can you fetch the qemu command line generated by the virt-install command?  I'm not sure where to look, Cole, you can help perhaps.
Comment 4 Amit Shah 2013-01-25 04:10:11 UTC 
I think this is fixed upstream by b37a2e4576530597dda880387e3f4da52c42b5b5

For reference, libvirt sticks qemu command line (and not much else) in /var/log/libvirt/qemu/<name>.log

Though I can reproduce with a hacked ISO I have that adds console=ttyS0:

qemu-kvm -cdrom boot_with_serial.iso -serial pty

Yep, that fixes things for me. Thanks Amit!

bcl, I'll push a build early next week.
