Thanks Intel (and maybe others)!

Very interesting Sascha, thank you for bringing this to my attention. Maybe my Haswell system (which is also affected) will suffice for 2018 :-P

The Spectre attacks appear to suck big-time. Regarding Meltdown, I hope AMD will soon have a Ryzen CPU with APU ready ...

Hi Jonas,

there is news about an Intel CPU hardware bug: https://www.reddit.com/r/sysadmin/comments/7nl8r0/intel_bug_incoming/

Fixes for that may decrease performance under certain workloads (especially virtualisation and IO heavy loads).

So maybe hold off that purchase for a bit longer until there is more information.

Regards, Sascha

    Dear everyone,

    Anything special to consider before buying hardware in January 2018?

    My aim is to run my Linux workstation and a single Windows 10
    gaming VM
    with a dedicated GPU assigned via VFIO. The only piece of hardware
    which
    is dead certain to be in the build is my newly purchased ASUS
    Strix GTX1070.

    It is an mini-itx build, in my A4-SFX v1 case, so I'm forced to
    choose a
    platform with an build-in GPU since since I can only fit a single
    dedicated graphics card.

    Does that mean Intel Kaby Lake these days? Anything special to note
    about the various 100- and 200-series chipsets?

    Maybe I should look for a motherboard with at least two USB
    controllers
    so one can be assigned to the VM, although I plan on using only a
    single
    set of mouse/keyboard (I have seen people assign usb devices or
    controllers on the fly, i.e. effectively switching mouse/keyboard
    between guest/host).

    Thank you for your input.

    / Jonas
