similar to: Xen/VMWare Server comparison and "best Xen practices"?

Dear All, When I plot the values and linear regression line for one data set, it is fine. But for another one I see zigzags, when I plot the confidence interval >cd Depth CHAOsep12RNA 9,94 804 25,06 1476,833333 40,04 1540,561404 50,11 1575,166667 52,46 349,222222 54,92 1941,5 57,29 1053,507042 60,11 1535,1 70,04 2244,963303 79,97 1954,507042 100,31 2679,140625 >

Thanks for all the great stuff. Executive Summary: Kernel Parameters or Special Kernel for 5.2 on VMWare? More Details: Is it the best practice to use the specially compiled kernels (when available, typically here: http://people.centos.org/~tru/kernel-vm/5/RPMS/i386/ ) or are kernel parameters now able to achieve the same thing? This bug report: http://bugs.centos.org/view.php?id=2189 seems

I took over a custom firewall script from my older Suse machines to my Dom-Us and it works just fine. Doing the same for Dom-0 immediately killed all traffic for the VMs. As there was no need before I had been dropping everything on the FORWARD chain. After ACCEPTing all for FORWARD my VMs are happy again. What's best practice on Dom-0, what do you do? Can I restrict the forwarding, in

Hi all, If you are using the kernel divider= option in your vmware quest, you are probably aware of the bugs reported at: https://bugzilla.redhat.com/show_bug.cgi?id=315471 Someone @redhat "confirmed" the fix is in the test kernel -92. I tried it but it seems to have the same problem as before - when used with clocksource=pit, it hangs on bootup. Wonder if some of you can test this

Hello I am running CentOS 5.2 in VMWare 6.5. Firefox doesn't run but Konqurer does. VMware host (Vista) is connected to the internet via a DSL router. CentOS VMware network is brided, DHCP is activated, no firewall is acive. Perhaps somebody can help me. Thank you in advance Josef -------------- next part -------------- An HTML attachment was scrubbed... URL:

Evening everyone, I'm trying to install Centos 4.3 in VMWare Workstation running on Windows XP (my laptop). I downloaded the CD iso's to my Linux box and burned them (I did them correctly since last time I screwed them up). However, when I start the VM in VMWare, it says the CD isn't bootable. Any ideas? Thanks! Jeff

Does anyone know how a program, script or shell user can best determine whether the machine is running on bare metal or is a VMware guest? Cheers Tony -- Tony Mountifield Work: tony at softins.co.uk - http://www.softins.co.uk Play: tony at mountifield.org - http://tony.mountifield.org

Everyone, I am in the process of migrating over a samba Linux VM from an openvz based system to a vmware based system.? I am migrating over these services: apache samba rsync (daemon via xinetd) I'm trying to improve my documentation and I want to make a linux vm best practices SOP that can be used as the template for all new server setups.? Does anyone have any similar kinds of

Hi, we are running Centos 5.2 on our servers for some time now and are really happy with it. Now I'm investigating the best way to setup virtual machines in order to streamline our infrastructure. The setup I'm aiming for is Centos 5.2 guests on Centos 5.2 host. The physical systems are going to be 2xquad core Xeons and the VMs are probably going to be 1 or 2 vCPUs with 1 or 2 gb of

I read http://bugs.centos.org/view.php?id=2189 Summary: CentOS is not getting optimal performance in a virtualized environment and on slow cpus but I am not sure I understand the current best practice. Your thoughts would be appreciated. Options as I see them: 1. Run kernel-vm-2.6.18-53.1.4.el5 with clocksource=pit until the excellent CentOS team builds the latest kernel into a VM kernel

Obviously not a very fair comparison [1]. I can''t see how this was done well at all. VMWare are a bit silly to release stuff like this, just lowers the whole game.

This is a continuation of the thread: "yum update fails: CentOS 5.2". I installed a fresh Centos 5.2 and ran yum update. It ran correctly, except for these issues: 1. As previously mentioned, after deciding what it is going to do, It doesn't ask if its ok. But if I type y<enter> it reports: Is this ok [y/N]: Downloading Packages: 2. During the long period it

I've replaced disks in a hardware RAID 1 with larger disks and enlarged the array. Now I have to find a way to tell LVM about the extra space. It seems there are two ways: 1. delete partition with fdisk and recreate a larger one. This is obviously a bit tricky if you do not want to lose data, I haven't investigated further yet. 2. create another partition on the disk, pvcreate another

My Dell server was preloaded with Redhat 7.2 , Linux 2.4.7-10, gccv2.96 with Ext3 file system. I want to install the machine into my company W2k domain using winbind but my Linux kernel does not support the needed ACls. I Does the latest Linux kernel come with ACL support and if so should I just update the kernel to 2.4.19 which I think is the latest production quality kernel? The ACL

Hi All, I have a win2k3 server that its backing up to a CentOS 5.3 server. On the Win2k3 machine I plan to have rsync back up nightly to the CentOS server through ssh. The command I am using is as follows: rsync -vrPtz -e ssh myuser at myserver:/remote/backup/folder/ /local/backup/folder/ This all works great for the inital test except its prompts me for a password for "myuser" (as

One of my customers handed me a copy of this paper and asked why are we using xen if it is so slow... http://morse.colorado.edu/~tlen5710/12s/VMware.pdf which is a fairly damning report of performance under Xen in comparison to VMWare, citing worse than 50% overhead of Xen in comparison to physical. Has anyone seen this paper before? James

Hello If I want to manage a complete disk with btrfs, what''s the "Best Practice"? Would it be best to create the btrfs filesystem on "/dev/sdb", or would it be better to create just one partition from start to end and then do "mkfs.btrfs /dev/sdb1"? Would the same recomendation hold true, if we''re talking about huge disks, like 4TB or so?

I''m trying to get DHCP working with DomU clients. I don''t want to use libvirtd. There''s a dhcpd on the machine and it works fine for all clients in the network, but not for DomUs. If I set a static IP on the DomU all networking for them is fine, so there''s no general networking problem. I use the xen 3.2 packages for CentOS on CentOS 5.1. There was a public

OK, maybe not even best practices, but at least, tested practices. >From my reading thus far, it is evident I shouldn''t use Rails to handle mongrel log rotation. Fine, I''m sold on that. The advice I''m seeing says that that one should use an external script to do this. So my question is, what are people using? What''s working well? Simple bash scripts or

I just saw a mail about the best practices of something or other, and I was wondering is there a place where Ruby and RoR best practices can be found?
