Same as francisod says virt-manager > view > details > add hardware > file system > select folder as source > select folder name for destination > finish

Source: is the local path you want to share. eg. /tmp
Target is a mount tag for the kvm client. eg. "9p-shared"

When your client is running you can mount "9p-shared" like this:

mkdir /mnt/9p-shared
mount -t 9p -o trans=virtio 9p-shared /mnt/9p-shared

Beware that this is only solves part of the problem. You also need to figure out how file/directory permissions are handled, but this page should help:

With the above, I can see files and read some of them but no write access. I tested this on Fedora 17 alpha host with a Fedora 16 virtual machine.

Thanks for your answer René. I didn't know it has to be mounted manually, I thought it was similar to VirtualBox. But when I try to mount I got an error about 9p: mount: unknown filesystem type '9p'. Any idea?

My host is Fedora 16 and the guest is Fedora 17, they are not so old... ok, I will have to figure out what is happening... thanks.

On RHEL 6.4 I'm getting the same problem as @skytux. I tried modprobing 9pnet_virtio, but no luck. Digging further.

It seems 9pnet_virtio is just the transport layer and a 9p module is required .. which is not in the standard kernel package. I wonder why 9pnet_virtio is there when it cannot do anything on its own.

I'm just not sure of the "target/destination folder" part. Not sure what should be put in there.

I sould have explained that I also tried that, but didn't know how to set target/destination, and without that doesn't work. I googled with no luck.
