Subject: [ovirt-users] Re: When I added the ovirt-node to the ovirt-engine through the web management interface, I get the following error: Host 172.16.41.100 installation failed. Failed to configure management network on the host. Host 172.16.41.100 does not comply with the cluster cluster-kvm networks, the following networks are missing on host: 'ovirtmgmt'

How can I check if my virtual machine supports nx?
 
[root@ovirt-node1 bin]# cat /proc/cpuinfo |grep nx
