VM's in a HA-configuration - synchronising vm config files
Hi,
i'd like to establish a HA-Cluster with two nodes. My services will run inside vm's, the vm's are stored on a FC SAN, so every host has access to the vm's. But how can i keep the config files (xml-files under /etc/libvirt/qemu) synchronised ? Is there a possibility to store the config files somewhere else ? E.g. a partitition with ocfs2 on the SAN ?
If not, what would you do

virsh uses internally qemu-img ?
Hi,
i read that virsh uses internally qemu-img (http://serverfault.com/questions/692435/qemu-img-snapshot-on-live-vm).
Is that true ? so snapshotting a running vm with virsh or qemu-img is the same ?

snapshot of running vm's
Hi,
i'd like to create snapshots of my running vm's. I have several hosts with
SLES11 SP4 64bit. I use libvirt 1.2.5-7.1 . VM's are Windows 7, SLES,
Ubuntu, Opensuse.
I use raw files for the vm's.
I try to orientate myself by
http://wiki.libvirt.org/page/Live-disk-backup-with-active-blockcommit .
The hosts are backuped every night by a network based backup solution
(Legato).

which is the config file for a vm ?
Hi,
i have a weird problem. I have a vm (KVM) which seems to run fine. I believe the respective config file for this vm is /etc/libvirt/qemu/MausDB.xml. This is it:
=========================================================
<domain type='kvm'>
<name>MausDB</name>
<uuid>d4c7956c-b57f-967a-0454-99835a3a740b</uuid>

snapshot with libvirt tools or with lvm tools ?
Hi,
i asked already a time ago about snapshots. I have some guests, each resides in a raw file, placed on an ext3 fs which is on top of a logical volume, for each guest a dedicated lv.
The raw is not a "must have", if there are obvious reasons i can convert them to a qcow2.
What i want is a consistent backup of each guest taken overnight. If possible i won't have downtime.
I can use

rsync of a reflink from OCFS2
Hi,
i have some virtual machines running on logical volumes formatted with OCFS2. I'd like to snapshot the running guests
to backup them easily afterwards. The files of the guests are big (100 - 300GB), but the content changes only slowly.
So i thought that rsync would be a great benefit because it justs transfers the difference between the current file and
the one backuped one day before. I

vm running slowly in powerful host
Hi,
i have a vm which has a poor performance.
E.g. top needs seconds to refresh its output on the console. Same with netstat.
The guest is hosting a MySQL DB with a webfrontend, its response is poor too.
I'm looking for the culprit.
Following top in the guest i get these hints:
Memory is free enough, system is not swapping.
System has 8GB RAM and two cpu's.

how "safe" is blockcommit ?
Hi,
currently i'm following https://wiki.libvirt.org/page/Live-disk-backup-with-active-blockcommit. I 'm playing around with it and it seems to be quite nice.
What i want is a daily consistent backup of my image file of the guest.
I have the idea of the following procedure:
- Shutdown the guest (i can live with a downtime of a few minutes, it will happen in the night).

Hi,
i'd like to install R 2.5 on an Ubuntu 14.04.
I have a special software requiring this old version.
While ./configure, i get the following error:

checking for X... no
configure: error: --with-x=yes (default) and X11 headers/libs are not available
The problem is that i don't know which headers or libraries are missing, and when i search with aptitude in

R 3.4 has broken C++11 support
Hi,
This commit (I?m using the mirror to have a working link) broke C++11 compilation.
Before (and still now, according to the comments in the configure script), it?s sufficient to just have ?SystemRequirements: C++11? in the DESCRIPTION file.
But now ?R CMD install? fails with ?C++11 standard requested but CXX11 is not defined?, which is, according to the documentation , a lie.

experience with balloon memory ?
Hi ML,
i'm thinking about using balloon memory for our domains. We have about 15 domains running concurrently,
and i think it might be nice if a domain requires more RAM it grabs it, and if it don't need it anymore, it releases it.
But i have no experience with it. So i have some questions:
- is live migration possible with balloon ?
- is it stable ?
- the domain needs an appropriate

R 3.4 has broken C++11 support
Hi!
Well, my linux distribution has very recent versions
of everything, so a working C++11 compiler exists:
$ gcc --version | head -n1
gcc (GCC) 6.3.1 20170306
Could wrong ./configure options be at fault here? See:
https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=r-devel#n40
My sessionInfo():
$ R-devel --slave -e 'sessionInfo()' | head -n3
