I am running a VM on a Linux host using qemu+kvm and libvirt, the guest system is CentOS 7. I wish to share a folder between the two such that host:/some/dir becomes accessible as guest:/some/other/dir.I wish to minimise effort and cannot re-compile the kernel on either side.  I experimented with plan9 but cannot get it to run (the p9 dkms module won't compile on the CentOS 7 guest).There must be a better way?  Performance is secondary as it does not work at all right now.
How to share a folder in libvirt+qemu/kvm with Linux guest and Linux host?
kvm;qemu;libvirt;plan9
