I've noticed that OEMs have gone back and forth with AMD over the years in their attempts to build more power efficient with each new generation. Or its because Joyent and Intel have a pretty good relationship, and Joyent didn't want to help Intel's competitor: http://www.prnewswire.com/news-releases/joyent-secures-funding-from-intel-capital-70300952.html http://www.joyent.com/2010/10/intel-selects-joyent-for-intel%C2%AE-cloud-builders/ http://www.intelcloudbuilders.com/ourpartners/joyent -- Venlig hilsen / Kind regards Jeppe Toustrup (aka.

I would like to know, now that is KVM here in Illumos (and presumably in OpenIndiana and when also AMD CPU support is written, beside Intel support), does that means we have something more powerful than XEN is? Depends how you define 'powerful' :) Architecture in Xen is quite different from KVM.. Xen has: - Thin hypervisor (around 2MB in size) - much less code than OS kernel - Thin interfaces between domains (VMs) - Strong isolation between domains - Xen driver domains -concept: virtual net/disk backends for VMs don't need to be in dom0, backends can be served from special driver domain VMs! Making the system disaggregated and very secure. I do not know if all Joyent's upgrades they made to illumos (ZFS disk bandwith for zones, etc) ends up inside Illumos? Since Oracle left working Xen in S11Ex for 64-bit x86 host but is pushing it's closed Xen implementation and Xen support is currently not quite maintained in Illumos/OpenIndiana, maybe KVM is what one could use (beside Virtualbox). Yep, that's the problem.. Xen support in Illumos/Openindiana needs some work. - Someone should upstream the XVM hypervisor patches to upstream Xen hypervisor - so you could use the stock Xen hypervisor in Illumos in the future - Someone should make sure the Illumos/OpenIndiana kernel properly runs as Xen dom0 - Bugfixing, testing and maintenance in general needed - Someone should make sure Illumos/OpenIndiana kernel properly runs with PV drivers as Xen HVM guest That will be some work, yes, but the good thing is that it is (and has been) already working in OpenSolaris.. Example of Xen Driver Domains: - Run Xen with Linux dom0 (or Illumos dom0, if someone starts working on Illumos Xen support). - Create Illumos/OpenIndiana VM (Xen HVM probably to take advantage of CPU hardware virtualization and EPT) - Use Xen PCI passthru to pass disk controller (HBA) to the Illumos/OpenIndiana VM - Run ZFS in the Illumos/Openindiana VM, with direct access to the HBA and disks. - Make sure the Xen backend-drivers from OpenSolaris run properly in Illumos/OpenIndiana, and run them. - Serve disk backends to other VMs from the Illumos/OpenIndiana driver domain from ZFS! That would be very interesting setup! -- Pasi ___ OpenIndiana-discuss mailing list OpenIndiana-discuss@openindiana.org http://openindiana.org/mailman/listinfo/openindiana-discuss
[OpenIndiana-discuss] virtual nic an routing
I have a virtual nic (vnic) on oi_148 dladm create-vnic -m random -l igb0 vnic2 ipadm create-addr -T static -d -a 192.168.11.127/24 vnic2/test Interface igb0 has an IP of the same subnet of vnic2 Whitout VNIC, outgoing packets have the igb0 ip address. Ok. With VNIC configured and enabled, outgoing packets have the vnic2 ip address. If I add a second vnic, outgoing packets will have the ip address of such second vnic. The routing table is as follow netstat -nr Routing Table: IPv4 Destination Gateway Flags Ref Use Interface - - default 192.168.11.1 UG 7 10763 192.168.11.0 192.168.11.127 U 3 3033 vnic2 192.168.11.0 192.168.11.50 US 7 8224 igb0 127.0.0.1127.0.0.1UH2 168 lo0 There is a way to set priority or precedence? Even if I use ifconfig vnic2 deprecated, as stated in the man page, outgoing packets have vnic2 ip address as source ip.
