KVM and PaX

[evilangel]

Hey all,

I am wondering of using a CPU with AMD-V feature to run KVM.
In such a case, are my guest OS able to use the NX bit of the CPU, or is it limited to the host OS ?

Thanks

it always depends on whether the hypervisor makes the NX bit available to guest kernels or not. iirc, KVM does.
