[ovirt-devel] Running VM reports error when using qemu-2.5.1 replace qemu-kvm-ev 2.3.0 in vdsm 4.18.11

[lifuqiong]

Hi all,

         I installed vdsm 4.18.11 in ovirt engine 4.0.2,  uninstall
qemu-kvm-ev 2.3.0 with rpm -e -nodeps,  and then compile and make install
qemu 2.5.1; 

 

The vdsm host is still up in ovirt engine, but when "Run" Vm in this vdsm
host, it reports an error as:

 

internal error: process exited while connecting to monitor: Could not access
KVM kernel module: Permission denied

failed to initialize KVM: Permission denied

 

Here is the error log in VM:
