Message-Id: <1461426709-24094-1-git-send-email-andrey_utkin@fastmail.com> Date: Sat, 23 Apr 2016 18:51:49 +0300 From: Andrey Utkin <andrey_utkin@...tmail.com> To: linux-kernel@...r.kernel.org, x86@...nel.org Cc: Thomas Gleixner <tglx@...utronix.de>, Ingo Molnar <mingo@...hat.com>, "H. Peter Anvin" <hpa@...or.com>, Andrey Utkin <andrey_utkin@...tmail.com> Subject: [PATCH] Enhance kvmconfig This was tested only on Hetzner CX10 VPS. I don't know how recent KVM server stuff they use. Tests & reports from anybody else are appreciated. I guess some of added options may be not strictly necessary or make not that lot of sense as enabled by default, feel free to ask me to drop some and test how it works. Thanks. ---8<--- "make defconfig kvmconfig" is supposed to end up with usable kernel for KVM guest. In practice, it won't work for e.g. Hetzner VPS (KVM-based) unless you add these options.
