Subject: [dpdk-users] DPDK application fails to start in KVM
Date: Tue, 25 Aug 2020 22:32:18 +0530	[thread overview]
Message-ID: <CAL2oWpVW1Dj1bdQfB37DFovw8YusQOR7vwFEAP4a9Qy=KgcNUg@mail.gmail.com> (raw)

Hi,

I was using the DPDK library in a VM environment. But during the
application startup, the RTE initialization fails with the following error.

Is there any limitation of using DPDK libraries with KVM.

VM Details:
[roamware@roamware ~]$ hostnamectl
   Static hostname: localhost.localdomain
Transient hostname: roamware.com
         Icon name: computer-vm
           Chassis: vm
        Machine ID: 1ef1544480eb44a89d5b1f9eb8a8832f
           Boot ID: 282f8207b643405a89d13ea6d896745c
    Virtualization: kvm
  Operating System: Red Hat Enterprise Linux Server 7.2 (Maipo)
       CPE OS Name: cpe:/o:redhat:enterprise_linux:7.2:GA:server
            Kernel: Linux 3.10.0-327.el7.x86_64
      Architecture: x86-64

Error details:
ERROR: This system does not support "RDRAND".
Please check that RTE_MACHINE is set correctly.
EAL: FATAL: unsupported cpu type.
EAL: unsupported cpu type.

Jatin
