pub const GUEST_VA_BASE_DEFAULT: u64 = 0x5000_0000_0000;Expand description
Base VA at which the guest’s entire memory range is mapped. Both the host (via mmap of snapshot/scratch regions) and the guest (via its page table) use this as the anchor. Configurable via JAR_GUEST_VA_BASE env var (hex string, with or without 0x prefix); default chosen to sit in the practically-never-touched mid-range band of x86_64 user VA space.
