NetBSD Virtualization Roadmap
|
|
=============================
|
|
|
|
This is a small roadmap document, and deals with the virtualization
|
|
side of the operating system.
|
|
|
|
NetBSD 5.0 will ship with the following virtualization elements in
|
|
place:
|
|
|
|
1. Xen 3 Dom0 [i386/amd64]
|
|
2. Xen 3 DomU [i386/amd64]
|
|
3. Xen 3 PAE DomU [i386]
|
|
|
|
The following elements and projects are pencilled in for 5.0, but
|
|
please do not rely on them being there.
|
|
|
|
4. NetBSD/usermode
|
|
5. virtualization jails via secmodel
|
|
|
|
The following projects are expected to be included in NetBSD 6.0
|
|
|
|
6. iSCSI booting
|
|
7. iSCSI device cloning
|
|
8. Xen domU migration, suspend and resume
|
|
9. Xen balloon driver support
|
|
|
|
We expect to branch for the 5.0 release in April or May 2008, which would
|
|
put a NetBSD 5.0 Release date in Q4 2008. An annual release cycle would
|
|
thus mean that 6.0 would be branched in April or May 2009.
|
|
|
|
Pictorially, this looks like:
|

Some explanations
|
|
=================
|
|
|
|
4. NetBSD/usermode
|
|
------------------
|
|
|
|
NetBSD/usermode is an port of NetBSD to a POSIX-compatible user-space, with
|
|
the intention that it should be possible to run the usermode version of
|
|
NetBSD on any POSIX-compatible operating system.

5. Virtualization Jails via secmodel
|
|
------------------------------------
|
|
|
|
One novel way of creating jails for virtualization is to use a new
|
|
secmodel (part of the kauth framework), to isolate processes into
|
|
jail-based virtual machines. This is the basis of a paper to appear
|
|
in the AsiaBSDcon proceedings in March 2008.
|
|
|
|
Responsible: bad

|
|
|
6. iSCSI booting
|
|
----------------
|
|
|
|
In order to make Xen domains migration-friendly, the storage that the
|
|
domain uses must be based on some form of network-centric storage, either
|
|
NFS, or a SAN or IP-SAN. For IP-SANs, iSCSI booting will be used.
|
|
|
|
Responsible: agc
|
|
|
|
7. iSCSI device cloning
|
|
-----------------------
|
|
|
|
To minimise the storage requirements for multiple domU booting, using
|
|
a standard root filesystem or block device for the domU is required, along
|
|
with some form of copy-on-write mechanism to preserve any modifications
|
|
that are made.
|
|
|
|
Responsible: agc
|
|
|
|
8. Xen domU migration, suspend and resume
|
|
-----------------------------------------
|
|
|
|
Xen domU migration is where a domU domain is moved from one dom0 to
|
|
another dom0 on the same vlan (to avoid networking problems, the
|
|
virtual arp address migrates with the domU itself).
|
|
|
|

|
|
|
9. Xen balloon driver support
|
|
-----------------------------
|
|
|
|
The balloon driver allows more memory to be added to a running Xen domU
|
|
instance; this allows extra memory to be used by the domU for resource
|
|
peak needs.
