KVM, virtualized interface, dropped packets.
Hi All.
I have currently a small problem to solve. I have a kvm virtual machine
which in output of
ifconfig eth0 | egrep 'RX packets|TX packets'
RX packets:792681304 errors:0 dropped:560728 overruns:0 frame:0
TX packets:716661674 errors:0 dropped:0 overruns:0 carrier:0
show dropped packets. I think that rx buffer is to small (no strange

[PATCH] drm/nouveau: POST the card before GPIO initialization
Otherwise my card (nv92) never resumes from suspend to ram, hanging on
nv_mask in nv50_gpio_drive. Before rework, initialization was done only
from POST, so this patch restores previous behaviour.

What gui to use for syslog-ng logs?
Hi All.
I have an environment in which I would like to implement a GUI for parsing
syslog-ng logs from operating system, application servers and databases.
I've heard that Splunk is a good tool but its quite hard to learn. Are
there any valuable alternatives? What are you using and why?
Best regards,
Rafal.

recommend?

Netconsole capability in ramdisk
I'm supporting a number of consumer devices (e.g. small NAS devices)
in Debian. They typically don't export the serial console and don't
have any other output devices. We perform the installation via SSH
on such devices and start SSH automatically when the system boots so
people can login. This works pretty well but sometimes a device stops
to boot for no good reason. This is

NFS mount auto remount in case of problems.
Hi All.
I have a setup in which I have two servers serving nfs share. The nfs
service is made highly available with pacemaker. When the primary
server goes down the secondary starts nfs service. Service IP is
floating between servers but they have NO "shared" storage/filesystem
so NFS state/connection information in case of failover is lost. I
have two clients. When the failover from

XEN or KVM - performance/stability/security?
Hi all.
I am currently building a small test cloud based on Eucalyptus 2.0.3 and
CentOS 5.8 x64. I have a choice which hypervisor to use: KVM or XEN.
KVM is the default in CentOS 6 but I have read also many good things (for
example PV guest machines, isolation between Dom0 and DomU) about XEN.
Key factors from my opint of view are:
- stability (which one runs more smoothly on CentOS?)

Memcached - replication?
Hi all.
I am thinking about installing memcached with replication, I've found
http://sourceforge.net/projects/repcached/files/repcached/2.2.1-1.2.8/ but
it is for 1.2.8, and for Centos 6.3 memcached is in version 1.4.4. I do not
want to use client side "replication" (writing to two memcached nodes at
the same time) and haven't found other solution.

mbox files - can they be "compacted"?
Hi All ;)
Is there an option to compact large mbox files from the shell? I did not
find anything in google, I have some very large constantly updated mbox
files and would like to know if they can be made smaller with any tool.
AFAIK mutt does such operation when for example an email is deleted but I
am curious if there are other options.

Strange behaviour when using sudo+sh+executable.

I am trying to install some software. Part of its installation is an

Centos 6 full backup software?

I need a good tool to backup whole system on block level rather than file
level and easy to use. I currently need to backup to an USB disc (50+ GB of
data) a system and then reinstall it. In the future if needed I will revert
to the system from backup ;)
What can you recommend?

syslog-ng or rsyslog?
Hi All.
I've used syslog-ng for some time. I like it. I have a project in which I
need to choose a central logging solution. What are your experiences with
rsyslog? Is it more complex to setup than syslog-ng? Or maybe does it have
some additional features?
I am also thinking about using some gui tools for log parsing and graphing.
May be proprietary/paid. Any suggestions?

Proper check of openssl usage in processes?

I need to check and possibly update openssl on my fleet of servers. I would

- update openssl version with yum
- check all daemon processes which are constantly running in the os, for
example for sshd something like

So I would like to:

- stop gluster software on master (already stopped on slave);
- remove gluster software on master and slave (previous
