KSM failure on Xen 4.0.1/FC 13
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

Enabling KSM with ksmctl under Centos 5.4
Are their any good guides out there on how to use ksmctl to enable and
tune KSM performance on Centos/RedHat
At the moment the only guidelines I can find are from the following OLS
paper, plus the Linux Kernel Docs.

Live Migration and KSM merging
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.

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

Strange finding about kernel samepage merging
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

Local lmtp proxy on backend server
I added this:
passdb {
driver = passwd
skip = authenticated
}
Which enables indeed local delivery, I also noticed this. Maybe the
password field check shoud not be done, when you enable skip
authentication?

Sorry I mistakenly overlooked at the ip:s. But anyway that is multiple connections and seems that PAM has some concurrency limit and refuses the third connection Thunderbird opens.

Lightweight LMTP daemon to avoid overkill MTA
I ended up 'hacking' LMTP support into the external spam filter. Someone else already contributed 'real' patches to implement LMTP support, so once I go live with this mail platform it should be stable.

Lightweight LMTP daemon to avoid overkill MTA
Hi,
I was unclear in my question. The spam filter is only able to deliver mail over SMTP, not over LMTP.. So I would still need some kind of daemon that listens for SMTP and then offers incoming email to Dovecot's LMTP socket.

Local lmtp proxy on backend server
I receive a local mail when I do a 'mail test' on a backend svr1 with
this[0] configuration. However when I just add only one configuration
change 'lmtp_proxy = yes' I am getting these errors[1]. I would expect
this email to still be delivered locally, should this be working or do I
misunderstand the lmtp proxy functionality?

Performance mdbox vs mbox
If I do the same test[1] with mbox I can store around 31k messages and
mdbox 16k messages. I noticed also that cpu and disk utilization with
mdbox was not very high, while disk utilization on mbox was much higher.
That makes me wonder if I can tune mdbox to have better performance?
