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

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

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

35
362. Virtualization Jails via secmodel
37------------------------------------
38
39One novel way of creating jails for virtualization is to use a new
40secmodel (part of the kauth framework), to isolate processes into
41jail-based virtual machines. This is the basis of a paper given by
42bad@ at AsiaBSDcon in March 2008. This will not make 6.0

44Responsible: bad

463. iSCSI booting
47----------------
48
49In order to make Xen domains migration-friendly, the storage that the
50domain uses must be based on some form of network-centric storage, either
51NFS, or a SAN or IP-SAN. For IP-SANs, iSCSI booting will be used. This
52is dependent on the in-kernel iSCSI initiator project completing. This will not make 6.0
53
54Responsible: agc
55
564. iSCSI device cloning
57-----------------------
58
59To minimise the storage requirements for multiple domU booting, using
60a standard root filesystem or block device for the domU is required, along
61with some form of copy-on-write mechanism to preserve any modifications
62that are made. This will not make 6.0

65
665. Xen domU migration, suspend and resume
67-----------------------------------------
68
69Xen domU migration is where a domU domain is moved from one dom0 to
70another dom0 on the same vlan (to avoid networking problems, the
71virtual arp address migrates with the domU itself). jym has committed
72this code, and it will be in 6.0
