STRUCT MSHV_CREATE_PARTITION(9)

💅 struct mshv_create_partition(9) 💅

okay bestie so we're in the Kernel API Manual today, and this page is literally about struct mshv_create_partition — yes it's a struct, yes it's got two __u64 fields, yes we're gonna get through it together 🫶

---

✨ NAME ✨

struct mshv_create_partition — the arguments you hand over for MSHV_CREATE_PARTITION, no cap 💫

---

🎀 SYNOPSIS 🎀

struct mshv_create_partition {
    __u64 pt_flags;
    __u64 pt_isolation;
 };

look at her. two fields. flawless. iconic. 💅

---

🌸 Members 🌸

• pt_flags — a bitmask of 1 << MSHV_PT_BIT_* ✨ (it's giving "pick your bits, bestie")
• pt_isolation — an MSHV_PT_ISOLATION_* value 💖

---

🦋 Description 🦋

okay so this is the initial/v1 version, kept around purely for backward compatibility 🔥 — like that one friend who's still on the old group chat and honestly? we respect her.

It returns a file descriptor that acts as a handle to a guest partition 💫. and here's the thing — at this point the partition isn't initialized in the hypervisor yet. she's just vibing. not yet setup. 🌈

Some operations must be done while she's in this state, for example setting the so-called "early" partition properties 🌸 (yes, early. get there before everyone else. main character energy 👑).

After that, the partition can then be initialized with MSHV_INITIALIZE_PARTITION ⭐

💀 reminder for the girlies: not initialized yet ≠ ready to go. do the early stuff first, then initialize. periodt.
