I am running a CentOS 7 vm under FreeBSD, and it works very well now, with KDE installed from DVD iso.
But there’s a couple of things missing, which happens only with CentOS
1) Despite clipboard sharing enabled, copy-paste just does not work between host and guest
2) Mouse integration does not work. So I have to repeatedly capture mouse manually both in the host and in the guest.
If anyone could provide me tips how to tweak the above, it shall help me a lot.
