Title:
qemu exits with -11 when connecting to a port redirect before the
service starts listening
Status in QEMU:
Confirmed
Status in “qemu-kvm” package in Ubuntu:
Confirmed
Bug description:
This was detected initially as a crash in the auto upgrade tester.
The code of the upgrade tester basically spawns a kvm instance in the
background with a port redirect from localhost:54322 to tcp:22 in the VM, then
wait for that port to allow for a ssh connection before continuing the upgrade
testing.
In the past (Oneiric), all worked well but since Precise, we now get
qemu exitting with -11 at every single test :(
A quick reproducer is:
- start a VM that has openssh-server installed with: -net
user,hostfwd=tcp::54322-:22
- immediately start "ssh -p 54322 127.0.0.1" before the VM starts booting
(BIOS/GRUB state)
Then wait for sshd to start in the VM and qemu will exit with -11.
