Thread: Suitability of OpenSUSE for workstation virtualization host with KVM?

  1. #1

    Default Suitability of OpenSUSE for workstation virtualization host with KVM?

    Hi All,

    Can someone offer any advice as to whether OpenSUSE is well suited or not to use as a virtualization host for KVM? We have tried out various other Linux distros but none of them seem to work completely in this situation. Requirements and difficulties are:
    • Workstation Virtualization - both host partition and VMs all running on same physical machine
    • Mixed Windows and Linux guest operating systems
    • Access to NTFS partitions on same machine
    • Access to Windows network
    • Clean basic install for host KVM partition without Browser, Office or other unnecessary accessories and additions.
    • GUI required as this is for workstation virtualization
    • Support for dual-screens on nVidia GPU


    Is there any known difficulties or anything in the above which suggests that OpenSUSE might not be the most suitable host OS for this purpose or should I download and give it a try?

    Thanks,
    Nick

    Giving it a try would be easiest. I've never used KVM but I think it should be easier to do on CentOS 6 as RedHat is mostly involved with KVM development. They may set some pitfalls, however, to motivate people buying RedHat instead of using CentOS.

    Thanks for your comments Greg. Yep, that is what concerns me about using CentOS for the purpose, I seem to recall reading about certain functionality which is not present in the current version of CentOS, probably for the reason you described.

    Hi. I have been using openSUSE, Fedora, Ubuntu and Arch Linux as kvm hosts without noticeable differences. What matters is the version of libvirtd, not the OS.
    You might want to have a look of these two scripts:

    They are also included in the package vmscripts available in my repo: home: please_try_again > vmscripts

      Probably, but I don't install Windows.

      Yes with s samba server running on the host.

      Yes, through samba client on the guest.

      Yes, with vm-create. Here some examples:

      I should post more recent ones ... but no time

      Of course! Anything. Install FreeNX or No Machine NX on the guest! It's much much faster than VNC.

      I have no idea ... but I would say: probably not.

    I was thinking more of how to get a clean Server Host partition rather than the Guest VM.

    What do you mean by "a clean Server Host partition"?

    Not quite sure how else to describe it, the KVM Host (parent) install as opposed to the Guest (child) virtual machines which run inside the host partition. Looking for an install which reduces the attack area of that Host partition by installing only the minimum required.

    Well, the virtual machine (guest) is inside a file and this file can be on any partition on the host or even on a remote host. You can put your virtual machines on a separate partition. That's what I do. If you're looking for a minimum installation on the host, there are some distros which focus on kvm. They are usually installed on dedicated servers. I have tested one of them but I cannot remember the name. But there are some. That's problably what you're looking for. They are usually based on RedHat. But you can achieve the same result with Arch Linux or any distro. You only need to install qemu, libvirt and virt-manager (if you want a GUI administration tool).
