Xen 3 Dom0 [i386/amd64] 13 1.2.4.2 keiichi 2. Xen 3 DomU [i386/amd64] 14 1.2.4.2 keiichi 3. Xen 3 PAE DomU [i386] 15 1.2.4.2 keiichi 16 1.2.4.2 keiichi The following elements and projects are pencilled in for 5.0, but 17 1.2.4.2 keiichi please do not rely on them being there. 18 1.2.4.2 keiichi 19 1.2.4.2 keiichi 4. NetBSD/usermode 20 1.2.4.2 keiichi 5. virtualization jails via secmodel 21 1.2.4.2 keiichi 22 1.2.4.2 keiichi The following projects are expected to be included in NetBSD 6.0 23 1.2.4.2 keiichi 24 1.2.4.2 keiichi 6. iSCSI booting 25 1.2.4.2 keiichi 7. iSCSI device cloning 26 1.2.4.2 keiichi 8. Xen domU migration, suspend and resume 27 1.2.4.2 keiichi 9. Xen balloon driver support 28 1.2.4.2 keiichi 29 1.2.4.2 keiichi We expect to branch for the 5.0 release in April or May 2008, which would 30 1.2.4.2 keiichi put a NetBSD 5.0 Release date in Q4 2008. An annual release cycle would 31 1.2.4.2 keiichi thus mean that 6.0 would be branched in April or May 2009. 32 1.2.4.2 keiichi 33 1.2.4.2 keiichi Pictorially, this looks like: 34 1.2.4.2 keiichi 35 1.2.4.2 keiichi 2008 2009 36 1.2.4.2 keiichi Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Jan Feb Mar Apr May Jun Jul Aug 37 1.2.4.2 keiichi |===|===|===|===|===|===|===|===|===|===|===|===|===|===|===|===|===|===|===| 38 1.2.4.2 keiichi 39 1.2.4.2 keiichi | ------- 5.0 --------- | | ------- 6.0 40 1.2.4.2 keiichi branch release branch 41 1.2.4.2 keiichi 42 1.2.4.2 keiichi 1-3 4,5 6 7 8 9 43 1.2.4.2 keiichi 44 1.2.4.2 keiichi We'll continue to update this roadmap as features and dates get firmed up. 45 1.2.4.2 keiichi 46 1.2.4.2 keiichi 47 1.2.4.2 keiichi Some explanations 48 1.2.4.2 keiichi ================= 49 1.2.4.2 keiichi 50 1.2.4.2 keiichi 4. NetBSD/usermode 51 1.2.4.2 keiichi ------------------ 52 1.2.4.2 keiichi 53 1.2.4.2 keiichi NetBSD/usermode is an port of NetBSD to a POSIX-compatible user-space, with 54 1.2.4.2 keiichi the intention that it should be possible to run the usermode version of 55 1.2.4.2 keiichi NetBSD on any POSIX-compatible operating system. 56 1.2.4.2 keiichi 57 1.2.4.2 keiichi Responsible: jmcneill 58 1.2.4.2 keiichi 59 1.2.4.2 keiichi 5. Virtualization Jails via secmodel 60 1.2.4.2 keiichi ------------------------------------ 61 1.2.4.2 keiichi 62 1.2.4.2 keiichi One novel way of creating jails for virtualization is to use a new 63 1.2.4.2 keiichi secmodel (part of the kauth framework), to isolate processes into 64 1.2.4.2 keiichi jail-based virtual machines. This is the basis of a paper to appear 65 1.2.4.2 keiichi in the AsiaBSDcon proceedings in March 2008. 66 1.2.4.2 keiichi 67 1.2.4.2 keiichi Responsible: bad 68 1.2.4.2 keiichi 69 1.2.4.2 keiichi 6. iSCSI booting 70 1.2.4.2 keiichi ---------------- 71 1.2.4.2 keiichi 72 1.2.4.2 keiichi In order to make Xen domains migration-friendly, the storage that the 73 1.2.4.2 keiichi domain uses must be based on some form of network-centric storage, either 74 1.2.4.2 keiichi NFS, or a SAN or IP-SAN. For IP-SANs, iSCSI booting will be used. 75 1.2.4.2 keiichi 76 1.2.4.2 keiichi Responsible: agc 77 1.2.4.2 keiichi 78 1.2.4.2 keiichi 7. iSCSI device cloning 79 1.2.4.2 keiichi ----------------------- 80 1.2.4.2 keiichi 81 1.2.4.2 keiichi To minimise the storage requirements for multiple domU booting, using 82 1.2.4.2 keiichi a standard root filesystem or block device for the domU is required, along 83 1.2.4.2 keiichi with some form of copy-on-write mechanism to preserve any modifications 84 1.2.4.2 keiichi that are made. 85 1.2.4.2 keiichi 86 1.2.4.2 keiichi Responsible: agc 87 1.2.4.2 keiichi 88 1.2.4.2 keiichi 8. Xen domU migration, suspend and resume 89 1.2.4.2 keiichi ----------------------------------------- 90 1.2.4.2 keiichi 91 1.2.4.2 keiichi Xen domU migration is where a domU domain is moved from one dom0 to 92 1.2.4.2 keiichi another dom0 on the same vlan (to avoid networking problems, the 93 1.2.4.2 keiichi virtual arp address migrates with the domU itself). 94 1.2.4.2 keiichi 95 1.2.4.2 keiichi Responsible: bouyer 96 1.2.4.2 keiichi 97 1.2.4.2 keiichi 9. Xen balloon driver support 98 1.2.4.2 keiichi ----------------------------- 99 1.2.4.2 keiichi 100 1.2.4.2 keiichi The balloon driver allows more memory to be added to a running Xen domU 101 1.2.4.2 keiichi instance; this allows extra memory to be used by the domU for resource 102 1.2.4.2 keiichi peak needs. 103 1.2.4.2 keiichi 104 1.2.4.2 keiichi Responsible: bouyer 105 1.2.4.2 keiichi 106 1.2.4.2 keiichi 107 1.2.4.2 keiichi Alistair Crooks 108 1.2.4.2 keiichi Thu Mar 6 22:36:19 GMT 2008 109
