similar to: Enabling KSM with ksmctl under Centos 5.4

Greetings Xen Users, I am trying to bring up xen-4.0.1-0.1.rc4.fc13 on an up to date FC 13 Dell Precision 690. For dom0, I am using the 2.6.32.17 PVOPS kernel. Xen boots and the kernel boots until it reaches a point where KSM fails (as it should, since KSM is compiled out) but hangs, because it cannot find /sys/kernel/mm/ksm/sleep_millisecs and friends. I have booted the kernel on bare metal (KSM

I have had ksm[2] causing a high load (on recent centos7), such things have been reported before[1]. I suspect that this could be related to windows vm's. I am having not that many vm's in the current setup, and this load increased on the hosts with a few windows vm's that are already generating more load that others. Is there a way to disable ksm for specific vm's in the

Hi, Could anyone provide (or point me to) information on how KSM merging behaves when performing live migrations? Does libvirt perform any special work to trigger KSM scanning of the migrated pages? Any guidance is appreciated. James

Hi guys, Any chance we could get KSM support in centos 5.4? Maybe the centosplus ones or a gift from elrepo.

Has anyone here ran performance comparisons between NFS and iSCSI when using network storage for KVM based guests. Also which have people found to be easier for managing live migrates etc. Steve -- Steven Ellis - Bulletin.Net Inc - http://www.bulletin.net

I'm wondering under what circumstances the kvm-clock source is exposed to a guest. I've got a bunch of KVM servers running Centos 5.5 and some of the guests have are defaulting to jiffies or apic whilst some are picking up kvm-clock. Looking at the virtual machine definition file there doesn't appear to be a difference, Any where else to look? Steve -- Steven Ellis - Bulletin.Net

Hi, This is a very very strange thing I have seen in Linux Kernel. I wrote a simple program, all it does is to load a file into memory. This programming is running on a virtual machine while linux-kvm is working as the hypervisor. I enabled ksm in the hypervisor level, my host machine was installed with a Opensuse11.4 while the guest OS is Fedora14, the strange thing is, whenever I run following

Running Centos 5.4 with KVM on a Dell R610 server and I'd like to control which of the four ethernet interfaces are used for specific tasks My ideal configuration would be eth0 - Host traffic only, no virtual guests. Used for guest mirroring and management. eth1 - NAT guest traffic only, no address for local machine and in some environments in the same zone as eth0 eth2/3 - Allocated to two

All, Could this patch in any way cause problems with samba?

Is anyone else having major I/O peaks due to logrotate or other jobs running simultaneously across multiple guests. I have one KVM server running Centos 5.4 with local disk that is seriously suffering as most of the guests rotate their syslog at the same time. Looking at the KVM server I'm seeing 11:00:01 PM CPU %user %nice %system %iowait %steal %idle 03:40:01 AM

I'd like to revisit and old post if I may, will/does Dovecot support the old qpopper "Bulletin" ability? Basically I need a simple way of posting bulletins to all domain users. Qpopper maintained a bulletin db for each user and sent them the next bulletin in sequence. Thanks in advance Kevin

Dear all: I am a newbie for Xen, and now I want to install Xen on my Fedora 13 machine. I follow Mr.Pasi Kärkkäinen''s tutorial, which is "Fedora 13 Xen 4 Tutorial", but I can not boot with the new kernel. I can not go through the step "Verify the Xen step after reboot", when I reboot and choose the new kernel, the system hang on "Starting xend daemon", so

Hi. I'm running FreeBSD with Samba 3.0.28 and have had success previously with FreeBSD and an earlier version of Samba, and am in the process of setting up a member server to act as a file server using the above combination.

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.
