SymQEMU Cannot Execute Programs with Socket Communication, While QEMU Works Normally

[whytolearn]

I encountered an issue where SymQEMU fails to execute programs that involve socket communication in scenarios using dnsmasq. When running the same program in QEMU, it functions without any issues. Specifically, programs that interact with dnsmasq for DNS resolution or DHCP services via sockets behave unexpectedly or fail entirely when executed in SymQEMU.

Thanks for the report. It would be nice if you could provide a small test case with exact commands you used. That would allow to reproduce.

I'm glad to receive your response. Here are my additional comments:

git clone git://thekelleys.org.uk/dnsmasq.git

cd dnsmasq
make

copy below to /etc/dnsmasq.conf

port=5353
no-daemon 
no-resolv 
interface=lo 
bind-interfaces 

cd src

path/to/sysqemu/build/qemu-x86_64 ./dnsmasq

open other terminal

dig @127.0.0.1 -p 5353 google.com

then it will down

path/to/qemu/build/qemu-x86_64 ./dnsmasq

it is work
