STRUCT ACRN_VM_CREATION(9)

✨ NAME ✨

okay so bestie, welcome to the Kernel API Manual page for struct acrn_vm_creation — it's literally Info to create a User VM, and it's giving main-character hypervisor energy 👑. We're going through every single field because details are the whole vibe, no cap 💅.

🦋 SYNOPSIS 🦋

here's the struct in all its glory:

struct acrn_vm_creation {
    __u16 vmid;
    __u16 reserved0;
    __u16 vcpu_num;
    __u16 reserved1;
    __u8 uuid[16];
    __u64 vm_flag;
    __u64 ioreq_buf;
    __u64 cpu_affinity;
};

🎀 Members 🎀

• vmid — User VM ID returned from the hypervisor 🫶.
• reserved0 — Reserved, and it must be 0 — do not be quirky with this one, bestie.
• vcpu_num — Number of vCPU in the VM. Return from hypervisor. ✨
• reserved1 — Reserved, and it must be 0 — same vibe check as reserved0.
• uuid — Empty space never to be used again (used to be UUID of the VM) 💀. It's giving retired icon energy.
• vm_flag — Flag of the VM creating. Pass to hypervisor directly 🔥.
• ioreq_buf — Service VM GPA of I/O request buffer. Pass to hypervisor directly 🎀.
• cpu_affinity — CPU affinity of the VM. Pass to hypervisor directly. It's a bitmap which indicates CPUs used by the VM 🧚.
