The software to manage this is now called PowerVM (its been called other names in the past, not all polite). In addition, AIX 6.1 and newer have Workload Partitions (WPAR), which are similar to Solaris Zones, these allow subdividing an AIX install into an arbitrary number of apparently different systems that all share the same kernel. LPAR plus VIOS (Virtual IO System, actually a stripped down preconfigured AIX system) corresponds to the Xen model, however the base hypervisor capability is built right into the CPU and IO hardware, VIOS just provides management and optional virtualized IO. You can assign IO adapters directly to partitions, whereupon the partitions (VMs) run even if VIOS is shut down. The newer Power6 and 7 servers have Ethernet adapters that provide each LPAR with its own hardware-virtualized ethernet adapter so you don't need a cage full of cards, or run all the networking through VIOS. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos This is why I'm not totally impressed with virtualization today, but I've used it ions ago in enterprise solutions. =) There's a reason why IBM solutions are so expensive sides the amount of people they staff on projects.

I always liked the way you could NFS-install from a directory containing the downloaded CD iso images but I could never get that to work with a dvd iso. Is there an equally easy way to install from a DVD image on a box without a DVD drive? Yes, it's still possible, but needs a little bit more work. In the directory where the DVD ISO is, you have to create a directory called images and put the install.img file from the ISO there: [someone@ftp x86_64]$ ll -R .: total 3953768 drwxr-xr-x 2 root root 4096 Nov 12 15:25 images -rw-r--r-- 1 root root210 Nov 12 12:31 MD5SUMS -rw-r--r-- 1 root root 232761344 Oct 26 03:16 rhel-server-6.0-x86_64-boot.iso -rw-r--r-- 1 root root 3431618560 Oct 26 19:09 rhel-server-6.0-x86_64-dvd.iso -rw-r--r-- 1 root root 380297216 Nov 4 21:48 rhel-server-supplementary-6.0-x86_64-dvd.iso ./images: total 119780 -r--r--r-- 1 root root 122527744 Sep 23 00:04 install.img Regards, Simon ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Sonetimes back, I remember reading that the plan was to spread the iso's over multiple cd's, rather than put it all on 1 dvd. Is that still the plan? As far as when it's released, I say take all the time you need. I'd rather have an os that works, than something that's just thrown together, and is about as stable as windows me, or vista. That will depend upon how upstream wrote the item that splits the RPMs. The distros are getting so big now that it might not make sense to continue to create CDs ... CentOS 5.6 will have at least 8 (and maybe 9) CDs for x86_64. I would expect that number to grow for CentOS 6. In fact, we already had to split 5.5 x86_64 over 2 DVDs, and both arches for CentOS 6 will likely be 2 DVDs. How reasonable would it be to offer DVD images that fit on DL media? I know I don't own any DL media, and probably most others don't either, but I at least do have DL-capable optical drives. If a good enough reason came up, e.g., my favorite distro making DL isos available, I'd probably go buy some. -- Fred Smith -- fre...@fcshome.stoneham.ma.us - For the word of God is living and active.

[informative text snipped] Yes, it is some nice stuff... In particular, having the hardware partitioning capability plays nice with Oracle licensing. Under KVM or Xen we still have to license the entire system. This probably won't change with the newer kvm, but one can hope. On the Linux side I would like to see how KSM (kernel memory merge) stacks up against memory compression on the Power7 side. Not sure if this made it into RHEL6, but hope springs eternal... Storage management is always a big issue for me. AIX has some really great tools for managing disks. In Linux the LUN, block and fs layer are still relatively decoupled which gives an enormous amount of flexibility but certain types of changes require multiple commands on Linux. On the desktop side I've been running RHEL6 as my primary environment since release. Transition was easy. My old kickstart files needed tweaking, but so far it's been a breeze. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
