-
- whatever happens to be earlier.
Additional/Updated Modules:
---------------
depends on latest kernel and header package within a certain kernel series,
-e.g., pve-kernel-5.11 / pve-headers-5.11
+e.g., pve-kernel-4.15 / pve-headers-4.15
git clone git://git.proxmox.com/git/pve-kernel-meta.git
CONFIG_BLK_DEV_RBD=m
- enable IBM JFS file system as module
- requested by users (bug #64)

+ net.bridge.bridge-nf-call-iptables is an unknown key
- enable CONFIG_DEFAULT_SECURITY_APPARMOR
+
We need this for lxc
- set CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y
+
because if not set, it can give some dynamic memory or cpu frequencies
change, and vms can crash (mainly windows guest).

- use 'deadline' as default scheduler
- This is the suggested setting for KVM. We also measure bad fsync performance with ext4 and cfq.

- disable CONFIG_INPUT_EVBUG
- Module evbug is not blacklisted on debian, so we simply disable it to avoid
- key-event logs (which is a big security problem)

- enable CONFIG_MODVERSIONS (needed for ABI tracking)
- switch default UNWINDER to FRAME_POINTER

the recently introduced ORC_UNWINDER is not 100% stable yet, especially in combination with ZFS
- enable CONFIG_PAGE_TABLE_ISOLATION (Meltdown mitigation)
