Jun 20, 2010I installed the Centos 5.5 with XEN and put 03 virtual machines (Centos 5.5 too). I did this correctly, but I have a problem. In the virtual machine, I need update the kernel. I used "yum update kernel" and this is downloaded correctly and the menu.lst file is updated too, but the kernel not ran. I ran "grub-install /dev/sda" or "grub-install /dev/xvda" and received a error return. I read the device.map file and i ran "grub-install /dev/sde" and received a error return too.
The errors:
[root@vm01 ~]# grub-install /dev/sda
/dev/sda: Not found or not a block device.
[root@vm01 ~]# grub-install /dev/sde
/dev/sda1 does not have any corresponding BIOS drive.

Aug 25, 2010I'm running CentOS 5.5 x64 and have just installed VMWare Server 1. I am able to create a new Virtual Machine, but when I go to power on the VM in order to install the OS (windows server 2003), either the host crashes/reboots (with "Run in Debugging Mode" turned on) or the VM simply does not start (with that Debugging box unchecked) and in the log there is an error along the lines of VMware Server unrecoverable error (vmx)

May 18, 2010I'm trying to set up a virtual machine environment in Centos5.5. My hardware fully supports virtualization, and I'm running qemu as the hypervisor with Virtual Machine Manager as the GUI to manage and create VMs. Host hardware is a Dell PowerEdge T710, with a quad core Xenon processor and four 1TB disks in a raid 6 array.
Within the Virtual Machine Manager when trying to create a new VM, there is the option to not "allocate entire virtual disk now". What format is created when you "allocate entire virtual disk now" and when you don't?
I want to create a qcow2 image format, but it doesn't look like it is supported. Does anybody know how to create a VM with a qcow2 image format?
When you create a blank disk with "qemu-img create -f qcow2 disk.qcow2 3700G", it indeed does create a qcow2 image. However, Virtual Machine Manager is unable to read these images, claiming that it is 15 megs or so in size (which is what it actually occupies in host disk space until you try and put a VM into it).
CentOS 5 Networking :: VMware Server 1.0.8 - Cannot "send" A PING To The Virtual Machine
Nov 14, 2009I have Linux server with VMware Server 1.0.8. When I creating a virtual machine, I can not "send" a PING to the virtual machine. In the virtual machine, I have installed CentOS 5.3 (32bit). In the virtual machine I have defined the addresses IP. So, whey I can't "sent" a ping to the virtual machie? I have to set something on the Linux server?

Fedora :: VirtualBox - Failed To Start Virtual Machine
Feb 19, 2010after upgrading VirtualBox from 3.0.x to VirtualBox-OSE-3.1.2-1.fc12.x86_64 VBox fails to start any virtual machine with error: Failed to open/create the internal network 'HostInterfaceNetworking-eth0' (VERR_SUPDRV_COMPONENT_NOT_FOUND).
When I run
sudo /etc/sysconfig/modules/VirtualBox-OSE.modules
I get
FATAL: Error inserting vboxnetflt (/lib/modules/2.6.31.12-174.2.19.fc12.x86_64/extra/VirtualBox-OSE/vboxnetflt.ko): Invalid module format

Kernel is (obviously) kernel-2.6.31.12-174.2.19.fc12.x86_64, but same thing happens with any installed kernel, IE kernel-rt-2.6.31.12-1.rt20.1.fc12.ccrma.x86_64
I reinstalled VBox and kmods got rebuilt but the problem persists.

CentOS 5 :: Create Virtual Machine From Existing Image?
Jan 3, 2011I had set up 4 virtual machines on centos 5.5 system where I directed the image locations to an external storage. I have lost the image files in the storage, but I have the image files that were copied from the virtual machine image location. I want to put up the same system on the same computer by copying these backup images. However, when I copy the image file to the same exact location and start the corresponding virtual machine I get "no bootable disk" error. When I increase the size of the image using "qemu-img" commands, I can get rid of this error, but get "error reading disk" error. Is there a way to overcome these problems, or is it not possible to restore a virtual machine by copying the machine image file under ..../xen/images?

