I chose virtualization when installing Centos 5.3. The kernel I got is 2.6.18-128.el5xen My plan is to use KVM, I disable xend service. I don't need a xen enabled kernel. How do I update the kernel to a non xen one?
View 1 RepliesI installed the latest version of Centos 5.4.It came with Xen version 3.0.2 I think.I am running it on a Dell R510. It supports hardware virtualization.I was able to virtualize Windows XP and Windows 2003 server on it by selecting the install from DVD option.I was having problems trying to get a PCI DekTek card seen by the virtualized Windows domains so I tried to upgrade XEN to 3.4.2.I used the repos available from Gitmo and it went easy.
The only problem is now that when I try to create a "New virtual host" it only allows me to use HTTP, FTP option and not the iso or DVD option. They are greyed out. I was wondering if anyone has had this problem and might know a work around for the Xen 3.4.2 problem. Perhaps a better location for the kernel or something.
i'm a familiar with Linux environement ( fedora 10 user ) and i got a project in a training where i have to create a cluster with two nodes where i have to set up a number of VMs that will run applications such as ( Samba, Ldap, Zimbra, ...) but i don't know how to virtualize on top of a cluster ! i would like to know how that can be done, and how is it possible to let the VMs get ressources ( RAM & CPU ) from the two nodes ??
View 1 Replies View RelatedI have a customer who has (currently) three servers running Centos 5.5, one running Windoze 2003 and around thirty or so workstations running XP Pro.
I've just been reading about RedHat's product - RHEVD and was wondering of anyone knows if this product (or anything similar) is aavailable under CentOS.
Basically what we need to be able to do is to virtualize the XP workstations so that the staff can connect via a browser (inside the office or off-site - or for that matter anywhere) and be presented with a standard desktop.
I know I can achieve this using Citrix XenDesktop or VMWare View but I would prefer to use a FOSS solution if one exists. Having said that it has to be robust and well past Beta

No fonts found; this probably means that the fontconfig library is not correctly configured. You may need to
edit the fonts.conf configuration file. More information about fontconfig can be found in the fontconfig(3) manual page and on [url] Domain installation does not appear to have been successful. If it was, you can restart your domain by running 'virsh start solhvm123'; otherwise, please restart your installation.

The word on all lips are "virtualization" so I decided to smell this flavor.
I have a machine running CentOS 5.3 64bit and I have unlimited access to this machine, but I don't want to reach it physically.
Is it possible to install and maintain a virtual medium using ssh or other remote connection?
When I installed the OS I have selected the packets regarding the virtualization, but now from where can I start?
Is somewhere a guide for doing this?
If you select "support virtualization" during install, you get the xen kernel installed.
Some things do not work with this kernel (e.g. nVidia drivers). So my question is whether it is possible to install both kernels (xen and ordinary) and select between them with grub at boot time?
I did try this a while ago, by first installing with xen and then manualy adding the ordinary kernel, but the ordinary kernel failed to boot (for reasons I don't now recall - sorry). Clearly, there must be differences in the "virtualization" build other than the kernel.
The alternative, if I want to play with virtualization, would be to have two entirely separate installations, but this seems like a waste of space when surely almost everything must be identical?
I can't find anything in the Centos Xen documentation about this.
Before I try again I would just like to check if anyone actually knows if this is possible, or if not why not?
Or can it be done with KVM?
I have CentOS 5.5 and try to create KVM virtual machine with CentOS 5.5 as a guest. But when I exec command:
virt-install --connect qemu:///system --name test --ram 1024 --file=/var/lib/libvirt/images/test.img --file-size=10 --vnc --cdrom=/var/lib/libvirt/images/CentOS-5.5-x86_64-bin-DVD-1of2.iso --vncport=10000 --accelerate --os-type=linux --nonsparse --livecd --hvm
I had just put the last touch on a snort, mysql, apache, barnyard, base isntall to CentOs 5.3. I noticed that ifconfig displayed an odd virtual nic, and I wanted as little running on this machine as possible. I don't remember specifying that I wanted XEN installed. And on the old lowend machine that is powering this server, Virtualization was the last thing I wanted running on it. I did a google, discovered that the way to remove XEN completely (yum uninstall xen' only removed 'xen' but still, oddly, xen was running after a reboot. Talk about perplexing.

I've installed CentOS 5.3 on a machine, and I need a Samba version 3.2 or higher. Since 3.4 is out, I thought I'd grab that. But, "yum list|grep samba" gives me only version 3.0.33. Is there a package of Samba I can grab that will upgrade the 3.0 installation so that I don't have two laying around? If not and I need to compile from source, do you have any suggestions for what arguments I should give configure? I'm not used to Linux coming from the BSD world
View 1 Replies View RelatedI just upgraded by box from Fedora Core 9 to Centos 5.2. Finally!I have a 500GB SATA drive, it's partitioned into three equal size slices, hda1 through 3. The old Fedora was on hda1, I installed the new Centos on hda3. I instructed the installer to write the MBR to /dev/hda, not /dev/hda3. Fdisk says I have sector 0 unused.First, the system wouldn't boot - it just looped through the BIOS, rebooting over and over again. The BIOS sees the disk, but it never loaded Grub. I tried re-running grub-install /dev/hda, and not I get a Grub Error 17 after stage 1.5 loads.
I can boot from rescue OK, the grub.conf man menu.lst look fine, it's pointing to "root (hd0,2)". It's either the BIOS that can't find the MBR, or the MBR can't find Grub.When I looked at the disk with fdisk after the install, hda1 was still marked bootable, hda3 was not, so I swapped bootable flags but that has not made a difference. I also appended the new grub to the old grub thinking I could get the MBR (if it is there) to load the old grub and thence find the new Centos, but that didn't work either.Mobo is an old Shuttle AK35.Any ideas? Did I mess up by not telling the system to put the MBR on /dev/hda3? Is there a way to fix this without reinstalling?

View 12 Replies View RelatedI was wondering if anyone can assist me. I am looking to build a server with Debian as the host. When I installed Debian (Squeeze) the default kernel was "2.6.32-3-trunk-amd64". When I tried to install 'Virtualbox' application, I got a failure because I didn't have the 'kernel-headers' installed on my machine. I noticed there are no specific header package the 'trunk' kernel I was using. I have a few questions so I guess I should begin:
Is it safe to remove the 'trunk' kernel and boot my system on just the regular 2.6.32-3-amd64 kernel? Is this OK or not recommended? Please explain whatever is the correct answer. This is my 1st time using a 'Trunk' kernel so I don't know the in's and out's of it.

I am leading a project at work that will require at least one new server. There will be a development server and a production server, which changes from development will be rolled onto. Unfortunately, I am more of a web programmer than a Linux guru, and I really don't know whether or not it is better to have two physical servers or two virtual servers on one machine. I don't think there will be a huge toll on the machine, as there will probably be around 1000 total users and less than 100 on at any given time. We are also able to spend quite a bit on the server, so I'm sure one could handle it, but I just wanted to check and see what the advantages and disadvantages would be in this situation.

View 3 Replies View RelatedOne of the things holding me back from building a new system with nothing but Linux is the vague possibility that that I might need to use some proprietary program that only works on Wind'ohs in the future.

But buying a new 64-bit version of Wind'ohs for ~$200 seems a waste.Is it now possible to run XP in a "virtual" machine under Debian? More importantly, is it possible to install XP completely from within the virtual machine so it never sees the > 4 Gb or RAM and freaks out? What sort of hardware is required to do something like this? I presume a CPU with certain special capabilities is essential, but wouldn't those special instructions (whatever they are) be pretty standard now? Would the virtual XP install need its own partition?
