[Vserver] 64bit centos templates?
so far i found only one centos4 64bit vserver image that was labelled 'default'. it turned out to not even have a text editor other than ed and no way to bring packages into it. no yum or update. does anyone know of a decent image available? ultra-basic is fine as long as it has nano/pico and yum already installed. the 32bit runs fine, but i would prefer 64bit guests (at least i *think* i would). i have a good full featured gentoo one, but a package we need to run for some things requires a redhat-style os. we would have to re-license it to use other than centos. -- Chuck ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver
RE: [Vserver] 64bit centos templates?
About the 64 bit issue and performance. When running on AMD always go for 64bit if you can. When running on Intel, older 64bit implementations are sometimes slower in 64bit than in 32bit. That also holds to newer intel processors including core 2 duo but to a lesser extent where in some benchmarkes it was faster and in some it was slower.

Re: [Vserver] Virtual server monitor
Tom Laermans a écrit : I was planning to make something similar like this, but with a different sort of backend, being an extension into snmpd. I've made different scripts already to be able to monitor daemon stuff through cacti, and was planning on making on one side some nice graphs about load and memory and such, and otherwise an overview page with all the info on it. I would suggest you look at collectd : http://collectd.org/ It collects system information every 10 seconds and writes it into an RRD database. It is implement in C and seems to consume almost nothing in term of ressources on the host. It can monitor vservers too! And it is dead simple to configure. It comes with a simple Perl CGI script to display the graphs. Have a look at these examples : http://tokkee.org/cgi-bin/collection.cgi http://tokkee.org/cgi-bin/collection.cgi/vserver-42097 http://zethradon.no-ip.org:36987/cgi-bin/collection.cgi The first two links point to the server of the author of collectd (Sebastien Harl). The second is an example of vserver monitoring. The third link is my personnal machine. I plan to integrate collectd to vsmon eventually. -- Guillaume Pratte Recherche et développement Révolution Linux Toutes les opinions et les prises de position exprimées dans ce courriel sont celles de son auteur et ne répresentent pas nécessairement celles de Révolution Linux.

When running on Intel, older 64bit implementations are sometimes slower in 64bit than in 32bit. That also holds to newer intel processors including core 2 duo but to a lesser extent where in some benchmarkes it was faster and in some it was slower. MySQL on 64bit AMD is great. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Chuck Sent: Wednesday, September 27, 2006 12:53 PM To: vserver@list.linux-vserver.org Subject: [Vserver] 64bit centos templates? so far i found only one centos4 64bit vserver image that was labelled 'default'. it turned out to not even have a text editor other than ed and no way to bring packages into it. no yum or update. does anyone know of a decent image available? ultra-basic is fine as long as it has nano/pico and yum already installed. the 32bit runs fine, but i would prefer 64bit guests (at least i *think* i would). i have a good full featured gentoo one, but a package we need to run for some things requires a redhat-style os. we would have to re-license it to use other than centos. -- Chuck ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver -- Chuck ...and the hordes of M$*ft users descended upon me in their anger, and asked 'Why do you not get the viruses or the BlueScreensOfDeath or insecure system troubles and slowness or pay through the nose for an OS as *we* do?!!', and I answered...'I use Linux'.

[Vserver] The New Website
I just wanted to say thank you to whomever is responsible for updating the www.linux-vserver.org website. The new wiki is great and very easy to navigate. The 'overview' and 'paper' links on the left side are very informative. I'm not sure if they were present on the old site, but if they were, I never even noticed them. Thanks again.

[Vserver] vmware in vserver?
Is it possible to run vmware-server in a vserver guest? ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver

As VMWare uses a kernel module it makes no sense to try to run VMWare within a VServer guest. VMWare can escape it's guest context through the kernel modules.

I am running kernel 2.6.15.6-vs2.0.2-rc13 with util-vserver 0.30.210. This had been working up until just recently. The command I am using is: /usr/lib/util-vserver/vserver-build --debug --force -m yum -n j_photos \ --hostname=photos.unixguys.com --netdev=eth0 --interface 192.168.1.83 \ --netmask 255.255.255.0 -- -d centos42 The end of the log looks like (no errors earlier on): Are you absolutely sure about that? CentOS 4.2 has been removed from the mirrors, so you should've gotten errors about that. ++ /usr/lib/util-vserver/distributions/centos42/initpost /etc/vservers/j_photos /usr/lib/util-vserver/util-vserver-vars secure-mount: chdir(/tmp): No such file or directory /etc/vservers/j_photos/fstab:2:1: failed to mount fstab-entry vcontext: execvp(bash): No such file or directory An error occured while executing the vserver startup sequence; when there are no other messages, it is very likely that the init-script (bash -c exec /dev/null exec 2/dev/null set -x f=/tmp/startwait trap rm -f $f EXIT mkfifo $f ( sleep 10; kill -s 9 -- -1 ) cat $f /dev/null kill -s 9 -- -1 wait ) failed. Common causes are: * /etc/rc.d/rc on Fedora Core 1 and RH9 fails always; the 'apt-rpm' build method knows how to deal with this, but on existing installations, appending 'true' to this file will help. Failed to start vserver 'j_photos' chroot-shopen(/etc/sysconfig/network): No such file or directory chroot-shopen(/etc/init.d/halt): No such file or directory chmod: cannot access `etc/init.d/halt': No such file or directory chroot-shopen(etc/inittab): No such file or directory This makes it pretty obvious that nothing got installed. You could upgrade to util-vserver 0.30.211-rc2 where centos42 has been replaced by centos4, the more generic name which points to the latest 4 release at all times.

Re: [Vserver] vmware in vserver?
true. I guess there is no point in running vmware in a guest os.

I don't know if I had a mirror that was still available, or what (I did clean out my metadata just in case). Nonetheless, it is working fine now.The next question is, how can I upgrade my centos42 guest vservers to centos4?Thanks!!jorgy___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver
