If your host system uses Time Stamp Counter and Virtual Machine guests use kvm-clock, then you should not use ntp on the guest. But what if you sync the physical host to a good Internet time source and just sync the virtualized guest to itself?

virsh won’t let me query information, but I do know the vm names I wish to start and I have a simple ssh shell on the host machine. So lets give it a shot.

The only problem i’ve had with LXDE and Mint is that running as a guest in VirtualBox, the guest additions will not install properly. I tried mounting the additions from the host and installing them, no dice. I tried installing from the software repositories using the aptitude update manager, no dice. So it didn’t work out of the box for me, but a quick recompile did the trick. No moving around files or manipulating configurations are necessary, just recompile for the running kernel and you’re in business.

Linode is cheaper than many of the other big names in VPS and they offer plenty of storage and bandwidth too. Monitoring their status page for a few days/weeks should give you a good idea of the kind of downtime you’ll be looking at.

VirtualBox can’t operate in VMX root mode. Please disable the KVM kernel extension, recompile your kernel and reboot. You might see this VirtualBox error when trying to start a virtual machine or create a new one.

These two scripts are called when you start a qemu or kvm virtual machine. I removed the openvpn –mktun and –rmtun commands because qemu handles it for you.

So you want to setup networking so virtual machines will have access to the outside world through your hosts network connection. To do this you’ll need to share your host’s external interface with virtual machines through a bridge. A bridge can join two network segments and be used to inspect all Ethernet frames that pass between them. Create a bridge and a tunnel interface. Assign the tunnel and your host’s Ethernet interface to the bridge. Connect the bridge to the outside world. Your host uses the network card in promiscuous mode to handle packets for other interfaces connected to the bridge.

QEMU is a generic and open source machine emulator and virtualizer. When used as a machine emulator, QEMU can run OSes and programs made for one machine architecture on a different machine architecture. This is different than VMware, VirtualBox, or Hyper-V where you’re running different operating systems on the same architecture.
