We found some problem that Huang....
The issue seems to be related to how the virsh command works. Look to
this command sequence:
=================
onead...@nubacesga-09-2:~/var/339/images$ ls -l
total 6291864
-rwxrwxrwx 1 oneadmin cloud 1065 Sep 22 12:53 deployment.0
-rwxrwxrwx 1 oneadmin cloud 1073741824 Sep 22 12:52 disk.0
-rwxrwxrwx 1 oneadmin cloud 5368709120 Sep 22 12:53 disk.1
-rwxrwxrwx 1 oneadmin cloud 405504 Sep 22 12:53 disk.2
onead...@nubacesga-09-2:~/var/339/images$
onead...@nubacesga-09-2:~/var/339/images$ virsh --connect qemu:///system
create deployment.0
error: Failed to create domain from deployment.0
error: internal error process exited while connecting to monitor: qemu:
could not open disk image /srv/cloud/one/var//339/images/disk.0:
Permission denied
onead...@nubacesga-09-2:~/var/339/images$ ls -l
total 6291864
-rwxrwxrwx 1 oneadmin cloud 1065 Sep 22 12:53 deployment.0
-rwxrwxrwx 1 root root 1073741824 Sep 22 12:52 disk.0
-rwxrwxrwx 1 root root 5368709120 Sep 22 12:53 disk.1
-rwxrwxrwx 1 libvirt-qemu kvm 405504 Sep 22 12:53 disk.2
=================
As you can see, the virsh command change the file owned at some
point..., and then the original user (oneadmin) can't read the image file
Anyone know how to arrange this issue????

Hello,
It looks like the problem is the NFS configuration. KVM runs as root
and needs read/write acces to the disk image. It this disk image has
been exported by NFS with the root_squash option (by default) the
local root user of the worker node won't have the permissions it
needs. You might wan't to change your /etc/exports in the frontend (or
NFS server) and configure it with no_root_squash.
Regards,
Jaime

Hi guys,
I encountered a qemu error while using ONE 2.0b. Does anyone have any idea
what is wrong?
"error: internal error process exited while connecting to monitor: qemu:
could not open disk image /srv/cloud/one/var//16/images/disk.0: Permission

My environment is:
Hardware:
Intel Xeon 2.93GHz x 2
12 GB memory
Software:
RHEL 6 beta (kernel 2.6.32)
qemu-kvm-0.12.1.2
SELinux is disabled on all nodes/front-end. So the root cause shouldn't be
SELinux. Below is error log from ONE.
