Open Stack

Hi,

I am trying to launch instance on 2 node Openstack system.
Controller and compute both nodes are on Ubuntu Server 14.04 / intel i5
processor
while booting instance through command prompt as well as from dashboard,
I am getting following error in nova-compute.log

*qemuMonitorOpenUnix : 306 : failed to connect to monitor socket ; no such
a process*
*qemuprocesswaitformonitor : 1915 : internal error : process exited  while
connecting throu*
*Could not open backing file. Could not read image for determining its
format : Invalid Argument*

While launching instance  I can even see following error in syslog file
nbd8: unknown partition table
EXT4-fs (nbd8): VFS: Can't find ext4 filesystem
EXT4-fs (nbd8): VFS: Can't find ext4 filesystem
EXT4-fs (nbd8): VFS: Can't find ext4 filesystem
FAT-fs (nbd8): invalid media value (0x74)
FAT-fs (nbd8): cant find a valid FAT filesystem
block nbd8: NBD_DISCONNECT

the partition table with* fdisk -l *is as below
Device            Boot        Start            End                Blocks

      ee             GPT

The output of *lsblk *is as below

      0                part       [SWAP]

with *sudo parted* */dev/sda *the output is as below

Please help to resolve the problem. Is it due to GPT partitioning and How
can I make it understand underlying ext4 partition ? Let me know if need to
give any more details.
Thanks in advance
