Doc Type: Bug Fix
Doc Text:
There was a typographical error in the command that verifies the Hyper-V para-virtualized drivers. Consequently, the hyperkvpd service failed to start, and it displayed an error message "Hyper-V drivers are not loaded". The command has been modified, and the "-q" option of the grep command-line utility has been removed. As a result, the service now successfully starts without an error.

Description Shengnan Wang 2013-06-26 06:02:06 EDT
Description of problem:
Failed to start the hypervkvpd service with error "Hyper-V drivers are not loaded".  There was a typo in the command that check the hyper-v pv drivers in the file /etc/rc.d/init.d/hypervkvd. It should be ture always with the command 'if [ -z "`lsmod | grep -q hv_utils`" ]'. It should be   'if [ -z "`lsmod | grep hv_utils`" ]'.


  if [ -z "`lsmod | grep -q hv_utils`" ]; then
                echo "Hyper-V drivers are not loaded."
                echo -n "Hyper-V KVP daemon not started:"


# lsmod |grep hv
hv_utils                5956  0
