xen-hypervisor-4.8-amd64 - Transitional package for upgrade

The hypervisor is the "core" for XEN itself. It gets booted by the boot loader and controls cpu and memory, sharing them between your administrative domain (Domain 0) and the virtual guest systems.
In order to boot a XEN system along with this package you also need a kernel specifically crafted to work as the Domain 0, mediating hardware access for XEN itself.

  • Security fixes from upstream XSAs:

    XSA-252 CVE-2018-7540
    XSA-255 CVE-2018-7541
    XSA-256 CVE-2018-7542

    The upstream BTI changes from XSA-254 (Spectre v2 mitigation) are *not* included. They are currently failing in upstream CI.
  • init scripts: Do not kill per-domain qemu processes. Closes:#879751.
  • Install Meltdown READMEs on all architectures. Closes:#890488.
  • Ship xen-diag (by cherry-picking the appropriate commits from upstream). This can help with diagnosis of #880554.
