Kernel development virtualization options

Kernel development virtualization options

[Laurence Rochfort]

Hi all,

Thus far, I've been testing my kernel patches in a KVM vm with a full
distro installation, but it's pretty slow and cumbersome.

Valerie Aurora has a blog post on using User-mode Linux, and others
mention QEMU with an overlay filesystem and BusyBox.

What do people recommend for quick iterative development, with good
GDB integration?

Cheers,
Laurence.

Hmmm, weird, assuming your CPU had VT-x/AMD-V enabled, KVM should utilize
it and ran pretty fast. Could you check whether KVM use VT-x/AMD-V first?
