Thread: openSUSE 11 Xen with XP... processor support????

  1. #1

    Default openSUSE 11 Xen with XP... processor support????

    I recently installed openSUSE 11 and Xen. If I try to create a virtual machine to my existing XP setup (it's there and bootable from the Suse boot menu), it says that my processor does not support full virtualization. Is there any way to get this to work????

    Thanks.

    If your processor and motherboard support it then enable it in the BIOS.
    If it doesn't, get a new processor and/or motherboard.

    Good luck.

    Like Ab mentioned, it's a setting that should be enabled in the BIOS, mostly simply called 'virtualization', V(T) support or similar.
    If you have a newer system (3 years or younger) it's quite likely you have this setting.
    Have a lot of fun!

    Also, regardless of how new your system is, this setting is almost
    guaranteed to be disabled by default. I have no idea why this is still
    done but it is.... even on brand new Dell 2950 servers as of two weeks ago.

    Good luck.

    so XEN not working with processors that could not have VT?

    it seems I could understand this never... why i can run VirtualBox running winxp and cad on it and it will be workable, but XEN I could not run on same system... athlon 2500+ it is really old... but this is not the answer did you agree?
    this is not very important cause VirtualBox and VMware player exist but I did not understand...

    Virtualbox is more akin to Vmware than it is to Xen. Virtualbox and Vmware create a full virtualized computer that the operating system then is installed in. Xen goes with a different approach called para-virtualization. Para-virtualization is faster and scales better but requires either a modification to the OS kernel or for the CPU to have a virtualization hardware component built into the chip. Xen freely provides the modifications for Linux kernels but they leave it up to commercial vendors like Novell and Citrix to add support for Windows and others for a fee. If you have a VT enabled CPU, then it shouldn't matter.

    Both AMD and Intel have a virtualization technology component on most but not all of their multi-core CPUs. This feature is usually disabled by default in the BIOS as mentioned in earlier posts. Current versions of Vmware will now take advantage of VT enabled CPUs so there may not be much performance advantage to XEN anymore. I don't know if Virtualbox is aware of that technology yet.

    I also have this problem. I have verified that the virtualization settings are enabled in the BIOS, and xen still says that the processor does not support virtualization. This is a brand new pc. Could it be that xen is a little behind in recognizing the newer processors?

    Can Xen and Vitualbox co-exist on the same server? I have VBox installed and wanted to give Xen a try. I have a full blown VT Server.

    Its uncertain, as there might be other factors too. visualization using this method is very tricky so I heard.

    Co-exist, yes.... run toghther, not sure.

    Installing Xen won't brake anything. It will however modify your network configuration to create a network bridge that your guests (domU) will be using.

    If or not you can run Xen and Virtualbox at the same time depends... As Xen uses it's own modified Linux kernel some modules (like the vbox driver) might not load correctly.

    You can however give Xen a whirl. If you want to revert back, just reboot and choose the normal kernel (Installing Xen will give you two kernel boot options, one for Xen one for Desktop/Linux).



    Cheers,

    Have a lot of fun!
