When trying to use vhost I get the error "vhost-net requested but could
not be initialized". The only thing I have been able to find about this
problem relates to SElinux being turned off which mine is disabled and
permissive. Just wondering if there were any other thoughts on this
error? Am I correct that it should work with the .35.4 kernel and
version 12.5 KVM?
KVM Host OS: Fedora 12 x86_64
KVM Guest OS Tiny Core Linux 2.6.33.3 kernel
Host kernel 2.6.35.4 and qemu-system-x86_64 12.5 compiled from from
qemu-kvm repo.
Starting with:
modprobe kvm
modprobe kvm_intel
modprobe tun
echo -e "Setting up bridge device br0" "\r"
brctl addbr br0
ifconfig br0 192.168.100.254 netmask 255.255.255.0 up
brctl addif br0 eth7
ifconfig eth7 down
ifconfig eth7 0.0.0.0
for ((i=0; i < NUM_OF_DEVICES ; i++)); do
