I tried to debug it with GDB and disassembled it, the invalid instruction
was "vzeroupper" which occurs at rte_eal_init, somewhere when initializing
pthreads.

Was the DPDK library compiled on a different machine and the used in the VM?
It looks like it has been compiled for native AVX (hence the vzeroupper).
Could you dump cpuinfo in the VM and see what instruction set the VM
supports?

If you are using qemu, the instruction set of the host CPU is used thanks to
	-cpu host
