<P>Sorry for the late reply as I was on vacation.<BR>The below issue is happening becuase user "oneadmin" does not have rights to run the qemu process as a system instance.</P>
<DIV>Wed Apr 25 00:05:55 2012 [VMM][I]: <SPAN style="BACKGROUND-COLOR: rgb(255,102,102)">error: internal error process exited while connecting to monitor: kvm: -drive file=/srv/cloud/one/var//d</SPAN></DIV>

<DIV>Resolution:</DIV>
<DIV> </DIV>
<DIV><STRONG><FONT color=#ff0000>On the Node / VM HOST:</FONT></STRONG></DIV>
<DIV>1) First check the file <STRONG><FONT color=#0065cc>/var/log/libvirt/qemu/<VM-ID>.log</FONT></STRONG> and see if you can get any extra information.</DIV>
<DIV>for example, for VM-ID one-21, I give <EM>sudo cat /var/log/libvirt/qemu/one-21.log </EM></DIV>
<DIV> </DIV>
<DIV>2) add oneadmin ownership to qemu , by editing the file <EM>/etc/libvirt/qemu.conf and make below changes in "Red"</EM></DIV>
<DIV> </DIV>
<DIV><EM>sudo nano /etc/libvirt/qemu.conf</EM></DIV>
<DIV> </DIV>
<DIV># The user ID for QEMU processes run by the system instance.<BR><FONT color=#ff0000>user = "oneadmin"</FONT></DIV>
<DIV># The group ID for QEMU processes run by the system instance.<BR><FONT color=#ff0000>group = "cloud"<BR></FONT># Whether libvirt should dynamically change file ownership<BR># to match the configured user/group above. Defaults to 1.<BR># Set to 0 to disable file ownership changes.<BR><FONT color=#ff0000>dynamic_ownership = 0</FONT><BR></DIV>
<DIV>3) restart libvirt-bin and libvirt-d</DIV>
<DIV><EM>sudo /etc/init.d/libvirt-bin restart</EM></DIV>
<DIV> </DIV>
<DIV>libvirt daemon doesn't run automatically as a service on UBuntu11.10. I have to start it manually with </DIV>
<DIV><EM></EM> </DIV>
<DIV><EM>sudo libvirtd -d </EM></DIV>
<DIV> </DIV>
<DIV>4. Just check if everything is fine with,<BR>virsh -c qemu:///system list</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>Now resumit the VM, it should run.</DIV>

<DIV> </DIV>
<DIV><STRONG>Some additional hints:</STRONG></DIV>
<DIV>1. Before running a VM, as oneadmin user, try to source ~/etc/oned.conf , in the Node machine</DIV>

<DIV> sudo /usr/sbin/kvm-ok<BR>3. Add oneadmin to libvirtd and qemu. As <STRONG>oneadmin</STRONG> user provide the below commands</DIV>
<DIV>Adding user '<username>' to group 'kvm' ...</DIV>
<DIV> sudo adduser `id -un` kvm</DIV>
<DIV>Adding user '<username>' to group 'libvirtd'....</DIV>
<DIV> sudo adduser `id -un` libvirtd</DIV>

<DIV>Are you using the shared TM driver [1] in your system datastore? If so, please check that the datastore directory is properly exported, and that files created in the front-end have the correct permissions so the oneadmin account in the host can see them.</DIV>
