[Qemu-devel] [Bug 1037675] Re: Guest Kernel Panic if using "-cpu host" in qemu-kvm 1.1.1

[Michael Tokarev]

Correcting myself (comment #2):

> And forth, gentoo is very well known for breaking qemu-kvm by their
"hardened" patches. Disable the hardening and retry.

I mean the (host) KERNEL hardering, not qemu-kvm userspace hardering
there.  Sorry for any potential confusion.
