[Qemu-devel] [Bug 1721952] [NEW] Network issue above 2.5.1.1

[Joan Moreau]

Public bug reported:

Hi,
WHen running a QEMU guest (Windows7) on a linux x86-64 server, the network 
stops working after some time for any version above 2.5.1.1

In 2.5.1.1, all is fine (no issue with network)
Any version ablve (trying 2.10.1 now), the application in windows stops 
accessing the internet after a while

THis is my starting line:
/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=winpro.qcow,index=0,media=disk,format=qco
w2 -m 4096 -vga vmware -vnc :3 -k en-us -device e1000,netdev=nic1 -netdev 
user,id=nic1,smb=/data/vps/files/,hostfwd=tcp::10053-:10053,hostfwd=tcp::3387-:3389
 -rtc base=utc,clock=host -daemon
ize

Thisis my configure line:
./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --enable-kvm 
--disable-gtk --disable-xen --disable-user --enable-vnc-sasl --disable-libusb 
--disable-debug-info --disable-spi
ce --enable-lzo --enable-pie --disable-werror --enable-linux-aio 
--enable-vhost-net --disable-tcmalloc --enable-vde --enable-nettle 
--disable-smartcard --enable-curl
