  1. Well, I use the Open Source Xen, mostly due to Citrix's gayness And that works fine. Problem with most people/implementations/users is that it takes a bit of time to learn how to configure things properly. In the world of computing, everything is possible, the only limiting factor is people. If you can't or won't configure/setup things yourself, it's not possible to do the three-fold bare-metal setup. There are a few GUIs but mostly it's all about commandline and text configuration files. VMDK is for VMware only. No go there, sorry about that. For Xen, you actually use real virtualisation; you have a physical disk, and you can 'give' it to the Guest OS, and that gives you 100% hardware access to that disk. Or you can use it as a logical disk with LVM, and split it in a few pieces. The Guest OS will think it's a real disk (but it will show up as a Xen SCSI disk), and it will work like a real disk. If the Guest OS is shut-down, you can actually just mount the disk, and all the files etc are there. Mac OS X installation on Xen still requires the OSx86 way, so if you don't want to do that, stop right there
  2. Yes, that would work. But bear in mind, a storage unit like a hard disk drive has a limit on how fast it can do things. If you use one system, that system can take that limit to itselt. If you use three systems, you might only get 1/3 of the speed. However, usually you are only active in one environment. So if you have two or three systems running, and only one is actually being used, it might work pretty well. I have set-up single-disk virtualisation systems (where performance wasn't the issue), and it does work if you don't task all systems at once.
  3. With mainstream linux distributions, you don't need to download installer binaries or other stuff -- everything comes with the repositories made for those distributions. Debian uses a system with APT and DPKG, whilst Fedora uses RPM. To install anything, just open de software manager, search for the things you need, select them, press install, and it will automagically happen. Everything will be downloaded, checked and installed. Sometimes a new kernel or a kernel module is required to run new software, in which case you might need to reboot. Linux rarely needs to be rebooted, that might be good to know. You might want to consider something like virt-manager, it's supposed to be a nice GUI frontend for virtualisation systems (like KVM, Xen etc). I use manual setups myself (allows to fine-tune everything).
  4. I use Debian Squeeze, but that might be too complex to begin with. Fedora is much easier. The MSI installer problem is simple: the package author doesn't want you installing it on server versions.
  5. Install a stable linux distro with Xen 4. Debian has it, Fedora too, and SuSE as well.
  6. It's not that hard to do. But using windows drives de cost up to crazy heights! And there's not a single bit of performance over Xen... What is hard, is doing that on a laptop, since most laptops have broken firmware or non vt-d hardware.
  7. There is no source code, therefore I don't trust it. Even Apple has much of it's Darwin/XNU kernel source downloadable. Xen is completely open. KVM is open. ESXi is lame and Hyper-V is lame as well. If people want to play with gui's, they should stay in userland with desktops.

    TRIM support

    Even if you could, your system wouldn't go faster..

    TRIM support

    I know But this TRIM stuff is more a marketing thingy than a technology boost. It's nice if you have a need for block-level garbage collection, but it seems that only NTFS really suffers from SSD's without TRIM, or controllers that don't pass TRIM commands. Since Mac OS X uses HFS+J as default, I don't really see why you would care right now.

    TRIM support

    Well, I don't care. My system isn't getting slower on my Vertex2 so I don't really need TRIM.
  11. ESXi is just a lame ass implementation of what Xen had 2 years ago. DirectPath is not even a real thing and VT-d is the only stuff that is on the menu in this case XenClient and XenServer are almost the same, it's Xen with some corporate n00bsauce spilled over it. A laptop with VT-d mobo, firmware, cpu, chipset and a xenified linux distro or just the kernel to have a microhypervisor will suffice, but needs two disks in raid0 or two seperate SSD's. A couple of ExpressCard/USB/FireWire GPU's would be required too. Windows won't work (only if you assign the internal video to it) unless windowed.
  12. Yes, Xen is VT-d aware, and the video cards are actually directly connected to the guest VM's. (DomU's as they are called in Xen). You can directly pass hardware to guest operating systems, and if it's video hardware, the video output is actually on the video hardware, instead of a windowed console viewer. Win7 sees the old ATI 9700 directly as it's main PCI video card, Mac OS X sees the HD4580 as it should (after some upgrading and driver hacking). Mac OS X has the audio hardware as well, and one USB controller for quick fixes and external drives. Windows 7 doesn't get once, since I don't like it. Windows Server 2008 R2 works just as good. Speed is near bare-metal on Windows 7, but still not maximum on the Mac OS X guest, it's like a 2008 Mac Mini (that's the best I can give as a speed marker). I don't have fast networking on Mac OS X yet (I have a hacky serial loop and a fake USB netcard), so that's not optimal either. Since my workload is getting worse every day, I don't have much time to spend on the Xen setup.
  13. Xen will do what you need. I have it set-up: Debian Linux 6 with Xen 4.0 (both free) on a Xeon X3232 and a DQ45CB with onlt 8GB of RAM, internal Video, PCIe Video and PCI (non-e) video, so three video cards. Synergy and one keyboard/mouse; this gives you: Three displays (with Linux on the internal video), one for Linux, one for Mac OS X (currently just at 10.5.2) and one for Windows 7. The mous and keyboard will actually work on all of them, I can move the pointer from screen to screen and the keyboard actually follows that. When it boots, you get to see Linux booting on the internal DVI connected LCD, then once it's at ±40%, Xen starts Windows 7 and Mac OS X as well. Windows 7 boots a little faster at this moment, but that's probably because 10.5 isn't as fast as 10.6, because 10.6 pwns Windows 7. It's not hard to do, but you really need to know what you are doing! Use only VT-d capable hardware, and have plenty of RAM. Don't use disk image files but use LVM mapped volumes! (Or real disks if you have enough - I have it all running on a single RAID1 array of 2TB, Hitachi)

    OS X for SSE (qemu)

    Well, in that case (because it's the because-I-can-factor) I'll look into it I have been emulating and virtualising Linux, BSD, Mac OS X and Windows for a while now, so it must be possible. I'm even thinking about emulating Mac OS 10.6 on a PPC64 machine with QEMU
