HI I have install openstack using devstack.I'm using multinode setup with one controller node and one compute node.I'm able to launch VM from openstack dashboard onto the controller node. At the controller node when i do ps -ef | grep nova,the following appears..
ps -ef | grep nova root 799 798 0 11:48 pts/22 00:00:00 sg libvirtd /usr/local/bin/nova-compute --config-file /etc/nova/nova.conf shiv 801 799 0 11:48 pts/22 00:00:55 /usr/bin/python /usr/local/bin/nova-compute --config-file /etc/nova/nova.conf shiv 1233 1232 1 11:48 pts/23 00:03:45 /usr/bin/python /usr/local/bin/nova-conductor --config-file /etc/nova/nova.conf shiv 1457 1233 0 11:48 pts/23 00:00:45 /usr/bin/python /usr/local/bin/nova-conductor --config-file /etc/nova/nova.conf shiv 1458 1233 0 11:48 pts/23 00:00:45 /usr/bin/python /usr/local/bin/nova-conductor --config-file /etc/nova/nova.conf shiv 1459 1233 0 11:48 pts/23 00:00:45 /usr/bin/python /usr/local/bin/nova-conductor --config-file /etc/nova/nova.conf shiv 1460 1233 0 11:48 pts/23 00:00:45 /usr/bin/python /usr/local/bin/nova-conductor --config-file /etc/nova/nova.conf shiv 1578 1577 0 11:48 pts/24 00:00:09 /usr/bin/python /usr/local/bin/nova-cert --config-file /etc/nova/nova.conf shiv 1880 1879 0 11:48 pts/25 00:00:10 /usr/bin/python /usr/local/bin/nova-scheduler --config-file /etc/nova/nova.conf shiv 2221 2219 0 11:48 pts/26 00:00:05 /usr/bin/python /usr/local/bin/nova-novncproxy --config-file /etc/nova/nova.conf --web /opt/stack/noVNC shiv 2431 2429 0 11:48 pts/27 00:00:00 /usr/bin/python /usr/local/bin/nova-xvpvncproxy --config-file /etc/nova/nova.conf shiv 2670 2669 0 11:48 pts/28 00:00:09 /usr/bin/python /usr/local/bin/nova-consoleauth --config-file /etc/nova/nova.conf shiv 2897 2895 0 11:48 pts/29 00:00:00 /usr/bin/python /usr/local/bin/nova-objectstore --config-file /etc/nova/nova.conf 122 13484 1 19 15:43 ? 00:00:02 /usr/bin/kvm -S -M pc-1.0 -enable-kvm -m 512 -smp 1,sockets=1,cores=1,threads=1 -name instance-00000003 -uuid cec324c7-2398-49b8-844b-08c6cca7fff3 -smbios type=1,manufacturer=OpenStack Foundation,product=OpenStack Nova,version=2014.2,serial=44454c4c-5600-1039-804c-c7c04f595831,uuid=cec324c7-2398-49b8-844b-08c6cca7fff3 -nodefconfig -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/instance-00000003.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=utc,driftfix=slew -no-kvm-pit-reinjection -no-hpet -no-shutdown -drive file=/opt/stack/data/nova/instances/cec324c7-2398-49b8-844b-08c6cca7fff3/disk,if=none,id=drive-virtio-disk0,format=qcow2,cache=none -device virtio-blk-pci,bus=pci.0,addr=0x4,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1 -drive file=/opt/stack/data/nova/instances/cec324c7-2398-49b8-844b-08c6cca7fff3/disk.config,if=none,media=cdrom,id=drive-ide0-1-1,readonly=on,format=raw,cache=none -device ide-drive,bus=ide.1,unit=1,drive=drive-ide0-1-1,id=ide0-1-1 -netdev tap,fd=19,id=hostnet0,vhost=on,vhostfd=20 -device virtio-net-pci,netdev=hostnet0,id=net0,mac=fa:16:3e:9b:09:3b,bus=pci.0,addr=0x3 -chardev file,id=charserial0,path=/opt/stack/data/nova/instances/cec324c7-2398-49b8-844b-08c6cca7fff3/console.log -device isa-serial,chardev=charserial0,id=serial0 -chardev pty,id=charserial1 -device isa-serial,chardev=charserial1,id=serial1 -usb -vnc 127.0.0.1:1 -k en-us -vga cirrus -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x5 shiv 14867 20602 0 15:43 pts/7 00:00:00 grep --color=auto nova shiv 31444 31443 1 11:47 pts/16 00:03:45 /usr/bin/python /usr/local/bin/nova-api shiv 31469 31444 0 11:47 pts/16 00:00:00 /usr/bin/python /usr/local/bin/nova-api shiv 31470 31444 0 11:47 pts/16 00:00:00 /usr/bin/python /usr/local/bin/nova-api shiv 31471 31444 0 11:47 pts/16 00:00:00 /usr/bin/python /usr/local/bin/nova-api I see the VM instance booted using KVM utility on to the controller node.
