[libvirt-users] qemu - could not load kernel and dynamic ownership setting



Hi,

I am getting following 'qemu: could not load kernel' error while trying to create a new VM using virt-install or virt-manager. The software versions are as follows: CentOS 6.2,  Libvirt 0.9.4,  qemu-kvm 2:0.12.1.2-2.209.el6_2.1. 

The qemu.conf has disabled dynamic_ownership setting.  The VM instantiation has worked fine before when dynamic_ownership was enabled (default). So is this error related to dynamic ownership being disabled? I appreciate any help on how to debug this error further. 

Also, is there any documentation on why/when dynamic_ownership setting should be used? We have enabled it to figure this out through some test installs but right now unable to move further with the install step itself. 

{{{

--os-type=linux \