View 8 Replies View RelatedFedora :: Installed CentOS 5 In Virtualbox But Can't Ping The Virtual Machine?
Mar 10, 2009Running Fedora 10, I installed CentOS 5 in Virtualbox, but I can't ping the Virtual Machine...
From within CentOS, I can ping my laptop [known as the host?] but from the laptop I can't ping the CentOS Virtual Machine. I tried turning off the firewall on both too... CentOS was able to access the internet through my laptop right away without any configurations too.
Unless someone has an idea to resolve the above, I am also wondering about something else VirtualBox-related:
To see if it was possible to get around the above issue, I was going to install another CentOS virtual machine to see if I can get them to communicate both ways [if at all], but to do so, I think I have to install CentOS AGAIN on another allocated amount of hard disk space. This will take some time, so I was wondering if anyone knew if it was possible to just create a quick duplicate of the previous installation, if you wanted 2 different virtual installations of the same OS.
Server :: Apache On A Virtual Machine?
Jan 24, 2011I'm Rebuilding all the servers in the company I work for. I read anything I found about best practices in virtualizing, but I didn't find anything about virtualizing Apache. As MySQl is not considered to be virtualized as a best practice but to be on a separate machine - my question is "Do I virtualize an Apache server or put it on another real machine?". And also I'm going to put the server on Ubuntu!

Jan 29, 2010Since a few weeks I cannot open a console in vmware server 2.0.2 anymore. I don't know exactly when this started because I use vmware only occasionally (I have only 1 program (an old Ashlar DrawingBoard) which does not run properly in wine). VMware server and the console have been working before without problems, but now I get the message "Cannot connect virtual machine console." and it times out. This is on Opensuse 11.1 with VMware Server on the same pc, Firefox and the guest is Windows2000.
I have tried to disable all extensions in firefox 3.6, disabled the firewall, even created a new user (on the same pc) with a clean firefox, all without any result. However when I connect from a different computer which runs Internet Explorer under windowsXP, then I can get the console without problem.
So, somewhere there is something wrong between Firefox and VMware server.
General :: DHCP Server Inside A Virtual Machine Can't See Other Machines
Jun 2, 2010I setup a private network from virtual machines and one of the machines is the DHCP server for the group. I want to specify a next-server for the DHCP server but I'm having trouble connecting to any of the machines that I lease IPs to. I'm just trying to do a simple ping/ssh to 10.0.0.252 (a machine with a lease) but it doesn't seem to respond. I'm assuming I need to be able to connect to my next-server but maybe I'm wrong.

Apr 9, 2011I'm a web developer and I am building a site on a CMS that has issues moving from a WAMP server to LAMP. The live server is LAMP and I am running Windows 7. I don't want to run into problems moving from the test server to the live server, so I was wondering if I could somehow run Linux using a virtual machine (using Windows Virtual PC which I think supports Linux or VirtualBox) and then using a Linux equivalent of WAMP2 server as a test server. how to do this and what the best Linux distribution to use would be?

Aug 16, 2011I have an Ubuntu Desktop 11.04 virtual machine using VirtualBox on my Windows 7 system.
Up until now I have been doing all my development within the Ubuntu environment but unfortunately, I don't like it. I want to move back to Windows, which is much more familiar to me but I would still like to access the virtual box like a virtual server as it is already set up with Apache, PHP, Pear, Git etc...
How can I make the two work in harmony? I essentially want to be able to start the VM and connect to it as if it was a server machine somewhere on my network, without having to actually buy another machine to put on my network.
CentOS 5 :: Solution Cluster Fail To Start Virtual Services After Upgrade To 5.5?
May 16, 2010After upgrading Centos 5.4 cluster nodes to 5.5 all virtual services failed to start. All virtual services are marked as 'failed'. The reason: new /usr/share/cluster/vm.sh requires 'which', but this is not reflected in rgmanager-2.0.52-6.el5.centos.
Solution: run 'yum -y install which' on all nodes, and reboot cluster. Hope that will save somebody hours of downtime.
