## Virtualization tool
https://docs.fedoraproject.org/en-US/Fedora/23/html/Virtualization_Getting_Started_Guide/sec-Other-Useful-tools.html
https://github.com/kvmtool/kvmtool kvmtool is a lightweight tool for hosting KVM guests. As a pure virtualization
tool it only supports guests using the same architecture, though it supports
running 32-bit guests on those 64-bit architectures that allow this.

### Qemu

### TPM
https://fossies.org/linux/qemu/docs/specs/tpm.rst
### Ideas from hackernews blog post (as used by Red Hat)
* Aggressively compile out unused features/devices.
* Confine each VM with separate SELinux contexts (sVirt).
* Run qemu as a special non-root user.
* Use seccomp to confine the system calls.
* Pass in pre-opened file descriptors to qemu, so qemu doesn't need to open files (helps with writing tightly confined SELinux policy).
* Run qemu in a cgroup.
* Run qemu-img with resource limits.
* Compile qemu with all hardening features enabled like RELRO, PIE, etc.
* Audit the code manually and with Coverity.
* Take security reports seriously and have a fast patching mechanism (you can effectively "live patch" qemu by migrating a VM off the old qemu and on to the new qemu).
Probably more that I've forgotten about ...

Additionally, in case you are using QEMU 4.0 (or higher) in combination with a Q35 chip, the flag ‘ioapic driver='kvm'‘ needs to be added in the features section (see excerpt marked blue).
