(yay, progress!) - ZFS was updated to be based on FreeBSD's version, and "works", but more stabilization, optimization, and updating is always needed. - NVME's been supported for several major releases now, but more optimization work is always needed. - Our scheduler is now topology-aware (yay, progress!) - Mention aarch64 support in nvmm. @ text @$NetBSD: virtualization,v 1.7 2024/09/08 09:36:45 rillig Exp $ NetBSD Virtualization Roadmap ============================= This is a small roadmap document, and deals with the virtualization side of the operating system. Features that will be in 6.0: 1. NetBSD/usermode 5. Xen domU migration, suspend and resume Features which may make future releases: 2. virtualization jails via secmodel 3. iSCSI booting 4. iSCSI device cloning 5. Arm64 (aarch64) support in NVMM We'll continue to update this roadmap as features and dates get firmed up. Some explanations ================= 1. NetBSD/usermode ------------------ NetBSD/usermode is a 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. This code has been committed to the repository by jmcneill, and updated by reinoud and jmcneill. usermode can now boot up to X11, can use a vnc console, and is under active development now. This is most definitely in 6.0. Responsible: jmcneill, reinoud 2. 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 given by bad@@ at AsiaBSDcon in March 2008. This will not make 6.0 Responsible: bad 3. 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. This is dependent on the in-kernel iSCSI initiator project completing. This will not make 6.0 Responsible: agc 4. 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. This will not make 6.0 Responsible: agc 5. 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). jym has committed this code, and it will be in 6.0 Responsible: jym, bouyer 6. Arm64 (aarch64) support in NVMM ---------------------------------- Initial work was done on porting nvmm(4) to ARMv8.0 by Ryo Shimizu and presented at 2023 AsiaBSDCon. Due to his very sad passing, the port is now without a maintainer. It would be amazing if someone picked up and finished this work. https://github.com/IIJ-NetBSD/netbsd-src/compare/master...ryo:netbsd-src:wip/aarch64_el2 Alistair Crooks Sat Jan 14 11:38:50 PST 2012 @ 1.7 log @fix a/an grammar in obvious cases @ text @d1 1 a1 1 $NetBSD: virtualization,v 1.6 2019/06/17 18:22:41 sevan Exp $ d17 1 d77 10 @ 1.6 log @balloon(4) is in @ text @d1 1 a1 1 $NetBSD: virtualization,v 1.5 2012/01/15 02:45:42 agc Exp $ d27 1 a27 1 NetBSD/usermode is an port of NetBSD to a POSIX-compatible user-space, @ 1.6.12.1 log @Sync with HEAD @ text @d1 1 a1 1 $NetBSD: virtualization,v 1.8 2025/05/19 18:02:53 nia Exp $ a16 1 5.

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. Responsible: jmcneill 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). Responsible: bouyer 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.

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.
