If telnetd is installed and --telnet <port> is passed on the vm-run.sh command line, start a telnet server (directly connected to bash, no login) inside the VM(s) to be able to look into them when something is wrong. Use a user network in qemu with a single host forward from the specified port for this, listening only on 'localhost'. Please note that this provides unauthenticated access to the guest system from anything that can open a TCP connection on the host system. The guess system does have access to reading all files on the host that the user account running kvm has access to (and even write access if the default ROTAG ,readonly parameter is cleared). In other words, this option should not be used on any multiuser systems where kvm is run under user accounts that are not dedicated for testing purposes (i.e., do not have access to any files that should not be readable to everyone). This needs CONFIG_VIRTIO_NET=y in the guest kernel. For parallel-vm.py, the --telnet argument specifies the base port and each VM index (0, 1, ...) is added to it.
