[virtualization-kit (virt-kit)]

Wouldn't it be nice to have all the virtualization/emulation software in one kit instead it being all over the place?
It would make testing and deploying virtualization technologies much easier.
Most of the virtualization software is in nokit. LXC and LXD are in core-kit.
Some libvirt python bindings are in python-kit, and virtualbox guest additions are in xorg-kit.

virtualzation pkgs:
app-emulation/libvirt::nokit
app-emulation/qemu::nokit
app-emulation/lxc::core-kit
app-emulation/lxd::core-kit
app-emulation/virtualbox::nokit
app-emulation/virtualbox-bin::nokit
app-emulation/xen::nokit

virtualization tools:
app-emulation/virt-manager::nokit
app-emulation/virt-viewer::nokit
app-emulation/virtio-win::nokit
app-emulation/virtualbox-guest-additions::xorg-kit
app-emulation/open-vm-tools::nokit
dev-python/libvirt-python::python-kit

cloud related virtualization software:
app-emulation/docker::nokit
app-emulation/cloud-init::nokit
app-emulation/containerd::nokit

hard emulators:
app-emulation/bochs::nokit
app-emulation/armv8-fast-model::nokit
app-emulation/edumips64::nokit
app-emulation/vmips::nokit

I'm sure I forgot many packages, the open-vz kernel sources, probably more emulators, and more stuff related to docker,
but this is just an idea how to consolidate the virtualization packages into one kit.

[Getting Rid of Forums and Moving to Reddit?]

Funny thing is, that I wasn't aware that Funtoo is on Redit! I think the best thing would be to keep both, our Forums & Reddit.

just my 2 cents.

[Help w/ networking for KVM guests]

Just to clarify things, for bridge to work, you need two configs (tap & bridge)

 

config for tap should look like this:

file: /etc/conf.d/net.tap0

template="tap"

 

config for br0 should look like this:

file: /etc/conf.d/net.br0

template="bridge"
ipaddr="192.168.2.1/24"
slaves="net.tap0"
stp="on"
forwarding="1"

 

If these two configs work, then add stuff like domains, nameservers, routes, mtu's etc...

also make sure, that you actually have IP forwarding enabled on your system (echo 1 > /proc/sys/net/ipv4/ip_forward)

 

Actual network templates are located in /etc/netif.d/

If you don't like them, you can create custom ones!

[What kind of hardware do you have and how do you use it?]

CPU: i7 6700k@stock

RAM: 64GB Kingston HyperX Fury

MB: Gigabyte Z170x Gaming7

GPU: Sapphire Radeon RX480 8GB Nitro

SSD: Samsung 850 EVO 500GB

HDD: 6x Seagate 3TB in RAID6

Sound: Creative SoundBlaster X-Fi

Case: Fractal Design Define XL R2

 

This is essentially my home workstation. I use it for coding, testing, virtualization (KVM & LXC) and gaming.

It's fast and everything feels really snappy.

Everything works with open-source drivers on current v4.9 kernel.

Radeon RX480 uses new open-source AMDGPU drivers (in kernel since v4.7). It's extremly fast and stable (at least compared with other GPU's that I've seen on Linux)

 

I also have Thinkpad E540, that I use when I'm not home.

[Post your make.conf]

This is make.conf used on my Skylake system (i7 6700k)

 

You can use "app-portage/cpuid2cpuflags" to adjust CPU_FLAGS_X86 for other systems (run cpuinfo2cpuflags-x86)

[Safe way to access linux file server from a linux laptop]

You can use "net-fs/sshfs" to safely connect to your server.

All you need is publicly accessible IP on your server & opened SSH port

 

syntax is something like this:

sshfs username@host:/   local_directory/

(local_directory is a directory in your home-dir)

 

You can also try "net-misc/unison" for two-way synchronization, or unison + rsync, once you have remote dir mounted.

 

If you need single software that does it all try BORG (e.g. app-backup/borgbackup), but this is usually only used on servers to make differential backups.

[llvm-gcc + systemd ?]

I dont care much about gcc vs clang (actually I think something good might come out of clang),

but I care that funtoo stays away from systemd, its the ultimate bloatware (Poetteringware) ;-)
