This causes an artifical pressure using the vmmemctl driver on memory usage on the virtual guest. As VyOS by default does not have a swap file, this vmmemctl pressure is unable to
force processes to move in memory data to the paging file, and blindly consumes memory forcing the virtual guest into a low memory state with no way to escape. The balloon can expand to 65% of
-guest allocated memory, so a VyOS guest running >35% of memory usage, can encoutner an out of memory situation, and trigger the kernel oom_kill process. At this point a weighted
+guest allocated memory, so a VyOS guest running >35% of memory usage, can encounter an out of memory situation, and trigger the kernel oom_kill process. At this point a weighted
lottery favouring memory hungry processes will be run with the unlucky winner being terminated by the kernel.
It is advised that VyOS routers are configured in a resource group with adequate memory reservations so that ballooning is not inflicted on virtual VyOS guests.
