The hang is probably due to that warning: it's not using 'kvm' acceleration, so the nested VM will be extremely slow Is your host intel? You probably need to enable nesting on the host. Uncomment the kvm_intel line in /etc/modprobe.d/kvm.conf , reboot, and try again (In reply to Cole Robinson from comment #2) > The hang is probably due to that warning: it's not using 'kvm' acceleration, > so the nested VM will be extremely slow > > Is your host intel? You probably need to enable nesting on the host. > Uncomment the kvm_intel line in /etc/modprobe.d/kvm.conf , reboot, and try > again yeah,it's intel.Here is the steps how I enable the nested vm on the host: 1)modprobe -r kvm_intel 2)modprobe kvm_intel nested=1 3)uncomment options kvm_intel nested=1 and reboot the host. [root@192 iscsi]# cat /sys/module/kvm_intel/parameters/nested Y Okay that's expected then. So if you were following test day steps they probably need to be updated |
