These are several things I experienced:</p> <ol> <li>can’t open palemoon</li> <li>successfully opened gns3, but Cisco IOS won’t boot.</li> <li>you need to install virtualbox-host-dkms and starting guest OS makes computer hang.</li> <li>QEMU got no issue so far.</li> </ol> <p>here’s the output of dmesg that i got: <br> <code>grsec: denied RWX mmap of &lt;anonymous mapping&gt; by /usr/bin/dynamips[dynamips:2864] uid/euid:1000/1000 gid/egid:100/100, parent /usr/bin/gns3server[gns3server:28267] uid/euid:1000/1000 gid/egid:100/100</code></p>
