There is not a single place in the source code where you can see a
connection between feature availability and cluster level. The best way is
to take a look at relevant RFE in Bugzilla, which introduces a new cluster
level and there take a look at dependent RFEs/bugs:
*1933974* <https://bugzilla.redhat.com/show_bug.cgi?id=1933974> - [RFE]
Introduce Datacenter and cluster level 4.6
*1669178* <https://bugzilla.redhat.com/show_bug.cgi?id=1669178> - [RFE]
Q35 SecureBoot - Add ability to preserve variable store certificates.
*1688177* <https://bugzilla.redhat.com/show_bug.cgi?id=1688177> - [RFE]
[SR-IOV] [Tech Preview RHV 4.4.6] Migration should not require downtime as
of today
*1906074* <https://bugzilla.redhat.com/show_bug.cgi?id=1906074> - [RFE]
Support disks copy between regular and managed block storage domains
*1927718* <https://bugzilla.redhat.com/show_bug.cgi?id=1927718> - [RFE]
Provide Reset option for VMs
*1950752* <https://bugzilla.redhat.com/show_bug.cgi?id=1950752> -
[RFE][CBT]
redefine only the checkpoint that the backup is taken from and not the
entire chain
*1821199* <https://bugzilla.redhat.com/show_bug.cgi?id=1821199> - HP VM
fails to migrate between identical hosts (the same cpu flags) not
supporting TSC.
*1834250* <https://bugzilla.redhat.com/show_bug.cgi?id=1834250> - CPU
hotplug on UEFI VM causes VM reboot
*1892800* <https://bugzilla.redhat.com/show_bug.cgi?id=1892800> - NVDIMM:
VM hangs in wait for launch for more than 7 minutes before VM is up.
*1936163* <https://bugzilla.redhat.com/show_bug.cgi?id=1936163> - Enable
bochs-display for UEFI guests by default
*1936164* <https://bugzilla.redhat.com/show_bug.cgi?id=1936164> - Enable
KVM Software TPM by default
*1877675* <https://bugzilla.redhat.com/show_bug.cgi?id=1877675> - [RFE]
Introduce Datacenter and cluster level 4.5
*1725166* <https://bugzilla.redhat.com/show_bug.cgi?id=1725166> - [RFE]
Private VLAN / port isolation
*1745024* <https://bugzilla.redhat.com/show_bug.cgi?id=1745024> - [RFE]
Enabling Icelake new NIs - RHV
*1836661* <https://bugzilla.redhat.com/show_bug.cgi?id=1836661> - [RFE]
GET diskattachments for a VM using qemu-guest-agent is missing a
logical_name for disks without monted file-system
*1814565* <https://bugzilla.redhat.com/show_bug.cgi?id=1814565> - Report
disk.usage for VMs with RHEL 8 guests
*1852718* <https://bugzilla.redhat.com/show_bug.cgi?id=1852718> - vGPU:
VM failed to run with mdev_type instance
*1853194* <https://bugzilla.redhat.com/show_bug.cgi?id=1853194> - VM
with disk on iscsi on environment with SELinux enforced fails to start on
host - Exit message: Wake up from hibernation failed:internal error: child
reported (status=125): unable to set security context
*1876605* <https://bugzilla.redhat.com/show_bug.cgi?id=1876605> - VM
with scsi hostdev (scsi_generic custom property) fails on start:'node-name
too long for qemu'
Also not all features depend on cluster level, so there can be new features
introduced in some particular oVirt version which will start working for
all existing cluster levels.
That's why every new feature is announced in the release notes for a
particular oVirt version.
