Please see inline comments.Keep in mind that there is some debug output put in /tmp by the nodemanager currently (like /tmp/20037.{out|err}). It should have something there, because I see that the nodemanager tries to create VMs.My /tmp/<pid>.err file looks like this: /etc/qemu-ifup.1: could not launch network script qemu-system-x86_64: -net tap,ifname=tashi4.0,vlan=1,script=/etc/qemu-ifup.1: Device 'tap' could not be initialized The /etc/qemu-ifup.1 script looks like this: #!/bin/sh /sbin/ifconfig $1 0.0.0.0 up /usr/sbin/brctl addif mybridge $1 exit 0
Is /etc/qemu-ifup.1 executable (chmod 755 /etc/qemu-ifup.1)? Are you running as root? Do you have the tun module loaded? http://turbolinux.org/2011/05/etcqemu-ifupcould-not-launch-network-script-could-not-initialize-device-tap/ Greetings, Michael.
