I run it with iso image loaded from PXE server to RAM.
State data and cluster-wide configuration is on CIFS. Volatile RW data
is on tmpfs.

Probably you have some trouble with communication paths used for
interconnection. Try to mount /var/run to tmpfs. Or where is that socket
on linux?

	memset (&address, 0, sizeof (struct sockaddr_un));
	address.sun_family = AF_UNIX;
#if defined(COROSYNC_LINUX)
	sprintf (address.sun_path + 1, "%s", socket_name);
#else
	sprintf (address.sun_path, "%s/%s", SOCKETDIR, socket_name);
#endif

It is ENOENT (2)  /* No such file or directory */
Could you provide content of /proc/mounts?
