The output of these seperately, and combined (total 3 files) are attached.
Guessing that there might a compiler flag problem, here's what our default
compiler uses while compiling packages:
The valgrind output was all fine - the warnings it issues are
all harmless.
The key is this message from the libvirt debug output:
DEBUG: util.c: virExec (dnsmasq --keep-in-foreground --strict-order
--bind-interfaces --pid-file --conf-file --listen-address 192.168.122.1
--except-interface lo --dhcp-leasefile=/var/lib/libvirt/dhcp-default.leases --dhcp-range
192.168.122.2,192.168.122.254)
libvir: error : internal error cannot execute binary 'dnsmasq': No such file or
directory
This missing 'dnsmasq' binary is what is causing the 'defunct' process
you see. If you install dnsmasq it should all work as expected
