Hey guys, I'm so glad you added the new set of virConnectListAllDomains functions, it simplifies a lot our work!. I was only wondering why there is no support for PowerVM. Is it that it hasn't been developed or is there some technical hardship? Best, Camilo Aguilar

...* The Microsoft Hyper-V <http://libvirt.org/drvhyperv.html> hypervisor /"the goal of libvirt: *to provide a common and stable layer sufficient to securely manage domains on a node, possibly remote*."/ My question is, does redhat's libvirt team have the plan to support IBM PowerVM hypervisor? If the answer is NO, what's the reason to make the support for IBM PowerVM hypervisor doesn't make sense... BRs, Dennis -------------- next part -------------- An HTML attachment was scrubbed...

I'm writing Go bindings, I was just wondering about PowerVM, maybe further ahead if nobody has done it I could give it a try. So, Does it mean the other functions more granular funtions are going to be deprecated at some point? On Tue, Nov 5, 2013 at 10:18 PM, Daniel P.

greetings folks. wanted to have aix detect if it was under powervm using facter. came up with this hack for facter 1.6.9 which work for vscsi and npiv enabled vm''s under powervm (so far)... havent checked the dev facter so something may be in a different branch already for facter on this topic... -- You received this message because you are subs...

I believe it was probably just an oversight - our intention was that the new API worked with all drivers. Feel free to send a patch for phyp if you think you can manage to write the code.

And we read the yield_count of this struct to detect if one vcpu is running or not. SO it's easy for ppc to implement such interface.

.... We have a few NICs on the server, one of which we would like to dedicate to network traffic to/from the virtual guests. Is it possible to do this without assigning an IP address to the NIC? We're currently doing something like this with Vmware Server, HP's HPVM for HP-UX/IA, and IBM's PowerVM for AIX. -- albert chin (china at thewrittenword.com)

change from v2: __spin_yeild_cpu() will yield slices to lpar if target cpu is running. remove unnecessary rmb() in __spin_yield/wake_cpu. __pv_wait() will check the *ptr == val. some commit message change change fome v1: separate into 6 pathes from one patch some minor code changes. I do several tests on pseries IBM,8408-E8E with 32cpus, 64GB memory. benchmark test results are below. 2
