Subject Re: KVM evaluation
Date Mon, 02 Oct 2017 11:47:27 GMT
Hi,

we have Advanced zone, purely KVM, for last 3-5 years... no major KVM
related problems really.

- You preferably want qemu 2.5+/libvirt 1.3+  - i.e. Ubuntu 16.04 natively
(ACS4.9+), or Ubuntu 14.04 with OpenStack repo that provides these
binaries)  - simply because of auto-convergence, otherwise unable to nicely
live-migrate VMs that are "busy" (high enough RAM write/change rate, so VM
migration never finishes automatically - we are currently on Ubuntu 14.04
with Openstack virtualization repo, but plan to go native 16.04 soon...
- no special tweeks I believe, works just nice.
- We have tons of Windows VMs, so some experience running Windows VMs -
specifically, avoid running Windows 2008/Windows7 (or implement patch that
provides "Hyper-V Enlightenment for KVM" - we have it internally, just
never committed back unfortunately...)
- with Windows VMs, make sure you have proper virtio-enabled VM templates
and always use "Windows PV" as type of VM, etc.
- make sure you use Sandy Bridge as CPU model inside your agent.conf,
otherwise Windows 2016 will not boot at all.... etc.

Ping me if more info needed.

Cheers
