Hello Experts,
I am using CentOS 6.5. I am getting an issue with libguestfs (qemu-kvm)

 #  /usr/libexec/qemu-kvm -nographic -machine accel=kvm:tcg -device \?

 open /dev/kvm: No such file or directory

Check your kernel and dev dir.

# lsmod | grep kvm
# Output should look like this, execpt for the numbers and
#   intel may be amd:
kvm_intel             134469  19
kvm                   392084  1 kvm_intel
# ls -l /dev/kvm
# Output should look like this, but the date is not important:
crw-rw---T 1 root kvm 10, 232 Sep 18  2014 /dev/kvm

I saw this issue listed in libguestfs faq "http://libguestfs.org/guestfs-faq.1.html"; and executed "setsebool -P virt_use_execmem=on" as a solution but that also did not help. I confirmed this solution with libguestfs mailing list. They asked me to to write to you. Could you please help me.

Thanks a lot in advance,
