[pve-devel] [PATCH-SERIES qemu-server/manager/docs v2 0/3] close #5291: support disabling KSM for specific VMs

[Fiona Ebner]

Changes in v2:
* Rebase on current master.
* I did not include Friedrich's T-b because it has been 9 months and
  there might've been changes to affect the result in
  kernel/QEMU/qemu-server/etc. (doesn't seem to be the case from my
  testing before sending the v2, but still didn't want to claim
  somebody else tested this, when it's been this long)

v1: https://lore.proxmox.com/pve-devel/20250217150444.142182-1-f.ebner@proxmox.com/

KSM exposes a guest's virtual memory to side-channel attacks. Add a VM
configuration option to disable KSM for specific VMs that need to be
protected against such attacks. This makes it possible to still
benefit from KSM for other processes on the host rather than needing
to turn of KSM completely.
