Unknown OS type hvm

  • After fresh installation of Virtual Machine Manager, when I created a new VM it displayed this error unknown os type.

    zoomify

  • This was because all qemu packages were not installed. So I installed all qemu packages.

    yum install qemu*

    zypper install qemu*

  • It should have installed all the packages, but somehow it didn’t installed qemu-kvm, due to which it displayed this error while creating new VM.

    Cannot check QEMU binary /usr/bin/qemu-kvm: No such file or directory

  • It was all because qemu-kvm was not installed.

Install qemu-kvm

  • Start yast.
  • Choose Virtualization -> Install Hypervisor and Tools.
  • Select KVM and confirm with Accept.
  • Confirm to the list of packages that is to be installed with Install.

  • Agree to set up a network bridge by clicking Yes.

    Note

    • It is recommended to use a bridge on a VM Host Server (virtual machine host).
    • If you prefer to manually configure a different network setup, you can safely skip this step by clicking No.

  • After the setup has been finished, reboot the machine as YaST suggests. Alternatively, load the required kernel modules manually and start libvirtd to avoid a reboot.

    • Enable kvm module

      modprobe kvm-intel                                    // on Intel machines only

      modprobe kvm-amd                                    // on AMD machines only

    • Enable vhost-net module

      modprobe vhost-net

    • Restart rclibvirtd.

      rclibvirtd start
