[Qemu-devel] [Bug 1438572] Re: kvm does not support KVM_CAP_USER_MEMORY Please upgrade to at least kernel 2.6.29 or recent kvm-kmod (see http://sourceforge.net/projects/kvm)

[Paolo Bonzini]

This error has never existed in QEMU, only in the old qemu-kvm fork
which has been obsolete for about 5 years.  I'm closing this ticket.

** Changed in: qemu

Title:
  kvm does not support KVM_CAP_USER_MEMORY Please upgrade to at least
  kernel 2.6.29 or recent kvm-kmod (see
  http://sourceforge.net/projects/kvm)

Status in QEMU:
  Won't Fix

Bug description:
  We have a machine which is having QEMU+KVM on below configuration of linux
  uname -a
  Linux cairotrior 2.6.18-308.13.1.el5 #1 SMP Thu Jul 26 05:45:09 EDT 2012 
x86_64 x86_64 x86_64 GNU/Linux
  cat /etc/issue
  Red Hat Enterprise Linux Server release 5.8 (Tikanga)
  Kernel \r on an \m

  
  But in another setup, we are trying on a different machine having RHEL 5.9 
having higher kernel version but it still gives below error
  kvm does not support KVM_CAP_USER_MEMORY Please upgrade to at least kernel 
2.6.29 or recent kvm-kmod (see http://sourceforge.net/projects/kvm).
  failed to initialize KVM: Invalid argument No accelerator found!

  
  I don’t know if the qemu version have compatibility issues with redhat 5.9 
version –  need someone to check if the qemu can run on redhat 5.9 64 bit or 
not ?
