3 NetBSD Virtualization Roadmap
4 =============================
5
6 This is a small roadmap document, and deals with the virtualization
7 side of the operating system.
8
9 Features that will be in 6.0:
10 1. NetBSD/usermode
11 5. Xen domU migration, suspend and resume
12
13 Features which may make future releases:
14 2. virtualization jails via secmodel
15 3. iSCSI booting
16 4. iSCSI device cloning
17
18 We'll continue to update this roadmap as features and dates get firmed up.

21 Some explanations
22 =================

24 1. NetBSD/usermode
25 ------------------
26
27 NetBSD/usermode is a port of NetBSD to a POSIX-compatible user-space,
28 with the intention that it should be possible to run the usermode
29 version of NetBSD on any POSIX-compatible operating system. This code
30 has been committed to the repository by jmcneill, and updated by reinoud
31 and jmcneill. usermode can now boot up to X11, can use a vnc console,
32 and is under active development now. This is most definitely in 6.0.

34 Responsible: jmcneill, reinoud
35
36 2. Virtualization Jails via secmodel
37 ------------------------------------
38
39 One novel way of creating jails for virtualization is to use a new
40 secmodel (part of the kauth framework), to isolate processes into
41 jail-based virtual machines. This is the basis of a paper given by
42 bad@ at AsiaBSDcon in March 2008. This will not make 6.0
43
44 Responsible: bad
45
46 3. iSCSI booting
47 ----------------
48
49 In order to make Xen domains migration-friendly, the storage that the
50 domain uses must be based on some form of network-centric storage, either
51 NFS, or a SAN or IP-SAN. For IP-SANs, iSCSI booting will be used. This
52 is dependent on the in-kernel iSCSI initiator project completing. This will not make 6.0
53
54 Responsible: agc
55
56 4. iSCSI device cloning
57 -----------------------
58
59 To minimise the storage requirements for multiple domU booting, using
60 a standard root filesystem or block device for the domU is required, along
61 with some form of copy-on-write mechanism to preserve any modifications
62 that are made. This will not make 6.0
63
64 Responsible: agc
65
66 5. Xen domU migration, suspend and resume
67 -----------------------------------------
68
69 Xen domU migration is where a domU domain is moved from one dom0 to
70 another dom0 on the same vlan (to avoid networking problems, the
71 virtual arp address migrates with the domU itself). jym has committed
72 this code, and it will be in 6.0
