libvirt users - Apr 2014 - Re: Libvirt qemu permission denied error

Hello,

I am trying run a simple VM (qemu1.4.2) on RHEL 6.5 through libvirt (0.10).
virsh create throws the error:

*​error: Failed to create domain from vm1.xml*
*error: internal error process exited while connecting to monitor:*​

The libvirt log for VM shows:


*libvir:  error : cannot execute binary /usr/bin/qemu-system-x86_64:
Permission denied*

​I am running VM as root and all disk images/ISOs required for VM are
read/write/executable.

The disk images may be accessible, but did you check that the actual
qemu binary was accessible?  Given that you are using RHEzL, have you
considered opening a support ticket with Red Hat?

The qemu binary is accessible as I can create VM through command line. That
is why I thought it may be a libvirt issue.

I have also contacted Red Hat support and will post my findings here if the
issue is resolved.
