Hi,
I have a setup with multiple virtual machines (VMs), each with a saved
state. All VMs share the same parent, which is located on a shared drive.
Whenever I restore any VM using virsh restore, the parent is dropped from
the system cache, causing all data to be downloaded from the shared drive
again. This results in unnecessary network traffic, even though the parent
changes very rarely. However, if I create a child from the parent and
call virsh
create to create a new VM, the parent is never dropped from the system
cache.
Is this expected behavior? Should the parent be retained in the system
cache during a virsh restore operation? Are there any configurations or
settings that can prevent the parent from being dropped from the cache?
thanks
