Hi,
I'm trying to checkpoint and restart a Synopsys VCS simulation that runs
concurrently with a Virtual Machine (QEMU) that communicate together over TCP
sockets.
I can successfully checkpoint and restart the Synopsys VCS simulation alone,
but not the QEMU. The restart of QEMU gives the following:
[root@demeter qemu-1.2.0]# /opt/dmtcp/dmtcp-1.2.8/bin/dmtcp_restart
ckpt_qemu-system-i386_1d4a8584596cf84-15246-5231ce7f.dmtcp
dmtcp_checkpoint (DMTCP + MTCP) 1.2.8
