Struct Balloon

pub struct Balloon {
    pub amount_mib: u32,
    pub deflate_on_oom: Option<bool>,
    pub stats_polling_interval_s: Option<u32>,
}

Represents a memory balloon device that can dynamically adjust guest memory size. This device allows for memory overcommitment by reclaiming unused memory from the guest and making it available to the host or other guests. It’s particularly useful in environments where memory resources need to be managed efficiently across multiple VMs.

Fields

amount_mib: u32

Target balloon size in MiB

deflate_on_oom: Option<bool>

Whether the balloon should deflate when the guest has memory pressure

stats_polling_interval_s: Option<u32>

Interval in seconds between refreshing statistics. A non-zero value will enable the statistics. Defaults to 0
