virsh error: driver is not whitelisted

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



I'm using virsh to instance a VM in my environment, but I'm running on some issues. I created the following domain file:

<domain type='kvm'>
  <memory unit='KiB'>4194304</memory>
  <currentMemory unit='KiB'>4194304</currentMemory>
      <page size='2' unit='M' nodeset='0'/>
  <vcpu placement='static'>2</vcpu>
    <vcpupin vcpu='0' cpuset='4'/>
    <vcpupin vcpu='1' cpuset='5'/>
    <emulatorpin cpuset='4,5'/>
    <type arch='x86_64' machine='pc'>hvm</type>
    <boot dev='hd'/>
  <cpu mode='host-model'>
    <model fallback='allow'/>
    <topology sockets='2' cores='1' threads='1'/>
<cell id='0' cpus='0-1' memory='4194304' unit='KiB' memAccess='shared'/>
    <disk type='file' device='disk'>
      <driver name='qemu' type='qcow2' cache='none'/>
      <source file='/root/cirros-0.3.5-x86_64-disk.img'/>
      <target dev='vda' bus='virtio'/>
    <disk type='dir' device='disk'>
      <driver name='qemu' type='fat'/>
      <source dir='/usr/src/dpdk-stable-16.11.1'/>
      <target dev='vdb' bus='virtio'/>
    <interface type='vhostuser'>
      <mac address='00:00:00:00:00:01'/>
<source type='unix' path='/var/run/openvswitch/dpdkvhostuser0' mode='client'/>
       <model type='virtio'/>
      <driver queues='2'>
        <host mrg_rxbuf='off'/>
    <serial type='pty'>
      <target port='0'/>
    <console type='pty'>
      <target type='serial' port='0'/>

When I run:

virsh create domain.xml

I got the following error:

error: Failed to create domain from domain.xml
error: internal error: qemu unexpectedly closed the monitor: 2017-04-17T17:00:37.012369Z qemu-kvm: -drive file=fat:/usr/src/dpdk-stable-16.11.1,if=none,id=drive-virtio-disk1,readonly=on: Driver 'vvfat' is not whitelisted

If I comment the disk that cause this error, the instance starts without error. Is there a way to whitelist this vvfat driver to instance this VM?

And the strange thing about this error is that when I check the available drives, there is vvfat in the list:

/usr/libexec/qemu-kvm -drive format=?
Supported formats: ftps http null-aio null-co file quorum blkverify vvfat blkreplay qed raw qcow2 bochs dmg vmdk parallels vhdx vpc https sheepdog host_cdrom ssh host_device nbd gluster qcow iscsi rbd tftp ftp vdi blkdebug luks cloop

Here some information about the environment:

cat /etc/redhat-release
CentOS Linux release 7.3.1611 (Core)

virsh --version

/usr/libexec/qemu-kvm --version
QEMU emulator version 2.6.0 (qemu-kvm-ev-2.6.0-28.el7_3.6.1), Copyright (c) 2003-2008 Fabrice Bellard

Thanks in advance for the help
