I know a few of you use/used Qemu/KVM; I'm trying to kick the VMware
habbit here, but it's not turning out as easy as I thought it would be.
Besides som minor issues with the storage that I finally figured out, I
have great trouble with the network side. I simply want a bridged
network so the VM uses the same DHCP server as the host does. However,
the configuration for networking doesn't seem to be active in the very
When using the "Virtual Network Editor" I get three networks defined:
vmnet0 (bridged), vmnet1 (host-only) and vmnet8 (NAT). All very straight
forward and fairly easy to figure out. However, none of them are active
for VMs to use. Instead "brctl show" returns virbr0 which is enabled in
a configuration else-where. So how to enable the kvm-defined networks?
When I try to assign network devices to a kvm, all I see is the NAT -
everything else says the bridge is disabled. Since I don't even see the
network names defined with kvm, I'm sure somekind of configuration
points to the "wrong" place that ignores what the gui think is right -
Btw. the package qemu-kvm is empty on fedora 12??
When we did KVM at our fredlug meeting back in October (I think it was)
that was my biggest issue and actually never got resolved. So I wonder
if the F12 implementation somehow lacks the setup to be used in the way
I want, and I fear I may have to become a KVM master to just get a VM
using a bridge :( Please tell me that isn't the case; at least it's one
of the reasons vmware may keep existing as the prime tool since this
stuff simply just "works" out of the box (well, once you have figured
out how to install it on the box that is - at least kvm/qemu is way easy
