[Qemu-devel] [Bug 1656927] [NEW] Network (TCP) access regression

[Joan Moreau]

Public bug reported:

Starting a VM with

/usr/bin/qemu-system-x86_64 -machine pc-i440fx-1.7,accel=kvm -usb -usbdevice tablet -usbdevice keyboard -enable-kvm -cpu core2duo -smp 2 -drive file=winp
ro.qcow,index=0,media=disk,format=qcow2 -m 4096 -vga vmware -vnc :3 -k en-us -device rtl8139,netdev=nic1 -netdev user,id=nic1,smb=/data/vps/files/,hostfw
d=tcp::10053-:10053,hostfwd=tcp::3387-:3389 -rtc base=utc,clock=host -daemonize

in 2.5.1, all works fine

in any version after 2.5.1.1, the network terminate TCP connections
after a certain period .

To reproduce, starts an app that use always connected TCP sockets (I am
using Metatrader 4), let it run a an hour, the app does not realize the
TCP is out of order but the TCP connection is closed by QEMU

in 2.5.1.x, Metatrader works perfectly

Thank you for your help

[Thomas Huth]

Looking through old bug tickets... can you still reproduce this issue
with the latest version of QEMU? Or could we close this ticket nowadays?
