Arch linux ( kvm/qemu virtualization ) failed to open libiscsi.so.4

I have fallowed the steps from Arch linux #KVM and #qemu

1)

sudo pacman -S 

then installed libs
   
    libvirt
    libiscsi
    libaio
    qemu
    qemu-arch-extra
    qemu-block-iscsi
    qemu-block-rbd
    qemu-block-gluster
   

2)

$ lscpu

check if VT-x is enabled

3) added the .conf file in the /etc/modprobe.d/ for the fallowing modules:

    network device (virtio-net)
    block device (virtio-blk)
    controller device (virtio-scsi)
    serial device (virtio-serial)
    balloon device (virtio-balloon)

4) I have included and run in the mkinitcpio.conf the modconf hook to load the modules in initramfs.

5) run

$ lsinitcpio 

 

I think is an issues here because in the output i don't see any virtualization module loaded:

6) When I run :

$ modinfo virtio-scsi

I get the fallowing answer :

    filename:       /lib/modules/4.5.4-1-ARCH/kernel/drivers/scsi/virtio_scsi.ko.gz
    license:        GPL
    description:    Virtio SCSI HBA driver
    alias:          virtio:d00000008v*
    depends:        virtio,scsi_mod,virtio_ring
    intree:         Y
    vermagic:       4.5.4-1-ARCH SMP preempt mod_unload modversions

----------

$ systool -v -m virtio-scsi

and here for same module I get an error msg:

    Error opening module virtio-scsi

----------

7) And when I try to create a qemu image

$ qemu-img create -f raw arch-qemu 8G

i get the fallowing error:

$ Failed to open module: libiscsi.so.4: cannot open shared object file: No such file or directory

Any help is appreciated !

Re: Arch linux ( kvm/qemu virtualization ) failed to open libiscsi.so.4

the solution i found is: downgrade the version of libiscsi to v1.14.0 http://unix.stackexchange.com/questions … 038#284038

FYI, the virtio modules are for qemu guest (virtual machine) not host.
