NetBSD/usermode 11 1.5 agc 5. Xen domU migration, suspend and resume 12 1.5 agc 13 1.5 agc Features which may make future releases: 14 1.4 agc 2. virtualization jails via secmodel 15 1.4 agc 3. iSCSI booting 16 1.4 agc 4. iSCSI device cloning 17 1.1 agc 18 1.1 agc We'll continue to update this roadmap as features and dates get firmed up. 19 1.1 agc 20 1.1 agc 21 1.1 agc Some explanations 22 1.1 agc ================= 23 1.1 agc 24 1.4 agc 1. NetBSD/usermode 25 1.1 agc ------------------ 26 1.1 agc 27 1.7 rillig NetBSD/usermode is a port of NetBSD to a POSIX-compatible user-space, 28 1.4 agc with the intention that it should be possible to run the usermode 29 1.4 agc version of NetBSD on any POSIX-compatible operating system. This code 30 1.5 agc has been committed to the repository by jmcneill, and updated by reinoud 31 1.5 agc and jmcneill. usermode can now boot up to X11, can use a vnc console, 32 1.5 agc and is under active development now. This is most definitely in 6.0. 33 1.1 agc 34 1.5 agc Responsible: jmcneill, reinoud 35 1.1 agc 36 1.4 agc 2. Virtualization Jails via secmodel 37 1.1 agc ------------------------------------ 38 1.1 agc 39 1.1 agc One novel way of creating jails for virtualization is to use a new 40 1.1 agc secmodel (part of the kauth framework), to isolate processes into 41 1.4 agc jail-based virtual machines. This is the basis of a paper given by 42 1.5 agc bad@ at AsiaBSDcon in March 2008. This will not make 6.0 43 1.1 agc 44 1.1 agc Responsible: bad 45 1.1 agc 46 1.4 agc 3. iSCSI booting 47 1.1 agc ---------------- 48 1.1 agc 49 1.1 agc In order to make Xen domains migration-friendly, the storage that the 50 1.1 agc domain uses must be based on some form of network-centric storage, either 51 1.4 agc NFS, or a SAN or IP-SAN. For IP-SANs, iSCSI booting will be used. This 52 1.5 agc is dependent on the in-kernel iSCSI initiator project completing. This will not make 6.0 53 1.1 agc 54 1.1 agc Responsible: agc 55 1.1 agc 56 1.4 agc 4. iSCSI device cloning 57 1.1 agc ----------------------- 58 1.1 agc 59 1.1 agc To minimise the storage requirements for multiple domU booting, using 60 1.1 agc a standard root filesystem or block device for the domU is required, along 61 1.1 agc with some form of copy-on-write mechanism to preserve any modifications 62 1.5 agc that are made. This will not make 6.0 63 1.1 agc 64 1.1 agc Responsible: agc 65 1.1 agc 66 1.4 agc 5. Xen domU migration, suspend and resume 67 1.1 agc ----------------------------------------- 68 1.1 agc 69 1.1 agc Xen domU migration is where a domU domain is moved from one dom0 to 70 1.1 agc another dom0 on the same vlan (to avoid networking problems, the 71 1.5 agc virtual arp address migrates with the domU itself). jym has committed 72 1.5 agc this code, and it will be in 6.0 73 1.1 agc 74 1.4 agc Responsible: jym, bouyer 75 1.1 agc 76 1.1 agc Alistair Crooks 77 1.5 agc Sat Jan 14 11:38:50 PST 2012 78
