linux iptables openvz ubuntu-9.10 kernel-modules
After an unsuccessful p2v migration of my Ubuntu server to an OpenVZ container which I am stack with I thought I would give a try to a reinstall based on a clean OpenVZ template for Ubuntu 9.10 (from the OpenVZ wiki)When I try to load my iptables rules on the VM machine I’ve been getting errors which I believe are related to kernel modules not being loaded on the VM from the /vz/XXX.conf template model.I’ve been testing with a few post I’ve found but I was stack with the error:WARNING: Deprecate

java tomcat ubuntu openvz
It’s well known that Java and OpenVZ don’t get along well due to the way memory is managed in OpenVZ — the Java runtime reserves more memory than there is available, or something. This is typically solved by setting a maximum heap size, like so: export _JAVA_OPTIONS=”-Xmx128m”I have two OpenVZ VPSs with the same company; one is based in the USA, and the other in Germany. The American one is running Ubuntu 11 and Tomcat, and the usual fix works perfectly well — without it though, Tomcat will oc

ubuntu java apt openvz
I’m constantly encountering an error related to Java and certificates on my Ubuntu server running in OpenVZ when installing things from apt-get. I’m pretty sure it has to do with how Java allocates memory. I know the fail counter for privvmpages is very high, so the problem must be that Java is hitting this limit.I have read that the server VM will allocate a lot of memory up front to preempt performance issues, but that the client VM doesn’t do this and might be better for what I’m doing.

linux virtualization performance xen openvz
There is a Xen vs. KVM in performance question on ServerFault.What will be the speed difference if the choice is between Xen and OpenVZ?Searching for such benchmarks does not show any results newer than 2008.What would be some important performance measurements to compare OpenVZ against Xen?Some may say “you’re comparing oranges and pineapples” but I have to choose 1 of the 2 and it needs to be a wise choice. Performance is most important to us. We may switch away from OpenVZ because Xen is more

memory virtualization openvz
We’re having a lot of memory problems on a new OpenVZ box. It is supposed to have 1 gig of memory, I’m not sure how much of that is burstable or guaranteed memory. Programs in general seem to take up more virtual memory than they do on my box at home, and on our other OpenVZ box.I wrote this simple C program:#include <stdio.h> #include <stdlib.h>int main(){char *thingy = malloc(500);getchar():return 0; }So it simply allocates 500 bytes and then returns. I ran the program on 3 compute

linux vps openvz virtuozzo
Short Version: Are there any official guidelines on what the kmemsize barrier and limit should be set to for a container in Virtuozzo/OpenVZ intended to be used as a Web server? We’ve found posts in blogs and forums that say that kmemsize should be at least 10% of vmguarpages (after they are converted to the same units). Sadly, nothing we’ve found cited an authoritative reference (or even a reason) for this 10% assertion. Any idea where that 10% idea comes from?Long Version: A client of mine

lvm openvz proxmox
I use Proxmox 2.2 for making OpenVZ containers.It ships with a tool called vzdump that can create backups of OpenVZ containers on the fly. It uses snapshot functionality of LVM to create temporary “fork” of filesystem for backup purposes.Unfortunately it sometimes crashes with one container that performs a lot of disk operations. As far as I know most probably it is because LVM has limited space that it can use for storing changes made to the volume during snapshot.I’ve tried to increase snapsho

Every time I need to create VPSs out of one of our machines, I (re)think the virtualization technologies, and seem to end up with OpenVZ being the most suitable for performance reasons when all I want is clean separation between VPSs. All running GNU/Linux.The question I have is, for a scenario with the following facts, when is it ever more advisable to go for Xen? Here goes the situational facts:I trust everyone who will be using the VPSs, the issue of virtualization security is not a concern T
