view external: query (cache) denied

I have registered my nameserver  at registrar. I have properly updated the zone file in the server. But for some reason while checking the dig result the new name-server details were not showing correctly. I have checked the logs and got the following error.
view external: query (cache) denied
Reason : in the view external section in named.conf, the entry for my domain was commented. Once I un-comment, everything was correct.
If you got similar type of error, check your named.conf and also check whether named.conf and the zone file is ok using the following commands
named-checkconf
named-checkzone domain.com /var/named/domain.com.db

The Xen-specific QEMU is called qemu-dm (short for QEMU device model) QEMU uses emulation; KVM uses processor extensions (intel-VT) for virtualization. Both Xen and KVM merge their various functionality to upstream QEMU, that way upstream QEMU can be used directly to accomplish Xen device model emulation, etc. Xen is unique in that it has paravirtualized guests that don't require hardware virtualization. Both Xen and KVM have paravirtualized device drivers that can run on top of the HVM guests. The QEMU hypervisor is very similar to the KVM hypervisor. Both are controlled through libvirt, both support the same feature set, and all virtual machine images that are compatible with KVM are also compatible with QEMU. The main difference is that QEMU does not support native virtualization. Consequently, QEMU has ...
