3 NetBSD Virtualization Roadmap
4 =============================
6 This is a small roadmap document, and deals with the virtualization
7 side of the operating system.
10 2. virtualization jails via secmodel
12 4. iSCSI device cloning
13 5. Xen domU migration, suspend and resume
14 6. Xen balloon driver support
16 We currently expect to branch 6.0 in the March 2010 timeframe, with a view
17 to a 6.0 release later in 2010.
19 We'll continue to update this roadmap as features and dates get firmed up.
28 NetBSD/usermode is an port of NetBSD to a POSIX-compatible user-space,
29 with the intention that it should be possible to run the usermode
30 version of NetBSD on any POSIX-compatible operating system. This code
31 has been committed to the repository, but more work is needed.
35 2. Virtualization Jails via secmodel
36 ------------------------------------
38 One novel way of creating jails for virtualization is to use a new
39 secmodel (part of the kauth framework), to isolate processes into
40 jail-based virtual machines. This is the basis of a paper given by
41 bad@ at AsiaBSDcon in March 2008.
48 In order to make Xen domains migration-friendly, the storage that the
49 domain uses must be based on some form of network-centric storage, either
50 NFS, or a SAN or IP-SAN. For IP-SANs, iSCSI booting will be used. This
51 is dependent on the in-kernel iSCSI initiator project completing.
55 4. iSCSI device cloning
56 -----------------------
58 To minimise the storage requirements for multiple domU booting, using
59 a standard root filesystem or block device for the domU is required, along
60 with some form of copy-on-write mechanism to preserve any modifications
65 5. Xen domU migration, suspend and resume
66 -----------------------------------------
68 Xen domU migration is where a domU domain is moved from one dom0 to
69 another dom0 on the same vlan (to avoid networking problems, the
70 virtual arp address migrates with the domU itself). jym is actively
71 working on this, and preliminary results are good.
73 Responsible: jym, bouyer
75 6. Xen balloon driver support
76 -----------------------------
78 The balloon driver allows more memory to be added to a running Xen domU
79 instance; this allows extra memory to be used by the domU for resource
80 peak needs. cherry has made a preliminary balloon driver - some testing
81 is needed before it can be committed.
