I have recently been investigating different virtualization solutions such as linuxvserver, bsd jails and xen. |

This xen stuff is confusing the heck out of me at first I figured it was similar to a linux vserver setup (which I managed to get working just fine and with out much head scratching) but after a lot of scratching around I not so sure. |

It seems to me that while vserver is a modded linux kernel that xen is like a micro os that boots first and then boots into your dom0 (your primary os –with xennified kernel- whitch as I understand can control the others) |

Also it seems that you could have more than one of these privilidged osses installed at the same time sharing different parts of the hardware. |

It also seems that with new virtualization features in the latest intel/amd cpus that this hardware level sharing can be taken to a new level and that this would enable xen to run unmodified osses such as doors or freebsd (which currently has no xen dom0 support) |

My questions are: |
| 16 |
|
| 17 |
How would xen domUs compare to vserver? |
| 18 |
|
| 19 |
How does this hardware sharing stuff work? Would I be able to control the same raid controller from inside several virtual machines at the same time – or in turns if it comes to that? |

|
| 21 |
I suppose that a more usefull example would be the graphics hardware: would you be able to utilize the full potential of your graphics hardware in these virtual machines? |
