I can not answer the question about vmbuilder, because I have never used it. I would download the iso file for whatever Ubutnu 16.04 you want to use and then do, for example, this, from the same directory as the iso file: sudo virt-install -n desk_dev -r 8192 --disk path=/media/newhd/desk_dev.img,bus=virtio,size=50 -c xenial-desktop-amd64-20160320.iso --...

KVM networking is not my thing, really bugs me. That's why I had to dig a little deeper and found out that the "Carrier type" translates into the bond_use_carrier parameter in /etc/network/interfaces. Quote from here: use_carrier Specifies whether or not miimon should use MII or ETHTOOL ioctls vs. netif_carrier_ok() to determine the link status. The MII or ...

That's a really general question so here's a general answer. 1) is a bad idea. Those usb drives don't have good write amplification management. Just the generation of log files will kill the flash.

I had the same problem with the GPU. But from this post, I learned that I had to manually add the device in the blacklist.conf. First open sudo mousepad /etc/modprobe.d/blacklist.conf And add blacklist radeon And lastly, sudo update-initramfs -u Hope that helps.

Maybe this will work. Yet to try. So it looks like there is a need to add the following to a file named 'usr.sbin.libvirtd'.
