Does puppet export a variable containing the name of the module currently being processed? That is, if i''m reading the file "modules/ntp/manifests/whatever.pp", is there any puppet variable containing the string "ntp"?

I've tried with KSM disabled and nothing changed. I've upgraded KVM to qemu-kvm-ev. I'm waiting to see if there are any improvements and report back. ?n mie., 17 aug. 2016 la 15:10, Boris Derzhavets <bderzhavets at hotmail.com> a scris: > For myself KSM is unpredictable feature.

Hi, First question: "/module" is mapped to a special file that reads a kernel module passed in by the bootloader. Much like GRUB, kiwi's bootloader loads a kernel and can load one or more extra files into memory. These are passed to the kernel. The horizon kernel expects one file, which it makes accessible at "/module". This should be set up to be whatever you set

Hi James, I have two questions for you. Firstly, what is the role of 'module' in init.cc? I can see that its being treated like it is a 'bytecode' file, as we open it and then pass it to the ByteCoder and eventually construct llvm module from it. Like In file init.cc, line:121 FILE *stream = fopen("/module", "rb"); ... fread(c, 1, sz,

Yes. It is on both baremetal and compute node. ?n mar., 16 aug. 2016 la 13:37, Boris Derzhavets <bderzhavets at hotmail.com> a scris: > Is KSM enabled on your Compute Nodes ( presuming CentOS 7.2 on bare metal > ) ? > > > ------------------------------ > *From:* centos-virt-bounces at centos.org <centos-virt-bounces at centos.org> > on behalf of Laurentiu Soica

Laurentiu, Just to chip in, without thoroughly checking the thread (which I'd like to apologize in advance for): have you tried to test other kernel instead of the stock one? You can have a look at http://elrepo.org/tiki/kernel-ml and http://elrepo.org/tiki/kernel-lt and use them for some comparison testing.

Hi Mian, Looking at the runlog, everything seems fine until LLVM attempts to use lseek() on a file. You see the PANIC because Horizon hasn't implemented lseek yet. Obviously the version of GlibC I was using does not use lseek in that circumstance, but yours does. You just need to implement lseek :) Cheers, James -----Original Message----- From: Mian M. Hamayun

Hello, The issue reproduced again and it doesn't look like a swap problem. Some details: on the baremetal, from top: top - 08:08:52 up 5 days, 16:43, 3 users, load average: 36.19, 36.05, 36.05 Tasks: 493 total, 1 running, 492 sleeping, 0 stopped, 0 zombie %Cpu(s): 3.5 us, 87.9 sy, 0.0 ni, 8.6 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st KiB Mem : 12357451+total, 14296000 free,

For myself KSM is unpredictable feature. The problem is Compute, just this node does "copy on write" , so only Compute. My concern exactly is where would it lead to worse or better Guest behavior ? I am not expecting complete fix. I would track via top/htop and dmesg via Cron on 1-2 hr period. ________________________________ From: centos-virt-bounces at centos.org

Running the compute node for several days simply triggers it. ?n mar., 16 aug. 2016 la 12:12, Boris Derzhavets <bderzhavets at hotmail.com> a scris: > Sorry, > > How you trigger the problem ? > > B. > > > ------------------------------ > *From:* centos-virt-bounces at centos.org <centos-virt-bounces at centos.org> > on behalf of Laurentiu Soica

No luck with qemu-kvm-ev, the behavior is the same. Running perf record -a -g on the baremetal shows that most of the CPU time is in _raw_spin_lock Children Self Command Shared Object Symbol - 93.62% 93.62% qemu-kvm [kernel.kallsyms] [k] _raw_spin_lock - _raw_spin_lock + 45.30%

It sounds weird, but attempt to disable KSM and see would it help or no ? ________________________________ From: centos-virt-bounces at centos.org <centos-virt-bounces at centos.org> on behalf of Laurentiu Soica <laurentiu at soica.ro> Sent: Wednesday, August 17, 2016 4:56 AM To: Discussion about the virtualization on CentOS Subject: Re: [CentOS-virt] Nested KVM issue Enabled the
