Xen: Enable livepatch
I’ve gone through the Xen live patch documentation.
It’s available https://wiki.xenproject.org/wiki/LivePatch
This stuff isn’t easy for sure but before you even can get started trying, you need to have it enabled.
Could we in future versions please build Xen with CONFIG_LIVEPATCH=y set?
People can then later decide if they’ll use it or not.
