Subject: [PATCH] docs: document correct cpu shares limits with both cgroups v1
|
|
|
735c6b |
and v2
|
|
|
735c6b |
|
|
|
735c6b |
The limits are different with cgroups v1 and v2 but our XML
|
|
|
735c6b |
documentation and virsh manpage mentioned only cgroups v1 limits without
|
|
|
735c6b |
explicitly saying it only applies to cgroups v1.
